Description Of The Business [Abstract] | |
Description Of The Business | 1. Description of the Business Pulse Biosciences, Inc. is a novel bioelectric medicine company committed to health innovation using an entirely new and proprietary energy modality. The Company’s CellFX ® System is the first commercial product to harness the distinctive advantages of the Company’s proprietary Nano-Pulse Stimulation™ (“NPS”) technology. The CellFX System delivers nano second duration pulses of electrical energy, each less than a millionth of a second long, to non-thermally clear targeted cells while sparing adjacent non-cellular tissue, to treat a variety of medical conditions for which an optimal solution remains unfulfilled. In February 2021, the Company received 510(k) clearance from the U.S. Food and Drug Administration (the “FDA”) for the CellFX System with initial clearance for a general indication for dermatologic procedures requiring ablation and resurfacing of the skin. In January 2021, the Company received Conformité Européene (CE) marking approval for the CellFX System, which allows for marketing of the system in the European Union (EU), and in June 2021, the Company received Health Canada approval for the CellFX System, which allows for marketing of the system in Canada. The CE mark and and Health Canada approvals allow for use of the CellFX System in dermatological procedures requiring ablation and resurfacing of the skin for the reduction, removal, and/or clearance of cellular-based benign lesions, including SH, SK, and cutaneous non-genital warts. The Company has commenced a controlled launch in these three regions with key opinion leaders in dermatology (Note 9). The Company was incorporated in Nevada on May 19, 2014. On June 18, 2018, the Company reincorporated from the State of Nevada to the State of Delaware. The Company is located in Hayward, California. The Company’s activities are subject to significant risks and uncertainties, including the need for additional capital. The Company has not yet commenced any revenue-generating operations, does not have any cash flows from operations, and will need to raise additional capital to finance its operations. However, there can be no assurances that the Company will be able to obtain additional financing on acceptable terms and in the amounts necessary to fully fund its operating requirements. |

Summary Of Significant Accounting Policies [Abstract] | |
Summary Of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared on a basis consistent with the Company’s December 31, 2020 audited Consolidated Financial Statements and include all adjustments, consisting of only normal recurring adjustments, necessary to fairly state the information set forth herein. The condensed consolidated financial statements have been prepared in accordance with the applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) and, as permitted by such rules and regulations, omit certain information and footnote disclosures necessary to present the financial statements in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). The condensed consolidated balance sheet as of December 31, 2020 was derived from the audited consolidated financial statements as of that date but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020. The results of operations for the three-month and six-month periods ended June 30, 2021 are not necessarily indicative of the results to be expected for the entire year or any future periods. Certain prior period balances have been reclassified to conform to the current period presentation in the consolidated financial statements and the accompanying notes. Sales and marketing expenses are reclassified out of general and administrative expenses, both of which are presented as separate line items. Amortization of intangible assets are reclassified to general and administrative expenses. Principles of Consolidation The accompanying condensed consolidated financial statements include the financial statements of Pulse Biosciences, Inc. and its wholly-owned subsidiaries. Intercompany balances and transactions, if any, have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires the Company to make estimates and assumptions that affect the amounts reported in the Financial Statements and accompanying notes to the condensed consolidated financial statements. Estimates include, but are not limited to, the valuation of cash equivalents and investments, the valuation and recognition of share-based compensation and the useful lives assigned to long-lived assets. The Company evaluates its estimates and assumptions based on historical experience and other factors and adjusts those estimates and assumptions when facts and circumstances dictate. Actual results could differ materially from these estimates. Significant Accounting Policies The Company’s significant accounting policies are described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020. The Company continually evaluates the accounting policies and estimates used in preparing the consolidated financial statements. During the six-month period ended June 30, 2021, the Company received 510(k) clearance, CE marking approval, and Health Canada clearance for their proprietary CellFX System and began to capitalize inventory in preparation for commercialization. Valuation of Inventory Inventory is stated at lower of cost or net realizable value. The Company establishes the inventory basis by determining the cost based on standard costs approximating the purchase costs on a first-in, first-out basis. Net realizable value is the estimated selling price in the ordinary course of the Company’s business, less reasonably predictable costs of completion, disposal, and transportation. The cost basis of the Company’s inventory will be reduced for any products that are considered excessive or obsolete based upon assumptions about future demand and market conditions. At June 30, 2021, there is no reduction to the balance of inventory for excessive and obsolete inventory. Net Loss per Share The Company calculates basic net loss per share by dividing net loss by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by giving effect to all potential dilutive common stock equivalents outstanding during the period. For purposes of this calculation, options to purchase common stock and common stock warrants are considered common stock equivalents. Potential common shares that have an anti-dilutive effect ( i.e ., those that increase income per share or decrease loss per share) are excluded from the calculation of diluted net loss per share. Basic and diluted net loss per common share is the same for all periods presented because all warrants, stock options and restricted stock units outstanding are anti-dilutive. The following outstanding stock options, warrants and restricted stock units were excluded from the computation of diluted net loss per share for the periods presented because including them would have had an anti-dilutive effect: Six-Month Periods Ended June 30, 2021 2020 Common stock warrants 600 809,418 Common stock options 5,827,524 5,216,500 Restricted stock units 89,273 34,402 Total 5,917,397 6,060,320 Recent Accounting Pronouncement In December 2019, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes , which eliminates certain exceptions related to the general principles in Accounting Standards Codification (ASC) 740 and makes amendments to other areas with the intention of simplifying various aspects related to accounting for income taxes. The new standard is effective for fiscal years beginning after December 15, 2020, including interim periods therein; with early adoption permitted. The Company adopted the Topic 740 effective January 1, 2021. The adoption did not have a material impact on the Company’s financial statements. |

Fair Value Of Financial Instruments [Abstract] | |
Fair Value Of Financial Instruments | 3. Fair Value of Financial Instruments The authoritative guidance with respect to fair value established a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three levels, and requires that assets and liabilities carried at fair value be classified and disclosed in one of three categories, as presented below. Level 1 - Observable inputs such as quoted prices in active markets for an identical asset or liability that the Company has the ability to access as of the measurement date. Financial assets and liabilities utilizing Level 1 inputs include money market funds. Level 2 - Inputs, other than quoted prices included within Level 1, which are directly observable for the asset or liability or indirectly observable through corroboration with observable market data. Financial assets and liabilities utilizing Level 2 inputs include commercial paper, corporate bonds, U.S. Treasury Securities, and asset-backed securities. Level 3 - Unobservable inputs for which there is little or no market data for the asset or liability which requires the reporting entity to develop its own assumptions. The Company did not classify any of its investments within Level 3 of the fair value hierarchy. The following table sets forth the fair value of the Company’s financial assets measured on a recurring basis as of June 30, 2021 and December 31, 2020, respectively (in thousands): June 30, 2021 December 31, 2020 Assets Classification Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Money market funds Cash and cash equivalents $ 44,279 $ — $ — $ 44,279 $ 7,176 $ — $ — $ 7,176 U.S. Treasury Securities Cash and cash equivalents — — — — — 2,004 — 2,004 U.S. Treasury Securities Investments — — — — — 8,012 — 8,012 Total assets measured at fair value $ 44,279 $ — $ — $ 44,279 $ 7,176 $ 10,016 $ — $ 17,192 The Company did no t have any financial liabilities measured on a recurring basis as of June 30, 2021 or December 31, 2020. During the six-month period ended June 30, 2021, there were no transfers between Level 1, Level 2 or Level 3 assets or liabilities reported at fair value on a recurring basis and the valuation techniques used did not change compared to the Company’s established practice. |

On December 31, 2020, the Company met the requirements for redemption of these warrants and delivered a notice of redemption to redeem all of the outstanding warrants that remained unexercised at February 5, 2021, for the redemption price of $ 0.01 per warrant. Pursuant to the redemption, the Company redeemed 5,139 warrants. Prior to the February 5, 2021 redemption date, 636,432 warrants were exercised, generating approximately $ 4.5 million of total gross proceeds to the Company. As of June 30, 2021, there were no Rights Offering Warrants outstanding . Equity Plans 2017 Equity Incentive Plan and 2017 Inducement Equity Incentive Plan The Board of Directors of the Company (the “Board”) previously adopted, and the Company’s stockholders approved, the Company’s 2017 Equity Incentive Plan (the “2017 Plan”). The 2017 Plan has a 10 -year term, and provides for the grant of stock options, stock appreciation rights, restricted stock, restricted stock units, performance units, and performance shares to employees, directors and consultants of the Company and any parent or subsidiary of the Company, as the Compensation Committee of the Board may determine. Subject to an annual evergreen increase and adjustment in the case of certain capitalization events, the Company initially reserved 1,500,000 shares of the Company’s common stock for issuance pursuant to awards under the 2017 Plan. In addition, shares remaining available under the Company’s 2015 Equity Incentive Plan, as amended (the “2015 Plan”), and shares reserved but not issued pursuant to outstanding equity awards that expire or terminate without being exercised or that are forfeited or repurchased by the Company will be added to the shares of common stock available for issuance under the 2017 Plan. The 2017 Plan is administered by the Board’s Compensation Committee. Effective January 1, 2021, the Company’s Board authorized an increase in the number of shares of common stock available under the 2017 Plan by 1,022,002 shares pursuant to the evergreen provision of the 2017 Plan. Pursuant to the 2017 Plan, the 2021 share increase is determined based on the least of (i) 1,200,000 shares, (ii) 4 % of the Company’s common stock outstanding at December 31 of the immediately preceding year, or (iii) such number of shares as determined by the Board. As of June 30, 2021, 634,902 shares of common stock remained available for issuance under the 2017 Plan. During November 2017, the Board adopted the 2017 Inducement Equity Incentive Plan (the “Inducement Plan”) and reserved 1,000,000 shares of the Company’s common stock for issuance pursuant to equity awards granted under the Inducement Plan. The Inducement Plan was adopted without stockholder approval. The Inducement Plan has a 10 -year term, and provides for the grant of equity-based awards, including nonstatutory stock options, restricted stock units, restricted stock, stock appreciation rights, performance shares and performance units, and its terms are substantially similar to the 2017 Plan, including with respect to treatment of equity awards in the event of a “merger” or “change in control” as defined under the Inducement Plan. Options issued under the Inducement Plan may have a term up to ten years and have variable vesting provisions. New hire grants generally vest 25 % per year starting upon the first anniversary of the grant. Equity-based awards issued under the Inducement Plan are only issuable to individuals not previously engaged as employees or as non-employee directors of the Company prior to the Inducement Plan’s adoption date. In May 2021, the Board approved an amendment to the Inducement Plan to reserve an additional 1,000,000 shares of the Company’s common stock for issuance pursuant to the Inducement Plan. As of June 30, 2021, 1,030,846 shares of common stock remained available for issuance under the Inducement Plan. Certain stock options awarded to the Company’s executives and other key employees contain performance conditions related to certain financial measures and achievements of strategic/operational milestones (performance options). As of June 30, 2021, not all of the performance conditions are probable to be achieved. Compensation expense has only been recognized for those conditions that are assumed to be probable. During February 2021, Management and the Compensation Committee approved of a modification to certain vesting conditions of outstanding performance options. The Company had no t recognized any compensation expense in relation to these performance options as the performance condition was previously deemed to be improbable. However, upon modification those specific performance conditions are now deemed probable and fully vested. As such, during the six-month period ended June 30, 2021, the full expense in relation to the amended performance conditions was recognized resulting in $ 4.2 million of additional stock-compensation expense. A summary of stock option activity under the 2015 Plan, 2017 Plan and Inducement Plan for the six-months ended June 30 , 2021 is presented below: Stock Options Outstanding Weighted Number average of shares exercise price Balances — December 31, 2020 5,039,194 $ 14.26 Options granted 976,078 Options exercised ( 44,981 ) Options canceled ( 80,029 ) Options expired ( 62,738 ) Balances — June 30, 2021 5,827,524 $ 15.64 Exercisable — June 30, 2021 3,042,982 $ 16.00 2017 Employee Stock Purchase Plan The Board previously adopted and the stockholders approved the Company’s 2017 Employee Stock Purchase Plan (the “2017 ESPP”). The 2017 ESPP is a broad-based plan that provides employees of the Company and its designated affiliates with the opportunity to become stockholders through periodic payroll deductions that are applied towards the purchase of Company common shares at a discount from the then-current market price. Subject to adjustment in the case of certain capitalization events, a total of 250,000 common shares of the Company were available for purchase at adoption of the 2017 ESPP. Pursuant to the 2017 ESPP, the annual share increase pursuant to the evergreen provision is determined based on the least of (i) 450,000 shares, (ii) 1.5 % of the Company’s common stock outstanding at December 31 of the immediately preceding year, or (iii) such number of shares as determined by the Board. Effective January 1, 2021, pursuant to the evergreen provision of the 2017 ESPP, the number of shares of common stock available under the 2017 ESPP was increased by 383,250 shares. During the six-month period ended June 30, 2021, the Company issued 66,525 shares of common stock under the 2017 ESPP. As of June 30, 2021, 673,949 shares of common stock remained available for issuance under the 2017 ESPP. Stock-based Compensation Total stock-based compensation expense consisted of the following (in thousands): Three-Month Periods Ended Six-Month Periods Ended June 30, June 30, 2021 2020 2021 2020 Research and development $ 1,002 $ 897 $ 4,168 $ 1,774 Sales and marketing 500 280 2,261 590 General and administrative 946 1,235 2,984 2,674 Total stock-based compensation expense $ 2,448 $ 2,412 $ 9,413 $ 5,038 The Company estimated the fair value of employee stock options on the grant date using the Black-Scholes option pricing model . The estimated fair value of employee stock options is amortized on a straight-line basis over the requisite service period of the awards. The Company reviews, and when deemed appropriate, updates the assumptions used on a periodic basis. Due to the limited trading history of the Company’s common stock, the Company utilizes a portfolio of comparable companies to estimate volatility.

Duggan, the Board Chairman, entered into a Loan Agreement in connection with Mr. Duggan lending the principal sum of $ 41.0 million to the Company. The Loan Agreement bore interest at a rate per annum equal to 5.0 %, payable quarterly commencing on July 1, 2021. The interest rate payable under the Loan Agreement increases to 7.0 % upon the occurrence of an Event of Default or a Material Adverse Effect, each as defined in the Loan Agreement. All unpaid principal amount of the Loan Agreement, together with any then unpaid and accrued interest, shall be payable at the earlier of (i) June 11, 2022 or (ii) when, upon the occurrence and during the continuance of an Event of Default, such amounts are declared due and payable by Mr. Duggan or made automatically due and payable, in each case, in accordance with the terms thereof, including any applicable cure periods as set forth in the Loan Agreement. A late payment fee equal to 2.0 % will be applied to any payments received later than one (1) business day after the expiration of the applicable cure period. Upon five business days prior written notice to Mr. Duggan, the Company may prepay all or any portion of the amounts borrowed under the Loan Agreement, without premium or penalty. The Loan Agreement subjects the Company to certain affirmative and negative covenants. In addition, the Loan Agreement contains certain Events of Default. During the six-month periods ended June 30, 2021, the Company recorded $ 0.6 million of interest expense in relation to this Loan Agreement. In June 2021, the Loan Agreement was terminated and $ 41.0 million principal, together with approximately $ 0.6 million of accrued and unpaid interest, was fully settled via issuance of the Company’s common stock at a price per share of $ 16.40 . Refer to Note 6 for additional details of the private placement sale. Insurance Loan Agreement On May 13, 2021, the Company secured its annual director and officer liability insurance policy. The total premiums for the policy are approximately $ 2.6 million, of which the Company made a down payment of $ 0.7 million and financed the balance of $ 1.9 million via an Insurance Loan Agreement. The Insurance Loan Agreement has an annual interest rate of 3.69 % and requires monthly payments through February 2022, upon which the Insurance Loan Agreement will be paid in full. The outstanding principal portion of the Insurance Loan Agreement, together with any accrued and unpaid interest, is recorded as a note payable in the balance sheet. Operating Leases In January 2017, the Company entered into a five-year lease (the “Existing Lease”) for approximately 15,700 square feet for its corporate headquarters located in Hayward, California. The lease commenced in July 2017. In May 2019, the Company entered into Lease Amendment 1 (the “Lease Amendment”) in relation to the Existing Lease and added the lease of new premises of approximately 13,300 square feet and 21,300 square feet, (Expansion Premises 1 and Expansion Premises 2, respectively). Additionally, the term of the Existing Lease was extended to be coterminous with Expansion Premises 1 and Expansion Premises 2, effective October 2029. The Company evaluated the lease amendment under the provisions of ASC 842. It concluded that the Lease Amendment would be accounted for as a single contract with the Existing Lease because the additional lease payments due to the Lease Amendment was not commensurate with the right-of-use (the “ROU”) asset granted to the Company. Though the Lease Amendment was accounted for as a single contract, the Existing Premises, Expansion Premises 1 (occupied in November 2019) and Expansion Premises 2 (occupied in May 2020) are accounted for as separate lease components. Accordingly, the Company measured and allocated consideration to each lease component as of the modification date. Information related to the Compan y’s ROU assets and related lease liabilities are as follows (in thousands, except for remaining lease term and discount rate): Year Ending December 31: 2021 (remaining 6 months) $ 894 2022 1,806 2023 1,845 2024 1,910 2025 1,976 2026 2,046 Thereafter 6,191 Total lease payments 16,668 Less imputed interest ( 5,504 ) Total lease liabilities $ 11,164 Other supplemental information: Current operating lease liabilities $ 719 Non-current operating lease liabilities 10,445 Total lease liabilities $ 11,164 Cash paid for operating lease liabilities $ 749 Weighted average remaining lease term 8.34 Weighted average discount rate 10 % Rent expense, including common area maintenance charges, was $ 0.5 million for each of the three-month periods ended June 30 , 2021 and 2020; and was approximately $ 1.0 million and $ 0.7 million during the six-month periods ended June 30, 2021 and 2020, respectively. Legal Proceedings The Company maintains indemnification agreements with its directors and officers that may require the Company to indemnify them against liabilities that arise by reason of their status or service as directors or officers, except as prohibited by applicable law. From time to time, the Company may be involved in a variety of claims, lawsuits, investigations, and proceedings relating to securities laws, product liability, patent infringement, contract disputes, and other matters relating to various claims that arise in the normal course of the Company’s business. The Company currently believes that these ordinary course matters are not material to the condensed consolidated financial statements of the business; however, the results of litigation and claims are inherently unpredictable. |

Controlled Launch [Abstract] | |
Controlled Launch | 9. Controlled Launch In February 2021, the Company received 510(k) clearance from the U.S. FDA for its proprietary CellFX System with initial clearance for a general dermatologic indication. In January 2021, the Company received CE marking approval for the CellFX System, which allows for marketing of the system in the EU for treatment of general dermatologic conditions, including SH, SK, and cutaneous non-genital warts. Additionally, in June 2021 the Company received Health Canada approval for the CellFX System, which allows for marketing of the system in Canada for use in dermatological procedures requiring ablation and resurfacing of the skin for the reduction, removal, and/or clearance of cellular-based benign lesions. Having obtained clearance in these three regions, the Company has commenced a controlled launch of the CellFX System in the U.S., EU, and Canada via their CellFX Expectations Excelled Program (the Program). The Company selected a total of approximately 80 key opinion leaders in dermatology across the U.S., EU and Canada to be the first physicians (consultants) to launch the CellFX System and the associated CellFX commercial procedures into their respective markets and geographies. The Company has executed consulting agreements to retain these key opinion leaders to participate in the Program. According to the Program plan, the Company provides and sets-up the CellFX System at each consultant’s site and provides the consultant with the necessary related products and components, free of charge, to complete the requirements of the Program. Each CellFX System and any un-used component products remain the property of the Company throughout the Program. The consultant identifies and recruits up to 40 or 50 patients, dependent on the contract, for participation in the Program, performing the CellFX procedure on each of the appropriately selected patients. Under the program, the key opinion leader consultants and their patients complete evaluation surveys about their experiences with the CellFX System and provide other information helpful to the Company. Upon completion of the procedures and the survey feedback, the consultants earn either credits which can be used towards the future purchase of the CellFX System or, in some jurisdictions, fair payment for their time and effort completing the paperwork required under the Program. Credits earned and, if applicable, any other payments earned are limited to a maximum amount dependent on number of patient procedures performed. Upon completion of the maximum number of patient procedures, the consultant may choose to either enter into a purchase agreement with the Company, where they may use the credits earned (or other payments earned, as applicable) towards purchase of the CellFX System, or they shall return the CellFX System to the Company. As patient procedures and surveys have been completed under the Program, the Company has been accruing for the value of the credits earned, which have been recorded in accrued expenses, with a corresponding charge to marketing expense. During the three-month and six-month periods ended June 30, 2021, the Company recorded $ 0.4 million and $ 0.6 million, respectively, of sales and marketing expense in relation to the Program. |

The Company evaluates its estimates and assumptions based on historical experience and other factors and adjusts those estimates and assumptions when facts and circumstances dictate. Actual results could differ materially from these estimates. |
Significant Accounting Policies | Significant Accounting Policies The Company’s significant accounting policies are described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020. The Company continually evaluates the accounting policies and estimates used in preparing the consolidated financial statements. During the six-month period ended June 30, 2021, the Company received 510(k) clearance, CE marking approval, and Health Canada clearance for their proprietary CellFX System and began to capitalize inventory in preparation for commercialization. |
Valuation Of Inventory | Valuation of Inventory Inventory is stated at lower of cost or net realizable value. The Company establishes the inventory basis by determining the cost based on standard costs approximating the purchase costs on a first-in, first-out basis. Net realizable value is the estimated selling price in the ordinary course of the Company’s business, less reasonably predictable costs of completion, disposal, and transportation. The cost basis of the Company’s inventory will be reduced for any products that are considered excessive or obsolete based upon assumptions about future demand and market conditions. At June 30, 2021, there is no reduction to the balance of inventory for excessive and obsolete inventory. |
Net Loss Per Share | Net Loss per Share The Company calculates basic net loss per share by dividing net loss by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by giving effect to all potential dilutive common stock equivalents outstanding during the period. For purposes of this calculation, options to purchase common stock and common stock warrants are considered common stock equivalents. Potential common shares that have an anti-dilutive effect ( i.e ., those that increase income per share or decrease loss per share) are excluded from the calculation of diluted net loss per share. Basic and diluted net loss per common share is the same for all periods presented because all warrants, stock options and restricted stock units outstanding are anti-dilutive. The following outstanding stock options, warrants and restricted stock units were excluded from the computation of diluted net loss per share for the periods presented because including them would have had an anti-dilutive effect: Six-Month Periods Ended June 30, 2021 2020 Common stock warrants 600 809,418 Common stock options 5,827,524 5,216,500 Restricted stock units 89,273 34,402 Total 5,917,397 6,060,320 |
Recent Accounting Pronouncement | Recent Accounting Pronouncement In December 2019, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes , which eliminates certain exceptions related to the general principles in Accounting Standards Codification (ASC) 740 and makes amendments to other areas with the intention of simplifying various aspects related to accounting for income taxes. The new standard is effective for fiscal years beginning after December 15, 2020, including interim periods therein; with early adoption permitted. The Company adopted the Topic 740 effective January 1, 2021. The adoption did not have a material impact on the Company’s financial statements. |
