Description Of The Business [Abstract]
Description Of The Business	1. Description of the Business Pulse Biosciences, Inc., incorporated in Nevada on May 19, 2014 , is a clinical-stage medical technologies company developing commercial clinical applications for its proprietary Nano-Pulse Stimulation (“NPS”) technology. NPS is a novel patented technology that leverages nano-second duration energy pulses that have demonstrated effective local tumor control and the initiation of an adaptive immune response in pre-clinical studies. The Company is pursuing a number of potential clinical applications for NPS, including oncology, dermatology, aesthetics and other minimally invasive applications where the Company believes NPS may provide greater benefits compared to current therapies and treatments. The Company’s corporate office and research facility are 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 In the opinion of the Company’s management, the accompanying unaudited Condensed Consolidated Financial Statements (“Financial Statements”) have been prepared on a consistent basis with the Company’s December 31, 2016 audited Consolidated Financial Statements and include all adjustments, consisting of only normal recurring adjustments, necessary to fairly state the information set forth herein. The Financial Statements have been prepared in accordance with the applicable rules and regulations of the Securities and Exchange Commission 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, 2016 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 completed financial statements. These Financial Statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended December 31, 2016 included in the Company’s Annual Report on Form 10-K, filed on March 20, 2017 . The results of operations for the three-month and six-month period s ended June 30 , 2017 are not necessarily indicative of the results to be expected for the entire year or any future periods. 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 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. Actual results could differ materially from these estimates. Significant Accounting Policies There have been no material changes to the Company’s significant accounting policies during the six -month period ended June 30 , 2017, as compared to the significant accounting policies described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 .   Principles of Consolidation The accompanying consolidated financial statements include the financial statements of Pulse and its wholly-owned subsidiaries. Intercompany balances and transactions, if any, have been eliminated in consolidation. Net Loss per Share The Company’s basic net loss per share is calculated by dividing the net loss by the weighted average number of shares of common stock outstanding for the period. Diluted net loss per share is computed by giving effect to all potential dilutive common stock equivalents outstanding for 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 and stock options outstanding are anti-dilutive. The following outstanding stock options and warrants to purchase common stock 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,  2017 2016  Common stock warrants 705,121 874,610  Common stock options 2,227,676 1,020,568  Restricted stock units 160,974 —  Total 3,093,771 1,895,178     Reclassification Certain items in the prior period financial statements have been reclassified to conform to current period financial statements. Recent Accounting Pronouncements Recently Adopted Accounting Standards During March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-09, Improvements to Employee Share-based Payment Accounting . This ASU simplifies the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This ASU requires that excess tax benefits and deficiencies be recognized as income tax benefit or expense in the income statement. The Company adopted this ASU as of January 1, 2017. The adoption of this ASU did not have a significant impact on the Company’s financial position. Recently Issued Accounting Standards During May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers . This updated standard will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective and permits the use of either the retrospective or cumulative effect transition method. In August 2015, the FASB issued an update to defer the effective date of this update by one year. This updated standard becomes effective for the Company in the first quarter of fiscal year 2018 . The Company is currently evaluating the impact of adopting these standards. During February 2016, the FASB issued ASU No. 2016-02, Leases , which amends the existing accounting standards for leases. The new standard requires lessees to record a right-of-use asset and a corresponding lease liability on the balance sheet (with the exception of short-term leases). For lessees, leases will continue to be classified as either operating or financing in the income statement. This ASU becomes effective for the Company in the first quarter of fiscal year 2019 and early adoption is permitted. This ASU is required to be applied with a modified retrospective approach and requires application of the new standard at the beginning of the earliest comparative period presented. The Company generally does not finance purchases of equipment or other capital, but does lease its facilities. While the Company is continuing to assess all potential impacts of this standard, it expects that most of its lease commitments will be subject to the updated standard and recognized as lease liabilities and right-of-use assets upon adoption. During June 2016, the FASB issued ASU 2016-13, Financial Instruments — Measurement of Credit Losses on Financial Instruments , which requires measurement and recognition of expected credit losses for financial assets held. ASU 2016-13 is effective for the Company beginning January 1, 2020. The Company is currently evaluating the impact of adopting this standard. During January 2017, the FASB issued ASU 2017-04, Intangibles — Goodwill and Other (Topic 350): Simplifying the Accounting for Goodwill Impairment , which simplifies the accounting for goodwill impairment. This ASU removes Step 2 of the goodwill impairment test, which requires hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The new guidance also requires disclosure of the amount of goodwill at reporting units with zero or negative carrying amounts. ASU 2017-04 is effective for the Company beginning January 1, 2020. Early adoption is permitted for any impairment tests performed after January 1, 2017. The Company is currently evaluating the impact of adopting such standard.

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 active-exchange traded securities and exchange-based derivatives. 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 fixed income securities, non-exchange based derivatives, mutual funds, and fair-value hedges. Level 3 - Unobservable inputs in which there is little or no market data for the asset or liability which requires the reporting entity to develop its own assumptions. Financial assets and liabilities utilizing Level 3 inputs include infrequently-traded, non- exchange -based derivatives and commingled investment funds, and are measured using present value pricing models. The Company determines the level in the fair value hierarchy within which each fair value measurement falls in its entirety, based on the lowest level input that is significant to the fair value measurement in its entirety. In determining the appropriate levels, the Company performs an analysis of the assets and liabilities at each reporting period end. The Company classifies its Level 2 instruments based on market pricing and other observable inputs. 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 , 2017 and December 31, 2016, respectively (in thousands):    June 30, 2017 December 31, 2016  Assets Classification Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total  Money market funds Cash and cash equivalents $ 1,708 $ — $ — $ 1,708 $ 1,726 $ — $ — $ 1,726  Corporate bonds Investments — 11,901 — 11,901 — 13,289 — 13,289  Asset-backed security Investments — 1,508 — 1,508 — 1,017 — 1,017  Total assets measured at fair value $ 1,708 $ 13,409 $ — $ 15,117 $ 1,726 $ 14,306 $ — $ 16,032  The Company did not have any financial liabilities measured on a recurring basis as of June 30 , 2017 or December 31, 2016. During the six -month period ended June 30 , 2017, 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.

Stockholders' Equity And Stock-Based Compensation	7 . Stockholders’ Equity and Stock-Based Compensation  Private Placement On February 7, 2017, the Company entered into a securities purchase agreement with Robert W. Duggan and Maky Zanganeh (the “Investors”), pursuant to which the Company, in a private placement, issue d and sold to the Investors an aggregate of 819,673 shares of the Company’s common stock, par value $0.001 per share, at a price per share of $6.10 , for net proceeds of approximately $4,965,000 . Warrants During the six months ended June 30, 2017, warrants to purchase 169,489 shares of common stock were either cash or net exercised, resulting in the issuance of approximately 136,552 shares of common stock. As of June 30, 2017, 705,121 warrants remained outstanding. Equity Plans 2017 Equity Incentive Plan The Board of Directors (the “Board”) of the Company previously adopted, subject to stockholder approval, the Company’s 2017 Equity Incentive Plan (the “2017 Plan”). The Company’s stockholders approved the 2017 Plan at the annual meeting of stockholders held on May 16, 2017 (the “Annual Meeting”). 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 of Directors may determine. Subject to an annual evergreen increase and adjustment in the case of certain capitalization events, 1,500,000 shares of our common stock are authorized for issuance pursuant to awards under the 2017 Plan. In addition, shares remaining available under our 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.  2017 Employee Stock Purchase Plan The Board of the Company previously adopted, subject to stockholder approval, the Company’s 2017 Employee Stock Purchase Plan (the “2017 ESPP”). At the Annual Meeting, the stockholders approved 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 are available for purchase under the 2017 ESPP. As of June 30, 2017 , the Company had three active equity compensation plan s , the outstanding shares under the 2015 Plan, the 201 7 Plan and the 2017 ESPP .

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. The fair value of employee stock options was estimated using the following weighted - average assumptions:     Three-Month Periods Ended June 30, Six-Month Periods Ended June 30,  2017 2016 2017 2016  Expected term in years 5.3 - 6.1 6.1 5.3 - 6.1 6.1  Expected volatility 80% 80% 80% 80%  Risk-free interest rate 1.9 - 2.0% 1.31% 1.9 - 2.1% 1.39%  Dividend yield — — — —  The Company granted stock options to a non-employee during the six-month period ended June 30, 2017. The Company uses the Black-Scholes option-pricing model to estimate the fair value of awards granted to nonemployees. The measurement of stock-based compensation for nonemployees is subject to periodic adjustments as the underlying equity instruments vest, and the resulting change in value, if any, is recognized in the Company’s consolidated statements of operations during the period the related services are rendered. The fair value of a nonemployee stock option during the six-month period ended June 30, 2017 was estimated using the following assumptions: expected term: 9.9 years; expected volatility: 80% ; risk-free interest rate: 2.4% ; and dividend yield: none . The Company did not grant any stock options to non-employees during the three-month period ended June 30, 2017.  The Company estimated the fair value of ESPP on the grant date using the Black-Scholes option pricing model . The estimated fair value of ESPP 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.

As of December 31, 2016, the lease obligations for less than one year, one to three years, three to five years and more than five years is approximately $0.3 million, $1.1 million, $1.1 million and $0.3 million, respectively. During the three-month periods ended June 30, 2017 and 2016, rent exp ense, including common area maintenance charges, was approximately $74,000 and $49,000 , respectively .

Summary Of Significant Accounting Policies [Abstract]
Basis Of Presentation	Basis of Presentation In the opinion of the Company’s management, the accompanying unaudited Condensed Consolidated Financial Statements (“Financial Statements”) have been prepared on a consistent basis with the Company’s December 31, 2016 audited Consolidated Financial Statements and include all adjustments, consisting of only normal recurring adjustments, necessary to fairly state the information set forth herein. The Financial Statements have been prepared in accordance with the applicable rules and regulations of the Securities and Exchange Commission 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, 2016 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 completed financial statements. These Financial Statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended December 31, 2016 included in the Company’s Annual Report on Form 10-K, filed on March 20, 2017 . The results of operations for the three-month and six-month period s ended June 30 , 2017 are not necessarily indicative of the results to be expected for the entire year or any future periods.
Use Of Estimates	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 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. Actual results could differ materially from these estimates.
Significant Accounting Policies	Significant Accounting Policies There have been no material changes to the Company’s significant accounting policies during the six -month period ended June 30 , 2017, as compared to the significant accounting policies described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 .
Principles of Consolidation	Principles of Consolidation The accompanying consolidated financial statements include the financial statements of Pulse and its wholly-owned subsidiaries. Intercompany balances and transactions, if any, have been eliminated in consolidation.
Net Loss Per Share	Net Loss per Share The Company’s basic net loss per share is calculated by dividing the net loss by the weighted average number of shares of common stock outstanding for the period. Diluted net loss per share is computed by giving effect to all potential dilutive common stock equivalents outstanding for 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 and stock options outstanding are anti-dilutive. The following outstanding stock options and warrants to purchase common stock 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,  2017 2016  Common stock warrants 705,121 874,610  Common stock options 2,227,676 1,020,568  Restricted stock units 160,974 —  Total 3,093,771 1,895,178    
Reclassification	Reclassification Certain items in the prior period financial statements have been reclassified to conform to current period financial statements.
Recent Accounting Standards	Recent Accounting Pronouncements Recently Adopted Accounting Standards During March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-09, Improvements to Employee Share-based Payment Accounting . This ASU simplifies the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This ASU requires that excess tax benefits and deficiencies be recognized as income tax benefit or expense in the income statement. The Company adopted this ASU as of January 1, 2017. The adoption of this ASU did not have a significant impact on the Company’s financial position. Recently Issued Accounting Standards During May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers . This updated standard will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective and permits the use of either the retrospective or cumulative effect transition method. In August 2015, the FASB issued an update to defer the effective date of this update by one year. This updated standard becomes effective for the Company in the first quarter of fiscal year 2018 . The Company is currently evaluating the impact of adopting these standards. During February 2016, the FASB issued ASU No. 2016-02, Leases , which amends the existing accounting standards for leases. The new standard requires lessees to record a right-of-use asset and a corresponding lease liability on the balance sheet (with the exception of short-term leases). For lessees, leases will continue to be classified as either operating or financing in the income statement. This ASU becomes effective for the Company in the first quarter of fiscal year 2019 and early adoption is permitted. This ASU is required to be applied with a modified retrospective approach and requires application of the new standard at the beginning of the earliest comparative period presented. The Company generally does not finance purchases of equipment or other capital, but does lease its facilities. While the Company is continuing to assess all potential impacts of this standard, it expects that most of its lease commitments will be subject to the updated standard and recognized as lease liabilities and right-of-use assets upon adoption. During June 2016, the FASB issued ASU 2016-13, Financial Instruments — Measurement of Credit Losses on Financial Instruments , which requires measurement and recognition of expected credit losses for financial assets held. ASU 2016-13 is effective for the Company beginning January 1, 2020. The Company is currently evaluating the impact of adopting this standard. During January 2017, the FASB issued ASU 2017-04, Intangibles — Goodwill and Other (Topic 350): Simplifying the Accounting for Goodwill Impairment , which simplifies the accounting for goodwill impairment. This ASU removes Step 2 of the goodwill impairment test, which requires hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The new guidance also requires disclosure of the amount of goodwill at reporting units with zero or negative carrying amounts. ASU 2017-04 is effective for the Company beginning January 1, 2020. Early adoption is permitted for any impairment tests performed after January 1, 2017. The Company is currently evaluating the impact of adopting such standard.
