Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block] | Note 1. Description of the Business Pulse Biosciences, Inc. is a novel ablation company committed to health innovation using its patented Nano-pulse Stimulation (“NPS”) technology, a revolutionary energy modality that delivers nanosecond-duration pulses of electrical energy, each less than a millionth of a second long, to nonthermally clear or kill targeted cells. NPS technology, also referred to as a Nanosecond Pulsed-Field Ablation (“nsPFA”) energy when used to ablate cellular tissue, can be used to treat a variety of medical conditions for which an optimal solution remains unfulfilled. The Company developed its proprietary nPulse System (formerly known as CellFX), a novel nsPFA delivery platform, and commercialized the initial application of its nsPFA energy to treat benign lesions of the skin and in parallel, designed a variety of applicators, or disposables, to explore the potential use of the nPulse platform in other medical specialties. Based on its preclinical experience and the potential to significantly improve outcomes for patients in a large and growing market, the Company decided to focus its primary efforts on the use of nsPFA energy and the nPulse platform in the treatment of atrial fibrillation (“AF”), and in a select few other markets where it could have a profound positive impact on healthcare for both patients and providers, such as surgical soft tissue ablation. The Company is incorporated in the State of Delaware. It is located in Miami, Florida and continues to maintain its offices in Hayward, California. The Company maintains its website at www.pulsebiosciences.com where general information about the Company is available. Liquidity and Capital Resources The Company has incurred net operating losses and negative cash flows from operations since its inception and had an accumulated deficit of $481.9 million as of March 31, 2026. As of March 31, 2026, the Company had cash and cash equivalents of $68.3 million. The Company believes that the existing financial resources combined with the net proceeds received from the shares of common stock sold on May 11, 2026 (see Note 9. Subsequent Events) are sufficient to continue operating activities for at least one year past the issuance date of these condensed consolidated financial statements. The Company has historically financed its operations primarily through the sale of common stock and debt. To date, the Company has generated limited revenue from product sales and has incurred significant operating losses in each year since inception. The Company may continue to incur additional losses for the next several years. While the Company has been able to raise multiple rounds of financing, there can be no assurance that in the event the Company requires additional financing, such financing will be available on terms which are favorable or at all. Failure to raise sufficient capital when needed or generate sufficient cash flow from operations would impact the ability to pursue business strategies and could require the Company to delay, scale back or discontinue one or more product development programs, or other aspects of the Company's business objectives.
