• Compelling Cardiac Catheter Data

  The nPulse Cardiac Catheter System demonstrated 96% procedural success at one year in a first-in-human clinical study for atrial fibrillation treatment, with average procedure times of approximately 65 minutes. This data was presented in February 2026, elaborating on the positive clinical data previously announced on February 6, 2026.

• Pivotal Trial Approvals for Cardiac Devices

  FDA Investigational Device Exemption (IDE) approvals were received in September 2025 for a pivotal clinical trial of the nPulse Cardiac Surgical Clamp and in December 2025 for a pivotal trial of the nPulse Cardiac Catheter System, marking significant progress towards commercialization.

• FDA Breakthrough Device Designation

  The nPulse Cardiac Surgery System received FDA Breakthrough Device Designation in July 2024 and was enrolled in the FDA's Total Product Life Cycle (TPLC) Advisory Program, aiming to expedite its development and review for atrial fibrillation treatment.

• First Commercial Product Revenue

  The company generated its first product revenue of $0.4 million in 2025 from the limited market release of the Vybrance Percutaneous Electrode System, following FDA 510(k) clearance in March 2024.

This annual report provides a comprehensive update on Pulse Biosciences' strategic shift to cardiology and soft tissue ablation, revealing highly positive clinical and regulatory milestones that significantly de-risk its core product pipeline. The reported 96% procedural success rate at one year for the nPulse Cardiac Catheter in treating atrial fibrillation, coupled with efficient procedure times, is a compelling indicator of its disruptive market potential. The FDA's Breakthrough Device Designation and enrollment in the TPLC Advisory Program for the cardiac surgical system, along with IDE approvals for pivotal trials for both cardiac devices, underscore the regulatory momentum and potential for expedited market access. While the company experienced increased net losses and cash burn in 2025, reflecting substantial investments in R&D and commercialization, the initial $0.4 million in product revenue from the Vybrance system marks a crucial step towards commercial viability. The company explicitly states a need for additional financing, but the strong clinical data and regulatory progress significantly enhance its position to secure future capital. Investors should view this report as a strong validation of the company's technology and a positive step towards commercialization in large, growing markets, despite the continued financial losses typical of a development-stage medical device company.
