Pulse Biosciences’ First Study in a Surgical Application of Nanosecond Pulsed Field Ablation (nsPFA) Technology to be Featured in Two Poster Presentations at the American Thyroid Association Annual Meeting

First prospective clinical feasibility study suggests nsPFA may be a safe and effective method for treating benign thyroid tumors or nodules

Pulse Biosciences, Inc. (Nasdaq: PLSE, “the Company”), a company primarily focused on leveraging its novel and proprietary Nanosecond Pulsed Field Ablation (nsPFA) technology for the treatment of atrial fibrillation, today announced its nsPFA technology will be featured in two poster presentations at the upcoming American Thyroid Association 2023 Annual Meeting in Washington D.C. from September 27th to October 1st, 2023.

“I am proud to have been a part of the first human surgical procedure study on benign thyroid nodules conducted with the nsPFA technology. In the treated regions, we observed complete ablation of the cellular tissue without evidence of thermal necrosis or damage to noncellular structures, as is typically the case with current thermal treatment modalities,” said Dr. Stefano Spiezia, Chief of Endocrine Surgery Division at Napoli Ospedale del Mare and principal investigator of the study. “We look forward to sharing these promising results with our esteemed colleagues at the ATA meeting and continuing our work with nsPFA.”

“The findings from this study are extremely compelling and suggest that nsPFA could represent a significant advancement in the treatment of symptomatic benign thyroid nodules,” said Dr. Ralph Tufano, Director of Head and Neck Endocrine Surgery at Sarasota Memorial Health Care System. “The exciting possibility of a new energy modality with improved speed and safety around critical structures, such as nerves and blood vessels, could be a game-changer for many of these patients."
