Exhibit 99.1

IceCure Granted Notice of Allowance for U.S.Patent for its Next-Generation XSense™ Cryoprobes

The invention is designed to improve cryoprobeextraction, further reducing risk of tissue trauma, leading to lower costs and improved patient experience

XSense™ System with Cryoprobes recentlyreceived regulatory approval in the U.S. and Israel

CAESAREA, Israel, September 18, 2025 – IceCure Medical Ltd. (Nasdaq: ICCM) (“IceCure”, “IceCure Medical” or the “Company”), developer of minimally-invasive cryoablation technology that destroys tumors by freezing as an option to surgical tumor removal, today announced it has received a Notice of Allowance from the U.S. Patent and Trademark Office for its patent titled “Cryoprobe”.

“Our industry-leading liquid-nitrogen-based cryoablation platform has been further advanced with this latest invention, a cryoprobe technology,” stated IceCure’s Chief Executive Officer, Eyal Shamir. “There is an abundance of data, much of it from independent studies, showing that minimally invasive cryoablation procedures with our flagship ProSense® system have resulted in an improved patient experience with excellent medical outcomes. This new cryoprobe technology, which is integrated in our next-generation XSense™ system, further reduces any potential risk of tissue trauma as the cryoprobe is extracted from the patient at the end of the short, minimally invasive outpatient procedure.”

This invention introduces a novel method for safely and efficiently extracting the cryoprobe after tissue freezing during cryoablation procedures. The cryoprobe’s tip is integrated with a heater, temperature sensor, and controlled gas pulses, enabling precise estimation and management of the cryoprobe’s external surface temperature—even while embedded in frozen tissue. Designed to be compatible with a wide range of XSense™ system cryoprobe types, the new cryoprobe technology is a versatile solution for multiple clinical scenarios.
