ALEXANDRIA, Va., July 23 -- United States Patent no. 12,364,535, issued on July 22, was assigned to AFFERA INC. (Watertown, Mass.).

"Pulsed radiofrequency ablation" was invented by Doron Harlev (Brookline, Mass.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Ablation systems and methods of the present disclosure are directed toward delivering pulsed radiofrequency (RF) energy to target tissue. The pulsations of the RF energy, combined with cooling at a surface of the target tissue, can advantageously promote local heat transfer in the target tissue to form lesions having dimensions larger than those that can be safely formed in tissue using non-pulsed RF energy under similar conditions."
