Neuroone Medical Technologies Corp. expanded into treatment of chronic pain with a new U.S. FDA clearance for use of its Onerf system to treat trigeminal nerve pain. The system uses radiofrequency ablation to disrupt pain signals from the nerve to the brain.

Since the U.S. FDA’s approval of the first pulsed field ablation (PFA) system in the U.S. last December, PFA technology has rapidly reconfigured the electrophysiology market in the U.S. and ramped up sales of PFA systems in Europe.

Haemonetics Corp. appears ready to make a bit of a retro investment, as it entered into a definitive agreement to acquire Advanced Cooling Therapy Inc. (dba Attune Medical) for $160 million at closing plus undisclosed additional contingent payments. Attune manufactures the U.S. FDA-cleared Ensoetm device, which cools the esophagus during radiofrequency cardiac ablation procedures, a treatment for atrial fibrillation whose days appeared numbered.

Continuing the spate of regulatory approvals for pulsed field ablation (PFA) devices around the world, Johnson & Johnson’s Biosense Webster Inc. unit secured CE mark for the Varipulse platform for treatment of symptomatic, drug-refractory recurrent paroxysmal atrial fibrillation.

Argá Medtech SA said patients in the first stage of enrollment for a first-in-human clinical trial have been safely and effectively treated with an ablation system for treating atrial fibrillation (AF). The Coherent Sine Burst Electroporation (CSE) system uses a pulsed field ablation (PFA) sine waveform and single, configurable (circular, linear, and focal) ablation catheter to better treat patients suffering from AF.

Acotec Scientific Holdings Ltd. has received marketing approval for its radiofrequency ablation system from China’s NMPA to treat varicose veins. The radiofrequency ablation system consists of an endovenous radiofrequency catheter and a radiofrequency generator.
