Medtronic plc and Irvine, Calif.-based Axonics Inc. have been locked in a struggle over several patents in the past few years, but now Medtronic has shifted some of its effort from the U.S. courts to the executive branch.

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.

The U.S. FDA granted Virtual Incision Corp. de novo marketing authorization for its miniaturized in vivo robotic assistant for use in colectomy procedures in adults. The two-pound device offers portability and quick setup, eliminating the need for specialized operating rooms or arrangements to accommodate robotics.

Boston Scientific Corp. notched another win with the U.S. FDA approval of its spinal cord stimulator (SCS), Wavewriter, for treatment of non-surgical back pain just a week after receiving the agency’s nod for its Farapulse pulsed field ablation system. The new indication comes four months after expansion of approved uses for Wavewriter to include painful diabetic peripheral neuropathy.

Cyted Ltd. received U.S. FDA 510(k) clearance for its Endosign capsule technology, a non-endoscopic capsule sponge device used to collect pan-esophageal samples to detect esophageal pre-cancer and other conditions.

Two other PFA devices scored regulatory wins since the new year: Biosense Webster inc.’s Varipulse secured approval from the Japanese Ministry of Health Labor and Welfare and Sichaun Jinjiang Electronic Medical Device Technology Co. Ltd. got the nod from China’s National Medical Products Administration.

Abbott Laboratories received U.S. FDA approval for its Liberta RC deep brain stimulation (DBS) system for use in movement disorders, less than two weeks after the agency gave its nod to Medtronic’s Percept RC DBS system. The news come on the heels of Abbott’s release of strong fourth quarter results on Wednesday.
