Medtronic plc received U.S. FDA premarket approval of its Diamondtemp Ablation (DTA) system for treatment of patients with recurrent, symptomatic paroxysmal atrial fibrillation. The temperature-controlled radiofrequency (RF) ablation system features industrial-grade diamonds, which provide 200 to 400 times the thermal conductivity seen in conventional ablation and enable more efficient delivery of energy to regions of the heart responsible for the erratic electrical signals underlying atrial fibrillation (AF).
The U.S. Centers for Medicare & Medicaid Services (CMS) had packaged a proposal to redefine the term “reasonable and necessary” along with the proposal to cover FDA-designated breakthrough devices, but ultimately punted on the definitional question until the end of this year. Mark Leahey, president and CEO of the Medical Device Manufacturers Association (MDMA), told BioWorld that it may be just as well that the agency didn’t expeditiously push through the reasonable and necessary question because of the enormous complexity of the proposal.
Boston Scientific Corp. has received the U.S. FDA’s nod for its Synergy Megatron drug-eluting stent (DES) system. The company said the premarket approval makes Synergy Megatron the first platform in the U.S. that is designed for large, proximal vessels. The Synergy Megatron biopolymer (BP) stent is indicated “for improving coronary artery luminal diameter in patients with symptomatic ischemic heart disease, stable or unstable angina, non-ST elevation myocardial infarction or documented silent ischemia due to atherosclerotic lesions in native coronary arteries.

Triggering a wave of commentary over its import, Biogen Inc. on Jan. 29 said the FDA has extended to June 7 its review of a BLA for the experimental Alzheimer's disease therapy aducanumab after the company submitted additional analyses and clinical data, making for a major amendment to the application. The three-month delay, from an earlier assigned PDUFA date of March 7, followed a thumbs-down vote by agency advisors in November. It sparked both sunny optimism and a bit of pessimism about the program's prospects on Friday.

The SARS-CoV-2 virus has now had ample time to mutate, as reports of the proliferation of multiple variants make clear, and the U.S. FDA’s Tim Stenzel said the agency is now focused on three variants, including one recently reported from Israel. Stenzel said on the latest COVID-19 testing town hall that one of the key concerns regarding existing authorized tests is the potential for loss of sensitivity, a problem the agency hopes to overcome without the use of live virus.
The U.S. biosimilar market is coming of age under the BsUFA II agreement, but there are a few steps the FDA could take to help it develop more predictably. For starters, the agency should conduct pre-approval inspections earlier in the 12-month biosimilar review cycle to give sponsors time to address unexpected issues, industry representatives told the FDA Jan. 27 in response to an independent interim assessment of the enhanced transparency and communication processes included in the current user fee agreement.
Health care professionals (HCPs) might prefer a new respirator for each shift, but the ongoing shortage has left clinical sites with a need to employ dry heat for filtering facepiece respirator reuse. The U.S. FDA said on a Jan. 26 town hall that it will stick to an established policy that these devices can be processed with dry heat no more than five times, a practice that is likely to stick for the foreseeable future despite that administrators are required to provide fresh units when possible.
Orthospin Ltd.'s outlook was braced by the U.S. FDA's 510(k) clearance of its next-generation digitally enabled, robotic external fixation system.
