The U.S. FDA has granted premarket approval for Transmedics Group Inc.’s OCS heart system for use with organs from donors after circulatory death (DCD). The approval expands on a prior FDA approval of the device for use with organs from donors after brain death in September 2021. Andover, Mass.-based Transmedics said its system can now be used for ex vivo reanimation, functional monitoring, and beating-heart preservation of donation-after-circulatory-death hearts.

Boston Scientific Corp.’s image-guided programming software, Vercise Neural Navigator with Stimview XT, got the green light from the FDA for use with the company’s deep brain stimulation (DBS) portfolio in patients with essential tremor or Parkinson’s disease. The software, developed in a collaboration with Brainlab AG, provides more sophisticated image-guided programming tools for personalization of the stimulation therapy, halving the time needed for adjustments and increasing precision.

Axonics Inc. received FDA approval for its recharge-free sacral neuromodulation (SNM) implantable neurostimulator (INS) for bladder and bowel dysfunction. The F15’s primary cell requires no recharging or replacement for more than 15 years with normal use or 20 years at lower energy settings and the system is compatible with 1.5T and 3.0T full body magnetic resonance imaging scans.

The U.S. FDA’s device center has posted a report on premarket review performance metrics under the current device user fee schedule, and the latest data show an 83% rate of deficiency in first-cycle reviews of PMA original filings in the last three months of calendar year 2021. That rate is down somewhat from the 91% rate seen in 2016, but is up substantially from the 63% major deficiency rate seen in 2018, the low-water mark for this metric for more than a decade.

At long last, the FDA granted premarket approval to Senseonics Holdings Inc.’s fully implantable Eversense E3 continuous glucose monitoring (CGM), an implantable device that provides accurate glucose readings for six months. The CGM will be available in the U.S. through Senseonics’ commercial partner, Ascensia Diabetes Care Holdings AG, starting in the second quarter. In Europe, the previous generation Eversense XL is available today and the company plans to launch the E3 in the third quarter of 2022.

Medtronic plc received FDA premarket approval Friday for use of its Intellis rechargeable and Vanta recharge-free neurostimulators in patients with diabetic peripheral neuropathy (DPN), suddenly tripling the number of spinal cord stimulators approved for the indication. Medtronic’s implantable spinal cord stimulators (SCS) now join Nevro Corp.’s HFX, which has had the distinction since July 2021 of being the only device with FDA approval for DPN, also known as painful diabetic neuropathy (PDN).

In a move that will substantially expand the number of livers available for transplantation, the FDA granted premarket approval to Organox Ltd.’s Metra normothermic machine perfusion device for both donors after brain death (DBD) and donors after circulatory death (DCD). The approval allows preservation of organs by Metra for up to 12 hours.

Vagus nerve stimulation (VNS) researchers notched another success with FDA approval of a drug-free rehabilitation system that uses the technology to help patients who have lost mobility in their hands and arms as a result of ischemic stroke regain function. Microtransponder Inc.’s Vivistim pairs rehabilitation exercises with VNS to enhance their impact. The clinical study evaluated by the FDA for the system's approval showed that Vivistim doubled the improvement in upper extremity motor function compared to supervised rehabilitative exercises alone at six weeks and 90 days.

The FDA has approved Medtronic plc’s Evolut FX TAVR system for patients with symptomatic severe aortic stenosis. During Medtronic’s fiscal first quarter earnings call CEO Geoffrey Martha said the company will roll the latest generation system out in the U.S. market later this year, with a full launch planned in 2022.

Abbott Laboratories received FDA approval for its Amplatzer Amulet left atrial appendage occluder to treat people with atrial fibrillation who are at risk of ischemic stroke about a month earlier than generally expected, given the backlog at the FDA. The dual-closure device closes the left atrial appendage during the procedure, reducing the risk of blood clots immediately and eliminating the need for blood thinners both during the healing process and longer term.
