Acutus Medical Inc. scored big with regulators in recent weeks. The company, which focuses on devices to diagnose and treat cardiac arrhythmias, received FDA approval to launch an investigational device exemption clinical trial for its Acqblate Force sensing ablation catheter and system in atrial fibrillation just two weeks after gaining CE mark approval for a broad suite of electrophysiology products.

The FDA granted breakthrough device designation to Volumetrix LLC for its NIVAHF monitoring system for heart failure. The device is the first application of the company’s noninvasive venous waveform analysis (NIVA) technology, which captures and analyzes vital information about blood volume to assess patient status.

The controversy over the use of paclitaxel in devices for the peripheral vasculature has taken a significant bite out of sales, but a new study serves to help reverse the narrative regarding mortality. According to a study of more than 168,000 Medicare patients, stents and angioplasty balloons coated with paclitaxel (PTX) were non-inferior to non-coated devices for mortality out to nearly three years, a finding that may encourage clinicians to return to normal utilization patterns and thus help to restore sales volumes.

The FDA’s multiyear effort to rewrite the Quality System Regulation (QSR) to align with ISO 13485 could significantly ease the regulatory burden for device makers in multiple markets, but that effort has floundered over the past couple of years. The associated rulemaking is back on the FDA’s agenda, signaling that device makers might soon be able to deploy a single and relatively inexpensive quality management system, which in principle would significantly reduce their compliance costs.

The FDA issued a June 10 warning letter to Innova Medical Group Inc. in connection with the company’s rapid antigen tests for the SARS-CoV-2 virus, an action that accompanies a class I recall and a safety communication.

The FDA has authorized two batches of Johnson & Johnson’s COVID-19 vaccine from a troubled Emergent Biosolutions Inc. manufacturing facility to be made available under emergency use authorization (EUA) while determining that several other batches were unsuitable for use. While the FDA would not confirm the number of unsuitable batches, the newly authorized batches, however, can be used in the U.S. or exported.

The FDA granted Neurescue a "two-fer" on its intelligent balloon catheter for aortic occlusion with 510(k) clearance for emergency control of hemorrhage and investigational device exemption for use in cardiac arrest. By inflating a soft balloon at diaphragm level, the device dramatically increases perfusion to the heart, brain and lungs within a minute of deployment via the femoral artery.

Of all the controversies surrounding the FDA, the agency’s reliance on user fees and its use of accelerated review of therapies might be the most consistent sources of public angst. Coleen Klasmeier, a partner of Sidley Austin LLP, told BioWorld that while she is not particularly concerned about regulatory capture stemming from FDA reliance on user fees, it may be appropriate to ask whether the drug premarket review process leaves FDA staff with more confidence in a new drug application than the data would seem to suggest.

Medtronic plc snagged FDA premarket approval for its recharge-free implantable neurostimulator (INS), Vanta, for patients with intractable pain. The spinal cord stimulator offers up to 11 years of device life, with optimal programming. That represents a 10% improvement on the Dublin-based company’s previous longest-lasting INS, Primeadvanced, and a near doubling of device life compared to Abbott Laboratories’ Proclaim and Boston Scientific Corp.’s Wavewriter Alpha, using the settings recommended in the clinician manuals.
