Hypertrophic cardiomyopathy (HCM) might not be the talk of the town in the world of cardiology medical devices, but the condition has a devastating effect on a large number of lives, particularly in the case of early disease onset. San Francisco-based Viz.ai Inc. has won a de novo from the U.S. FDA for its algorithm for identification of patients at risk of HCM, the aptly named Viz HCM, a product the company believes will not only save lives but may save the U.S. health care system a large amount of money as well.

The U.S. Centers for Medicare & Medicaid Services has proposed to terminate the coverage with evidence development requirement for the use of positron-emission tomography (PET) imaging for patients suspected of suffering from beta amyloids, a marker of Alzheimer’s disease (AD). However, CMS is also considering a removal of the coverage policy that limits each patient to a single PET scan per lifetime, although the proposal to allow Medicare administrative contractors (MACs) to determine coverage is drawing fire from industry and physician groups alike.

The Biden administration recently announced an extension of the comment period for a request for information on harmonization of cybersecurity regulation, a proposal that could conflict with FDA regulation of medical device cybersecurity.

Boston Scientific Corp. has managed its Polarx device to another regulatory approval, this time a nod from the U.S. FDA, giving the company access to one of the world's premier markets. The news comes four months after the company obtained a CE mark for the device, opening the door to two jumbo markets in a move the company hopes will ensure the device will provide solid returns on its investment.

A timely discharge from the hospital requires that a lot of things go just right, and GE Healthcare just scored a win from FDA for its Portrait vital signs monitoring system that offers wireless, wearable tracking of oxygenation, pulse and respiration rate. GE said this system allows patients to be mobile during those first few critical hours post-surgery while providing non-stop vital sign tracking, a development that may allow clinicians to intervene more quickly when problems arise and thus help the patient recover and head home without setbacks.

Transcatheter aortic valve replacement (TAVR) devices are all the rage for treatment of aortic valve disease, but that doesn’t mean valve reconstruction via the so-called Ozaki procedure has been consigned to the pages of medical history. The U.K.’s National Institute for Health and Care Excellence has recommended that trusts in the U.K. health system use this procedure only in clinical trials at least for the time being, although the agency noted that the Ozaki procedure allows the patient to sidestep the need for long-term antithrombotic therapy, a big selling point for patients and clinicians alike.

Developers of medical technology have many concerns about the U.S. Centers for Medicare & Medicaid Services’ (CMS) handling of coverage and reimbursement, but those controversies have typically revolved around process. A new report sponsored by industry steers a somewhat different tack, however, arguing that while there are issues of process, one key issue is that of funding, a problem that only Congress can remedy.

The inter partes review (IPR) process used to adjudicate patent disputes in the U.S. has had its share of critics, but ongoing patent litigation revolving around nerve stimulation technology between Axonics Inc., and Medtronic plc has disclosed another bone of contention in how IPRs are handled. The Court of Appeals for the Federal Circuit has ruled that a patent holder, Dublin-based Medtronic in this instance, can offer a new claim construction for its disputed patent once an IPR has been instituted, but said also that the Patent Trial and Appeal Board (PTAB) had erred in not allowing Axonics to respond to the new claim construction, sending the related IPRs back to the PTAB for another look.
