The authors of a recent journal article see problems with the FDA’s approach to premarket review of artificial intelligence (AI) algorithms, including an undue reliance on single-site algorithm development. Regulatory attorney Brad Thompson told BioWorld, however, that hospital administrators want algorithms that maximize accuracy for their populations and are not averse to in-house development of just such an algorithm, thus creating a source of tension between what hospitals want and what the FDA expects.

The FDA has its hands full with the impact of the mutations to the SARS-CoV-2 virus, but test developers can count on an ever-increasing base of data for those viruses thanks to a new contract taken by the CDC. The CDC indicated recently that its sequencing efforts and that of other organizations churned out nearly 14,000 sequences for the week of April 3, but Aegis Sciences Corp., of Nashville, Tenn., announced April 7 that it had undertaken an agreement to perform next-generation sequencing of samples from all 50 states and Puerto Rico, ensuring plenty of access to up-to-date information on those mutations.
The management team at Respinova Ltd. is breathing easier with the FDA's 510(k) clearance of the company's Pulsehaler. Using pulsed air pressure, the device opens airways and clears secretions in patients with respiratory diseases.

The shortage of hearts for transplant is a matter of record for both cardiologists and patients, a problem that Transmedics Inc. proposed to solve with its Organ Care System (OCS). Despite several significant issues associated with the pivotal clinical study for the OCS, Transmedics snared a 12-5 vote that the benefits of the system outweigh the risks, an outcome that may bring at least some relief for heart transplant patients by mid-year if analyst expectations are on target.

Device reprocessing has intermittently prompted FDA action in an effort to tamp down on infection-driven adverse events for various types of endoscopes, and the latest spate of events involves endoscopes used in urological applications. While the three associated fatalities all took place outside the U.S., the FDA nonetheless indicated that it is considering the possibility that a device redesign is in order, a move the agency endorsed in connection with infections blamed on duodenoscopes.
Vysioneer Inc. has won the FDA’s nod for its Vbrain artificial intelligence (AI)-powered tumor autocontouring software. The company said Vbrain is the first AI device to receive FDA clearance for tumor autocontouring in radiation therapy. Vbrain is a neural network-based AI solution, trained from clinical data.
