Glaukos Corp. received a green light from the FDA for its Iprime device for the delivery of viscoelastic fluid during ophthalmic surgery, which could help the company to recover some of the revenue lost by cuts to reimbursement for its minimally invasive glaucoma surgery (MIGS) product, Istent. A launch date has not been announced.

Jelikalite Corp. has received a breakthrough device designation from the FDA for its wearable neurostimulation device Cognilum. The home-based system aims to reduce symptoms of moderate to severe autism spectrum disorder in pediatric patients aged 2 to 6 years. The designation was based on the results of a double-blind, placebo controlled clinical trial of 30 pediatric patients with moderate to severe autism, which showed the technology can significantly improve symptoms.

Bioventus Inc. has received FDA 510(k) clearance for a device that enables surgeons to remove bone in hard-to-work spaces during minimally invasive surgery. It acquired the company that developed the tool, Great Neck, N.Y.-based Misonix Inc., in October.

FDA recalls are fairly commonplace events and infrequently require any field corrections of inventory on the market, but Puritan-Bennett Corp. has asked customers to quarantine 135 of the company’s 980 series ventilators due to assembly problems that could cause the devices to cease operating.

Glaciers are known to move slowly, but so is government, and the FDA needed seven years to make effective an order that cerebrospinal fluid shunts be deemed class II devices. The classification was applicable as of Aug. 22, 2014, in connection with a de novo petition filed by no less than industry colossus Medtronic plc, of Dublin, in a process that began in 2012, possibly earlier.

The run on at-home COVID-19 tests may be for naught. The FDA warned that the popular rapid antigen tests recommended to keep New Year’s Eve revelers, relatives visiting elderly grandparents and workers exposed to the coronavirus from spreading COVID-19 are less likely to detect the Omicron variant than earlier strains of the virus. “Early data suggest that antigen tests do detect the Omicron variant but may have reduced sensitivity,” the agency said in an update on Dec. 29. Despite the higher rate of false negatives, the FDA said individuals should continue to use the tests. Those experiencing symptoms or with a high likelihood of infection based on exposure should follow-up with a molecular test if their antigen test returns a negative result.

The Verifying Accurate Leading-edge IVCT Development (VALID) Act seems poised for passage in 2022, a bit of welcome relief for those stuck in the regulatory twilight world of the lab-developed test (LDT). However, Carly McWilliams, director of regulatory policy for North America for Roche Inc., said recently at the recent Food and Drug Law Institute enforcement meeting that the VALID Act is likely to leave the question of a user fee schedule for a future Congress, given that the associated rulemaking, guidance development and compliance activities are likely to consume the better part of, if not the entirety of, the next five years.

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.

Some U.S. FDA warning letters are mostly about documentation, but the key consideration in the widely publicized Dec. 9 FDA warning letter to Dublin-based Medtronic plc seems to be whether Medtronic had a proper understanding of the risk created by malfunctioning infusion pump retainer rings. That difference of opinion regarding risk took a significant bite out of the company’s shares and boosted the fortunes of its rivals in the diabetes space, a cautionary tale regarding the hazards associated with a failure to understand how the FDA sees the risk of device malfunction. The FDA had reported in October 2021 a pair of recalls of Medtronic’s Minimed insulin pumps, although one of the issues cited was related to cybersecurity concerns. The two recalls affected nearly half a million units combined, and could have significantly affect access for some patients.

The FDA has delivered on a final guidance for non-clinical and clinical investigations of devices used for treatment of benign prostatic hyperplasia (BPH), needing only a year and a half to convert the draft guidance into a final version. The final guidance retains the draft’s recommendation that pivotal studies follow patients for at least a year, a provision some in the med-tech industry saw as unnecessary in some instances. The scope of the July 2020 draft included non-clinical testing, a novelty compared to previous guidance on the topic. The scope of this latest guidance includes four product codes, including KNS for endoscopic electrosurgical instruments, and the FDA included several specific suggestions for the use of thermotherapy and permanent prostatic stents as treatments for BPH.
