The U.S.FDA posted two warning letters to medical device manufacturers June 6, one each to Irhythm Technologies Inc., and Steiner Biotechnology LLC, and both warnings include citations for marketing for claims that are not in the FDA-reviewed product labels.
U.S. FDA inspections are not always a pleasant experience, particularly when the end result is a warning letter. One company, Sea-Long Medical Systems LLC of Waxahachie, Texas, says the experience was a positive experience in that the company’s new ownership gained an important appreciation for the necessary rigors of medical device manufacturing.
Dublin-based Medtronic plc, and the U.S. FDA have wrapped up their discussion of the December 2021 warning letter for the company’s manufacture of continuous glucose monitors, clearing a hurdle that was critical in restoring the company’s footprint in the U.S. market. Left unanswered from the resolution of the warning letter is whether the FDA believes that device makers need to track the number of devices in distribution vs. those in actual use in order to properly calculate the risk of device failure based on postmarket surveillance.
There are worse things for U.S. FDA-regulated companies than a warning letter from the agency, but both Abbott Point of Care Canada Ltd., and North American Diagnostics LLC were hit with a warning letter that included citations for failure to comply with the Quality System Regulation (QSR). North American may have believed it was no longer required to comply with the QSR as it ceased the manufacture of its COVID-19 rapid antigen test kits in July 2021, but the FDA advised the company that compliance is required so long as there is some chance that an adverse event arises in connection with the company’s product.
The U.S. FDA has issued a guidance on when to file a new 510(k) for a class II device that has undergone significant modification, but that doesn’t mean everyone in the device business is paying attention. The FDA hit Synovo Production Inc., of Fullerton, Calif., for a number of violations of the Quality System Regulation (QSR), but also alleged that the manufacturer/specification developer made a number of modifications to its femoral resurfacing cup for hip implants without a new regulatory filing, leading the agency to direct the company to immediately cease production of the device.
The U.S. FDA’s surveillance of duodenoscopes and other endoscopes was initially driven by concerns about device sterility, but recent inspections of manufacturing sites operated by Olympus Medical Systems Corp., in Japan have fed warning letters for lapses from various regulations. In the latest warning letter, the agency cited one of the company’s sites in Tokyo for both quality system and medical device reporting lapses, the second warning letter issued to the company in roughly three months.
It may still be true that a majority of medical devices are manufactured in the U.S., but that doesn’t stop the FDA from dropping a warning letter on facilities located outside the U.S. (OUS). In one of these warning letters, Microvention Inc., of Aliso Viejo, Calif., received a warning letter for its plant in Costa Rica, although the FDA waited until the second week of February to post the Sept. 30, 2022, warning.
The U.S. FDA inked a Dec. 20, 2022, warning letter to Righteye LLC that handed the company a list of quality system issues in dire need of redress, but the agency was more concerned about off-label promotion of the Righteye vision system as a method for evaluating the patient’s ocular tremors as a sign of Parkinson’s disease.
The U.S. FDA’s surveillance of endoscopes related to reprocessing issues has yielded two more warning letters, one each for Tokyo-based Olympus Medical and its Aizu Olympus subsidiary, both of which were cited for inadequate procedures for medical device reports (MDRs).
U.S. FDA warning letters for medical devices are relatively rare these days, and the Oct. 6, 2022, warning to Empowered Diagnostics LLC of Pompano Beach, Fla., suggests that COVID tests are still front and center where FDA enforcement is concerned.
