FDA (Devices) recall action 95435
The FDA (Devices) publishes a recall like this one as 2 separate product records. They share a firm, a date and a cause; this page is all of them in one place, so the scale of the action is visible rather than spread across 2 pages.
Vagus nerve stimulator generators may stop delivering stimulation due to an internal, mechanically activated component that may become stuck in a closed position, which may result in patients returning to baseline seizure frequency or depressive symptoms and in the longer term, patients may be required to undergo generator replacement surgery to replace their device.
The agency’s own wording, quoted from the enforcement report.
The unit total adds up the quantities the agency stated for each product. Where a product record gave no figure, or gave a weight rather than a count, it contributes nothing — so the real total is at least this, never less.
The SenTiva and SenTiva Duo vagus nerve stimulation generators may stop delivering therapy due to an internal mechanical component becoming stuck, causing potential loss of seizure and depression control.
LivaNova's SenTiva VNS generators (48 units) may stop delivering stimulation due to a mechanical defect. Patients may experience return to baseline seizure or depressive symptoms and may require replacement surgery.
