- Software design
- Action
- Cyberonics notified consignees of recall via letter on 02/07/08. Consignees were notified of reset issue in which during a strong magnetic field, the software may report an error even though no error occurred. This error causes the generator to reset, which disables the generator (i.e., no stimulation delivered). Physicians should inform any potential and currently implanted patients of the possibility of this event. Patients should continue with their regularly scheduled visits as determined by their physician. If this event is suspected, physicians should interrogate the device as described in the Physicians Manual to confirm the generator has been reset and Cyberonics should be contacted for any additional instruction.
