CYBERONICS, INC. PULSE GEN MODEL 102 Back to Search Results
Model Number 102
Event Date 07/11/2012
Event Type  Malfunction  
Event Description

A company representative in (b)(4) was contacted by a vns treating physician and it was reported that a patient's vns pulse generator could not be interrogated. The generator could not be turned off, as it could not be interrogated, so the magnet was secured onto the area of the patient's chest where the generator was. It was also reported through the company representative that the patient was experiencing apnea. Further information was received from a neurologist stating that vns was related to the patient's apnea and that the apnea episodes occurred with the generator pulses. The product information was unknown to the neurologist because the generator could not be interrogated. It was planned to remove the generator on (b)(6) 2012. Troubleshooting was performed by testing the programming wand's 9v battery, but a fresh 9v battery was not tested; different wands and handheld computers were tested and the interrogation of the reported generator was not successful. The generator was interrogated in different locations; the handheld computer was not connected to an outlet during interrogation; other patients' generators could be interrogated with the physician's programming system therefore, ruling out an issue with their programming system. No causal or contributory programming or medication changes preceded the onset of the apnea; the patient has no medical history of apnea before implanting vns. Good faith attempts are underway to see if the explanted generator can be returned for analysis.
