CYBERONICS, INC. PULSE GEN MODEL 102 Back to Search Results
Model Number 102
Event Date 04/25/2011
Event Type  Injury  
Event Description

It was reported that a patient had an episode of intermittent esophageal pain that lasted several hours. The generator's normal mode output was disabled, although the magnet output was left programmed. The patient did complain of pain when using the magnet. Diagnostic testing on (b)(6) 2009 showed the device to be properly functioning. Furthermore, the patient's generator was reported to be able to move around in her chest. Follow-up from the patient's physician at the time revealed that the site would not provide any more information on the subjects. However, at a later date it was indicated that the patient had her generator removed due to "pain" in her axilla region, though a migration event could not be confirmed. Additional information from the patient's surgeon's office stated the patient "complained of pain in the axilla and numbness in the left arm from the generator when lying on her left side". Clinic notes from the neurologist indicated that he did not believe the vns was causing left arm numbness. Analysis on the returned generator showed that the septum was not returned, but no evidence of body fluids were observed in the header septum cavity, thus eliminating the possibility of a potential unintended electrical current path through body fluids. There were no performance or any other type of adverse conditions found with the pulse generator. Attempts for further information have been unsuccessful to date.
