CYBERONICS, INC. PULSE GEN MODEL 102 Back to Search Results
Model Number 102
Event Date 02/25/2012
Event Type  Malfunction  
Event Description

It was reported that during a clinic appointment, the patient and nurse were swiping the patient's vns magnet. However upon interrogation of the generator, no magnet swipes were registered. Follow up with the physician revealed that he has "no dates of this activation" and did not have additional information. A request to the physician's office was made requesting the patient's programming/diagnostic/magnet history. However, the history has not been received to date. The patient was seen at the clinic again on (b)(6) 2012 and the magnet mode reportedly did not pick up the vns stimulation again after trying two additional times. The site feels that the patient needs a new magnet. However, there is evidence that the patient was receiving stimulation with the magnet because the patient felt dizzy when she swiped the magnet, but when the nurse swiped the magnet, the patient did not feel dizzy. The physician's office thought the dizziness was likely related to a sinus infection. A review of the magnet history in the in-house database showed regularly occurring magnet activations. The last available history was on (b)(6) 2010, with 4706 magnet activations.

Event Description

The patient had prophylactic generator replacement surgery on (b)(6) 2012. Attempts for product return have been unsuccessful to date.

Event Description

The explanted generator was received by the manufacturer on 07/05/2012. However, product analysis has not been completed to date. The return product form did not provide the reason for replacement.

Event Description

Product analysis for the explanted generator was completed. In the lab, the device output signal was monitored for more than 24-hours, while the generator was placed in a simulated body temperature environment. Results showed no signs of variation in the pulse generator's output signal and demonstrated that the device provided the expected level of output current for the entire monitoring period. Magnet functions performed during the output-monitoring test (at a distance of one-inch, spacer block, from generator), demonstrate the appropriate magnet operations for the pulse generator at the programmed settings. The pulse generator diagnostics were as expected for the programmed parameters. In addition, a comprehensive automated electrical evaluation showed that the pulse generator performed according to functional specifications. There were no performance or any other type of adverse conditions found with the pulse generator.
