CYBERONICS, INC. LEAD MODEL 302 Back to Search Results
Model Number 302-20
Event Date 03/06/2012
Event Type  Malfunction  
Event Description

Additional information was received as clinic notes including the most recent note dated (b)(6) 2012, that indicated that the patient has not had any seizures. The note on this date also details the high impedance being found and the patient indicating that she does not feel the device working likely as a result of the high impedance. A note dated (b)(6) 2012, indicates the physician checked the device on (b)(6) 2012 and it was noted that it "seems to be working well. " the vns was later checked and adjusted on (b)(6) 2012, however, no diagnostics or observations on the device performance were noted. The notes indicate the patient had an mri of her shoulder on (b)(6) 2012, which manufacturer labeling does not recommend.

Event Description

Additional information was received as an implant card indicating the lead and generator had been replaced. The explanted products will not be returned per hospital policy. Follow-up with the site found that it is believed that the previous system was explanted and the patient only has one vns system in place contrary to the previous indication by the site.

Event Description

It was reported that the patient's vns was now indicating high impedance on system and normal mode diagnostic tests. Source code from the generator from the last available date to the manufacturer on (b)(6) 2011, shows normal device function. Attempts for additional information have been unsuccessful to date. No adverse events have been reported. Surgery to replace the patient's lead and generator is likely.

Manufacturer Narrative

Analysis of programming history. Device failure is suspected, but did not cause or contribute to a death or serious injury.

Event Description

Additional information was received as an implant card indicating that surgery to replace the patient's vns generator occurred on (b)(6) 2012. The lead was not replaced at that time. Additional information was later received indicating that the surgeon plans to implant a second lead on the right side instead of replacing the previous lead. The previous lead implanted on the left side likely has a fracture since the high impedance did not resolve following generator replacement. The generator implanted for the replacement on (b)(6) 2012 will be placed on the new lead. Surgery for lead revision and generator repositioning is likely.

Manufacturer Narrative

Initial report inadvertently did not indicate 30-day.
