CYBERONICS, INC. LEAD MODEL 302 Back to Search Results
Model Number 302-20
Event Date 01/21/2015
Event Type  Malfunction  
Event Description

It was reported that during generator replacement surgery, device diagnostics resulted in high impedance (dcdc=7). It was reported that device diagnostics were unable to be performed prior to generator replacement due to the previous generator being at end of service. A pin reinsertion was performed which did not resolve the high impedance. The surgeon left the lead implanted. Lead revision surgery will be planned at a later date. No known surgical interventions have been performed to date.

Manufacturer Narrative

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

Event Description

It was reported in clinic notes that the patient had lead revision surgery. No further relevant information has been received to date.

Manufacturer Narrative

Explant date, corrected data: follow-up report #1 inadvertently listed the incorrect explant date of the suspect device.

Event Description

The explanted lead was discarded. Therefore, no analysis could be performed.

Event Description

Clarification was received through operative notes that the patient's lead was not explanted in (b)(6) 2015. Exploratory surgery was performed, and the high impedance resolved after the lead pin was reinserted into the generator. The high impedance then was present again in (b)(6) 2017. Therefore, the high impedance resolved only temporarily. The report of high impedance after (b)(6) 2017 was initially reported in mfr. Report #1644487-2017-03204 as it was believed to be on a different lead. The patient had full revision surgery, but the products were discarded by the explanting facility. No further relevant information has been received to date.
