Model Number 104
Device Problems Connector pin failure; Device Issue
Event Date 04/12/2010
Event Type  Malfunction  
Event Description

During revision surgery to address high lead impedance (reported in mdr 1644487-2010-00238), it was noted by the surgeon that the header of the m104 implanted in the pt had become detached. The surgeon replaced the generator and obtained acceptable diagnostics results; therefore, the lead was not replaced. Good faith attempts to obtain the explanted generator for analysis have been unsuccessful to date. The device history record for the explanted generator was reviewed. No unresolved issues were found with any of the components used in the mfg of the generator that would have impacted device performance. Additionally, the hosp submitted voluntary mdr (b) (4) providing info regarding the revision surgery including the observation that the header was detached from the generator. The report also stated that the generator was believed to be the cause for the high lead impedance and since the high lead impedance resolved with generator replacement, the lead was not replaced.

Manufacturer Narrative

Device mfg records were reviewed. Review of mfg records confirmed no issues with the generator prior to shipment. Device failure is suspected, but did not cause or contribute to a death or serious injury.
