Model Number 302-20
Event Date 04/05/2012
Event Type  Malfunction  
Event Description

It was reported that the patient's vns was now indicating high impedance with dcdc=7 during a system diagnostic test. The patient has not had any adverse events however the physician indicated that she believes the generator has been migrating towards the patient's armpit. The physician indicated that this migration could have contributed to the high impedance. X-rays were taken that reportedly did not indicate any issues however they will not be sent to the manufacturer for review. No trauma or manipulation is believed to have occurred. Last known diagnostics were taken on (b)(6) 2010. Attempts for additional information have been unsuccessful to date.

Event Description

Surgery to replace the patient's lead and generator has occurred. Diagnostic results following lead and generator replacement were normal following replacement. It was noted that a non-absorbable suture had been previously used to secure the generator. Attempts for the return of the explanted lead and generator were unsuccessful as the implant hospital indicated they believe the explants had been discarded after surgery.
