Event Type  Injury  
Manufacturer Narrative

Device mfg records were reviewed. Review of mfg records confirmed sterilization for both the generator and lead prior to distribution.

Event Description

It was reported that the pt had surgery to remove the vns device due to infection and cellulitis. Pt went to er on (b)(6)2010 as her caregivers found the generator site had opened up (generator was visible) and was draining. Physician prescribed antibiotics. The device was removed (b)(6)2010 and the infection site was debrided and cleaned. The surgeon thought perhaps the pt's body had rejected the implant which caused the infection. However, per neurologist, the generator became loose and migrated slowly over 5 years to the pt's armpit, and came out. Once it was exposed to air, the infection started. It was also noted that the pt was likely manipulating the device which may have contributed to the events. Pt will be reimplanted in the future in a different location to prevent pt manipulation of the device. Explanted product was returned to the mfr and underwent analysis. Upon analysis, no anomalies were noted. Review of mfg records confirmed sterilization for both the generator and lead prior to distribution.
