CYBERONICS, INC. LEAD MODEL 302 Back to Search Results
Model Number 302-20
Event Date 01/01/2010
Event Type  Injury  
Event Description

The patient reported on (b)(6) 2016 that her lead is protruding and is painful because she has lost a lot of weight. She stated she lost weight and device migrated and she has a knot where she thinks the wire connected to the generator. The patient needs a mri for her left breast but the generator is right above. Follow-up with the physician showed that she needs an explant asap and it's not clear if she needs it only for the mri or for the pain, protrusion and migration too. The physician states that the pain, protrusion and migration were present before her weight loss but now the device is more prominent in her neck since her 100 lb weight loss. The mass at her connector site of the lead and generator is believed to possibly be from the lead coming loss (probably from migration of the system). From the report it seems as though the lead is protruding, painful in the neck and possibly migrating causing a mass near the generator connection. Surgery has not occurred to date.

Event Description

Information was received from the physician on (b)(6) 2016. It was stated that the reason for the explant was due to the need for mri for breast lump, patient was a non-responder to vns therapy anyway, and patient was experiencing pain, protrusion and migration. It was stated that the patient experienced more pain after the weight loss. The issues began 6 to 7 years ago. No surgical intervention has not occurred to date.

Event Description

It was reported on (b)(6) 2016 that the patient had her device explanted that day. The explanted devices were disposed of.
