Event Date 01/01/2014
Event Type  Malfunction  
Event Description

It was reported that the patient had generator and lead replacement surgery on (b)(6) 2014. During the surgery, the surgeon saw fluid in the lead so completed a lead revision during the prophylactic generator replacement surgery. Attempts for product return have been unsuccessful to date. The products have not been received by the manufacturer. Previously, it was reported in (b)(6) 2013 that the patient was experiencing painful stimulation in the chest and neck areas. The painful stimulation resolved when the vns was disabled with the vns magnet. X-rays dated (b)(6) 2013 were later received and reviewed by the manufacturer. There was no evidence of lead twisting, or sharp angles suggestive of a lead break. It is noted the lead appears to be ¿stretched¿ across the chest, as if it may be pulled if the head was turned to the right. No obvious lead anomalies were seen. There was no known trauma or manipulation. The painful stimulation was reported to be positional and was thought to have resolved prior to referral for surgery, and the cause of the painful stimulation was unclear to the physician.

Manufacturer Narrative

Review of the lead device history records confirmed all quality tests were passed prior to distribution. Device failure is suspected, but did not cause or contribute to a death or serious injury.
