Model Number 304-20
Event Date 10/01/2015
Event Type  Malfunction  
Manufacturer Narrative

Event Description

It was reported that during a vns repositioning surgery for placement of a gastrostomy tube unrelated to vns, the surgeon pulled on the lead and it appeared to have broken while he tugged on it from its location at the upper incision. An implant card was also received indicating the lead was "fissured" during surgery when the lead was pulled back for repositioning. The generator was previously in the abdomen due to the patient's small size. The physician wanted to salvage the lead and replacement was not intended. They needed to re-tunnel for the lead so both incision sites were opened. The physician tugged the lead back, towards the neck. It was reported that the lead had frayed and broken near the lead pin and occurred while the physician was pulling on it very hard by hand. No surgical instruments were used on the lead. Diagnostics after the break were high. It was noted that the case was very difficult based on the patient铠size and complication due to the gastrostomy tube. It was reported that diagnostics were reportedly within normal limits prior to surgery. The generator was replaced as the battery was reported to be at near-end-of-service. The lead was discarded at the end of the procedure. The explanted generator has not been received to-date. No additional information has been received to-date.
