Model Number 302-20
Device Problems Fracture; High impedance
Event Date 01/01/2008
Event Type  Malfunction  
Manufacturer Narrative

Device failure is suspected, but did not cause or contribute to a death or serious injury.

Event Description

It was initially reported that the vns pt had their lead and generator replaced due to an unk reason. Further follow up with the surgeon revealed that the pt had the lead replaced due to a lead fracture that was visualized on x-rays, and the generator was replaced at that time as well. Further follow up with the referring neurologist revealed that the pt was a new pt to the physician and when the device was initially interrogated and tested, high lead impedance resulted. The physician disabled the device at that time, and referred the pt for x-rays and to the surgeon to replace the device. The radiologists x-ray assessment indicated that there was "a disconnect of the electrodes in the neck". There was no report of manipulation of the device or trauma. The explanted lead and generator were discarded following surgery, and the devices are therefore not available to be returned to manufacturer for analysis.
