Model Number 302-20
Event Date 08/08/2014
Event Type  Malfunction  
Event Description

It was reported that the vns patient was having issues with pain and with device migration. Clinic notes were received indicating that the patient had severe fatigue and tremors over the last two months. She later reported having a strange tremor in her head that occurred several times per day. It was noted that patient¿s device had migrated from its original position and was located at the wall of the axilla. Chest and neck x-rays were ordered because the patient reported occasional shocking sensations to the left side of the neck. The patient was instructed to temporarily disable her device with the magnet to determine whether her symptoms would subside. An implant card was received indicating that the patient underwent generator and lead replacement surgery due painful stimulation, shocking sensations and lead discontinuity. The patient¿s lead reportedly fell off the patient¿s vagus nerve and caused high impedance. The explanted generator and lead have not been returned to date. Attempts for additional relevant information have been unsuccessful to date.
