Model Number 302-20
Event Date 06/30/2009
Event Type  Malfunction  
Event Description

Neurology reported their pt was complaining of pain in the left neck area that seemed to be an electrical type of buzz. The pt reported that it was a near daily occurrence lasting a brief number of seconds. If the pt pushed up on the soft tissue under her left mandible she could decrease the symptoms. The pt was also having an aura- like symptoms around the same time as her pain events. Diagnostics were performed and confirmed proper device function (systems: ok/ok/2/no; normal mode: ok/ok/3/no). It was planned to send the pt for revision since they had been implanted approx 6 years and for pt comfort related to their pain events. The pt's surgeon was concerned there was "some type of malfunction. " neurology confirmed device function and device to be "in working order. " the pt had full revision surgery and the explanted products are at the mfr pending completion of product analysis. The return product form documented the pt had a lead break. X-rays were reviewed prior to surgery that showed no device anomalies in the images available, though the presence of the pt's previous lead and surgical staples was identified. The x-rays confirm the presence of an adequate strain relief bend and the absence of a strain relief loop. Two tie-downs appeared to have been utilized, though both were used to secure the strain relief bend in place.
