CYBERONICS INC LEAD MODEL 302 Back to Search Results
Model Number 302-20
Event Date 12/15/2005
Event Type  Injury  
Event Description

Initially, it was reported that during a vns system replacement surgery, it was observed that the patient's left vagus nerve was cut and that it presented with signs of having been cut for a long period of time. A neuroma was observed at the level of the cut which was at the lower end of the vagus nerve. No relationship of the cut to vns was noted at the time of initial report. It was later reported during a neurosurgeon expert meeting, that the diagnosis of a complete cut left nervus vagus with a neuroma was made during the replacement surgery. It was noted that the lesion was probably due to direct surgical trauma during the first implant procedure. It was noted that the patient had experienced partial improvement of epilepsy with vns therapy.
