CYBERONICS, INC. LEAD MODEL 302 Back to Search Results
Model Number 302-20
Event Date 04/28/2010
Event Type  Malfunction  
Event Description

Our country manager for (b)(6) reported that there was a patient with high lead impedance on their system diagnostic testing. Over the last month it was reported that the patient experienced an increase in seizures at their pre vns baseline rate, new seizure type and tonic seizures with falls to the ground. Additionally it was reported that the patient had a violent fall in (b)(6) with trauma on the face. The patient had falls prior to vns implantation with their seizures and now, they have returned. The patient's seizures are being attributed to their high lead impedance/lead break. The patient's mother cannot remember tonic seizures with so violent falls before implantation. Reported it seems that these may be a new type of seizures. X-rays were reviewed at manufacturer and showed a gross lead discontinuity in the anchor tether area of the lead that is in the neck area. Lead replacement is scheduled for (b)(6) 2010. Good faith attempts will be made for the explanted product to be returned for product analysis.

Manufacturer Narrative
