CYBERONICS, INC. LEAD MODEL 302 Back to Search Results
Model Number 302-20
Event Date 05/09/2011
Event Type  Injury  
Event Description

It was initially reported by the epileptologist that the patient was to undergo a prophylactic generator replacement, and at the same time have his lead released from scar tissue. Additional information was received through an implant card indicating that the patient's lead was replaced and the patient had been experiencing coughing, tightness in the lead, and difficulty breathing. A review of the patient's history showed that the patient was implanted in 2006. The patient had started experiencing pain and tightness in his neck, following implant. This resulted in a procedure to release his lead wire from scar tissue in (b)(6) 2009. At that time, the procedure was performed for patient comfort. Follow up with the surgeon revealed that the patient's pain and tightness had reoccurred approximately a year after the previous surgery. The symptoms had gradually worsened, until it caused the patient pain and coughing when he turned his head to the right. During the procedure to loosen the lead wire from the scar tissue, the surgeon noticed damage to the "lead sheath" so he replace the lead wire. He indicated that the patient had developed severe fibrosis which entrapped the cable causing the pain, coughing, and discomfort. The fibrosis was also restricting the patient's neck motion. The surgeon stated that the procedure was performed primarily for patient comfort, but also potentially to preclude a serious injury. Follow up for additional information regarding the damage to the lead has been unsuccessful to date. The explanted products have not been returned to the manufacturer for product analysis.
