LIVANOVA USA, INC. LEAD MODEL 303 Back to Search Results
Model Number 303-20
Device Problems Corroded ; Fracture; Device Contamination with Body Fluid
Event Date 05/06/2018
Event Type  Malfunction  
Event Description

High lead impedance was observed on a patient's vns system during a follow-up visit. The physician elected to perform surgery to replace the patient's generator, as the battery was low, and planned to replace the lead upon evaluating its status at surgery. X-ray images were taken of the system prior to surgery, but the physician did not observe any lead discontinuities in the images. Upon explanting the generator during surgery, the physician observed that the lead was tangled and decided to replace the lead also. The physician observed a fracture in the lead after it was explanted. The physician reviewed the x-ray images again and observed that the fracture was actually visible in the images. The physician was unsure whether patient manipulation contributed to the lead fracture. X-ray images from several clinic visits were received by the manufacturer, but have not been reviewed to date. The explanted lead and generator have not been received by the manufacturer to date. No additional relevant information has been received to date.
