LIVANOVA USA, INC. LEAD MODEL 304 Back to Search Results
Model Number 304-20
Device Problem High impedance
Event Date 03/17/2019
Event Type  Malfunction  
Event Description

Patient presented with high lead impedance and the device was disabled. It was noted that the physician reviewed x-rays and was unable to determine whether or not a clear wire break was present. It was noted that the patient reported no longer feeling stimulation resulting in the impedance being checked and found to be high. X-rays were received and reviewed for the patient. The connector pin can be seen coming through the second connector. The filter feedthru were confirmed to be intact. The lead wires appeared intact at the connector pins. No gross discontinuities were identified in the visible portion of the lead. A sharp angle was noted at the top of what appears to be the strain relief loop. It should be noted that the sharp angle may be a result of the angle of the image. The cause of the patient¿s high impedance could not be determined based on the images provided. Note that the presence of a micro-fracture and/or a lead discontinuity could not be ruled out in the portion of the lead that is not visible in the provided images. Further information was received that the patient reported no trauma or manipulation to the area. It was noted that suddenly the stimulation was no longer perceived. No further physician¿s assessment of the high impedance was provided. No known surgical intervention has occurred to date. No other relevant information has been received to date.
