IT WAS REPORTED TO MFR THAT THE VNS PT WAS HAVING SURGERY DUE TO HIGH LEAD IMPEDANCE. X-RAYS WERE TAKEN AND REVIEWED PRIOR TO SURGERY AND ACCORDING TO THE SURGEON THEY WERE INCONCLUSIVE. DURING SURGERY, THE SURGEON NOTED A LEAD BREAK "AT THE CONNECTOR BOOT AREA." THE SURGEON REMOVED ALL BUT APPROX 2 CM OF THE LEAD. ADDITIONALLY, THE SURGEON WAS NOT ABLE TO IMPLANT A NEW LEAD ON THE LEFT VAGUS NERVE AS THERE WAS "NOT ENOUGH ROOM ON THE NERVE" DUE TO SCAR TISSUE FORMED. A NEW GENERATOR WAS IMPLANTED BUT THE LEAD WAS NOT REPLACED. ATTEMPTS TO OBTAIN ADD'L INFO AND THE EXPLANTED DEVICES FOR ANALYSIS ARE UNDERWAY.
