It was reported that during an elective ipg replacement procedure, intra operative impedance check revealed high impedance on 4 different contacts of one of the leads.The patient was returned to or and surgical intervention was undertaken wherein the lead was removed from the ipg, wiped and reinserted to address the issue.Impedance checked reëlected that the high impedance resolved on 3 of the contacts, leaving only high impedance on contact 1.Effective therapy was established post op.Investigation was unable to determine which of the leads had high impedance.
