Additional information received from the hcp via the manufacturer representative (rep) reported that impedances of the lead were measured during revision on date notified which were found to be normal.There were no out of range measurements prior to surgery but were on the low normal range of 450-1300 ohms.The extension and ins were replaced at the request of the hcp, and following revision impedances were in the 900-2000 ohm range.It was stated that the physician assistant was concerned about the rate the ins had drained since the sep-(b)(4) as it had dropped to 2.96v, which is why the replacement was suggested.The issue was resolved at the time of additional information.See related regulatory report 3004209178-2016-22436.
