Manufacturer Narrative

Review of the available programming and diagnostic history. Device failure is suspected, but did not cause or contribute to a death or serious injury.

Event Description

Additional information was received that the high impedance was first observed on (b)(6) 2015 and was not observed prior to that. Patient was referred for lead revision and prophylactic generator replacement but no surgical interventions have occurred to date.

Event Description

Additional information was received that the patient underwent surgery on (b)(6) 2015. It was reported that the patient's implanted generator and lead were not removed as the surgeon did not want to create a new scar. Instead, the surgeon implanted a new vns generator and lead on the right side of the patient. The lead was implanted on the right vagal nerve. The patient and family agreed with the surgeon and therefore the old devices were not touched. The surgeon was informed of the cardiac risks of implanting vns system on the right side. The neurologist was also made aware of the two systems implanted in patient and that the system on the left will show high impedance as this was not corrected. Neither the patient nor the surgeon at this time feels that it is necessary to remove the suspect device.
