MAUDE Adverse Event Report: MEDTRONIC PUERTO RICO OPERATIONS CO. PERCEPT; STIMULATOR, ELECTRICAL, IMPLANTED, FOR PARKINSONIAN TREMOR

Model Number B35200

Device Problem Low impedance (2285)

Patient Problem No Clinical Signs, Symptoms or Conditions (4582)

Event Type  malfunction  

Event Description

It was reported that there was low impedance (188 ohms) on right electrode 11.The battery was going to be switched to a rechargeable implantable neurostimulator (ins).It was confirmed that they could obtain optimal stimulation with the new settings and impedance was ran.The impedances were as followed: 0=1191 1=1304 2=967 3=1124 8=1191 9=1018 10=940 11=2022. for what concerns the electrode 11, the electrode is showing slightly high impedance value compared to the normal (2022 vs 2000 for monopolar).It was recommended to keep this electrode under control and monitor for change.

Event Description

Additional information was received: it was reported that the ins was depleted due to normal battery depletion, although they weren't sure how much the high parameters and impedances may have affected it.The cause of the high impedances was not determined.When they switched from a percept to a rechargeable device the impedances did change a bit.When they changed to the new ins the impedances were slightly better but still there.
