Manufacturer Narrative

If information is provided in the future, a supplemental report will be issued.

Event Description

Information was received from the manufacturer¿s representative regarding a patient with an implantable neurostimulator (ins).It was reported that during a new implant procedure, high impedances (>4000 ohms) were seen.Impedances were run at 1 volts 210 sec and all bipoles were >4000 ohms.The physician wiped down the lead and reinserted.It was recommended to check the lead connection and to confirm the set screw was snug.The impedance was then re-run at 1.5 volts 210 sec and all bipoles except 2, 3 were >4000 ohms.When the impedance check was run at 2.0 volts 360 sec, the combination of c to 0 showed "???" but all bipoles were in range.There were no further complications reported or anticipated.
