Event or Problem Description
It was reported that there were low impedances at the 2/3 combination, both in pre-op with the explanted implantable neurostimulator (ins) and intra-op with the new ins.The surgeon was unconcerned, since the low impedances presented in pre-op on an old (15 years old) system with no detrimental effects on therapy, were on an unused contact combination, and did not present on the individual contacts when tested in monopolar.
