A manufacturing representative (rep) reported they were doing a brand new implant with a lead.There were no extensions and when they hooked up the lead implantable neurostimulator (ins) they had high impedance.They removed the lead an wiped it off and reconnected and tested at a higher voltage, but the obtained similar results.Then they tested in the mltc and both sides were fine.They opened a new ins and got similar high impedance.With the 1st ins, 4,5 were fine, but everything else on 0-7 were high.They noted 8-15 were normal and now 3 was fine, but everything else 0-7 was out.During troubleshooting the rep swapped lead tails into opposite ports on the 2nd ins and ran impedance at 3v.They indicated the lead that had been having issues was okay in the 8-15 port, and only contact 3 was over 40,000ohms.The rep then swapped lead tails into opposite ports on the 1st ins and again, the issue seemed to follow the lead as 0-7 port was fine and contact 15 on 8-15 was out.They tried the mltc again and everything tested fine.There was not visible damage to the leads.The rep indicated they would be implanting the 2nd ins.The issue occurred intra-operation and there were no symptoms reported.Follow up information from the rep stated the lead was positioned with the tip in the right gutter and the proximal end of the lead midline and they thought it anatomical.They stated that the system was working fine and the patient was getting good coverage.All impedances were 1500-1600 as of the report on (b)(6) 2016.The ins was indicated for spinal pain.
