Event Description

The manufacturer representative (rep) reports patient was scheduled for stage 2 implant of the extension and implantable neurostimulator (ins).Caller reports the left lead was having impedance issue on the directional contacts 1 and 2, showing >5k ohms.Caller reports they perform the usual impedance troubleshooting, but did not resolve.When the physician attempted to load the lead into the extension port, it felt tight trying to get the lead in, the lead was not able to advance all the way in, the setscrew was not tight.The physician noted the end of the lead, was not ridge enough to apple pressure to advance the lead, caller reports the lead became kinked on the contacts.All the contacts were showing >5k ohms.Caller reports the kinked made it worse when physician tried to check the connection.No symptoms reported.

Event Description

Additional information received from the manufacturer¿s representative (rep), which was confirmed with the healthcare provider, reported they were completing a bilateral stage 2 procedure when the hcp noted the connection site felt ¿tight¿ at the lead to extension connection.When they went to teste impedances, they were >5,000 ohms on 2 of 3 directional contacts on both contacts 1 and 2.It was the same 2 on both: 1b, 1c, 2b, 2c.Troubleshooting was performed, and they noticed there seemed to be some space between the grey collar-marker on the lead and the extension.The hcp said it felt tight and they checked that the set screw on the extension was not too far advanced, it was not.They disconnected and wiped the lead wet/dry and reconnected to the extension.They also tried flipping the extensions in the ins ports to be sure it wasn¿t the battery.There were no visible breaks or areas of concern.The hcp then requested trying a new extension which resulted in worse impedance across all contacts on the lead.The rep suggested testing the lead with a lead test cable, and they observed it was in fact the lead.The hcp noted there seemed to be a ¿kink¿ just past the contacts on the lead where the lead was bent from the pressure of being inserted into the extension.At this point the entire lead was now showing >10,000 ohms for all contact impedances.The hcp stated this must have been caused by the resistance he faced when inserting the lead into the extension and their continued efforts to correct the impedances which included several disconnections and reconnections which ultimately made the situation worse.A revision surgery was going to take place, but not yet scheduled.
