Event Description

It was reported that the impedances are out of range.The unipolar impedances are all >5000ohms and the bipolar impedances are between 995 - 3536 ohms.Technical services (ts) reviewed that it is most likely that the extension came out of the ins socket.The provider replaced the implanted device and the impedances remained the same.During investigation, additional information received from the manufacturer¿s representative (rep) reported they reviewed previous impedances and dating back to 2020 impedances had been out of range.The patient mentioned they felt things may have been ¿off¿ since the beginning.The rep mentioned the patient was symptomatic (rigid and stiff) so it was unknown if they had been getting therapy or not.Images and impedance testing was reviewed which appeared the lead became disconnected from the extension therefore it was likely fluid/tissue had ingressed into the distal end of the extension causing the expected impedance measurements so that the monopolar path gave a reading as opposed to just over 40,000 ohms (but this wasn¿t confirmed).It was reviewed that while the bipolar measurements are ¿in range¿ they were still suspect given the imaging and what was occurring with monopolar pairs.It was unknown what was going to happen next as they were waiting for neurologist/neurosurgeon for further steps.

Event Description

Additional information was received from a manufacturer representative (rep) reporting that the event has not been resolved.They are scheduling extension replacement for january.
