One guideliner catheter, was returned for evaluation.The manufacturing record review was completed and no related nonconformance's were found.There are no related nonconformance associated with this lot therefore supporting the device met material, assembly and performance specifications.The shaft successfully passed through a ring gage confirming it was within specification.The guideliner was visually examined and found to be severely damaged.The half-pipe channel / collar transition was damaged and twisted.The half-pipe channel was twisted, and the pushrod was beginning to pull away from the device.This damage is consistent with extending the guideliner more than 10cm outside the guide catheter (guide sheath).It is likely that upon withdrawing the guideliner back into the guide catheter (guide sheath), the collar of the guideliner became stuck on the distal section of the guide catheter (guide sheath).Further removal of the guideliner would then cause the pushrod to pull away from the device.
