As reported: while trying to advance and retrieve the trapliner through the 8f inside a guide catheter to allocate the tip into the right rca (right coronary artery), it suddenly broke and disconnected.Thetrapliner was retrieved in the guide catheter and the procedure went on without trapliner.Patient outcome is reported as well, with no problems.

Trapliner was returned for evaluation.Device history record was reviewed.There are no non-conformances related to this lot, therefore, supporting the device met material, assembly and performance specifications.The catheter pushwire was separated at the weld joint.The distal coils were herniated which is consistent with advancing/withdrawing against resistance.The ifu, states the following warning, "never advance, withdraw, or rotate an intravascular device against resistance until the cause of the resistance is determined by fluoroscopy.Movement of the catheter against resistance may result in separation of the catheter or guidewire tip, other device damage, or vessel injury." also, per ifu" exercise care in handling the catheter during a procedure to reduce the possibility of accidental breakage or kinking.Do not apply torque to the catheter during delivery, as catheter damage may result".Based on the returned product evaluation, the most likely root cause of the issue is operational context and/or unintended use error.
