The device was not returned for evaluation.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history identified no other complaints reported from this lot.Based on the information provided, the difficulty removing, and subsequent twisting of the barewire tip appears to be due to circumstances of the procedure.It is likely that clearance between the inner diameter of the non-abbott atherectomy device and outer diameter of the barewire became reduced during use, resulting in the devices becoming stuck together causing difficulty to remove and resulting in twisting of the barewire.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.
