It was reported that the dragonfly opstar imaging catheter was used in a long lesion in the circumflex (cx) artery with heavy calcification.However, upon catheter removal, a tear in the guide wire exit notch was suspected because the catheter was moving on its own without the wire and not tracking.There were no adverse patient effects and no clinically significant delay in the procedure.No additional information was provided.

Visual inspection and dimensional analysis were performed on the returned device.The reported material split, cut, or torn and material too soft/flexible (support) were unable to be confirmed.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 similar complaints were reported from this lot.Based on the information provided and analysis of the returned device, the cause of the reported material too soft/flexible (support) and alleged tear was unable to be confirmed.There were no anomalies on the catheter which could be directly attributed to the alleged torn sheath, nor for the reported material too soft/flexible (support).It is likely that either the patient¿s anatomical condition (heavy calcification) or use techniques caused the reported difficulties; however, this could not be confirmed.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.
