A visual inspection was performed on the returned balloon catheter; however, the reported difficulty to advance/position and difficulty to removed unable to be confirmed due to the returned condition of the device.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 incidents and/or complaints reported from this lot.Factors that may contribute to the difficulty to advance/position and remove the guide wire and cause resistance between the devices may include, but not limited to, device placement technique, guiding catheter support, anatomical conditions, inner diameter of guide wire lumen or delivery device, outer diameter of the guide wire, condition of the guide wire, condition of the balloon catheter, coagulation of blood or procedural contaminates.The investigation was unable to determine a conclusive cause for the reported difficulty to advance/position and difficulty to remove the guide wire.In this case, it may be possible that the guide wire was damaged during advancement through the anatomy causing damage to the inner layers of the inner member resulting in the difficulty to advance/position the wire and ultimately causing the wire to become frozen in the guide wire lumen; 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.
