The device history record review confirms that the device met all material, assembly and performance specifications.Visual inspection revealed that the balloon catheter shaft was kinked at approximately 16.0cm from its distal end.The catheter was accordion wrinkled on its distal shaft and on its proximal shaft and was full of procedural fluid.The balloon was examined under magnification and it was observed that the balloon was ruptured (punctured).No other anomalies were observed.During inflation testing,balloon failed to inflate with air because of the perforation/holes in the balloon and the leaked with water.Information available indicated that the device was confirmed to be in good condition prior to use,continuous flush was maintained, resistance was felt when advancing the balloon into the vessel, and the anatomy was very tortuous.It is probable that the patient's tortuous anatomy contributed to difficulties advancing the device which led to the reported and analyzed damages.Based on the information currently available, it is probable that some procedural factors encountered during the procedure limited the performance of the balloon catheter contributing to the reported and observed damages.Therefore, an assignable cause of component failure has been assigned to this investigation.
