Age at time of event: 18 years or older.(b)(4).Device evaluated by manufacturer: the device was returned for analysis.A visual examination identified that the balloon was not folded which indicates that the balloon was subjected to positive pressure.Blood was identified within the balloon and inflation lumen which is evidence of a device leak.The returned device was attached to an encore inflation unit.Positive pressure was applied when liquid was observed to be leaking from a balloon pinhole located approximately at the distal edge of the proximal markerband.An examination of the balloon material and proximal markerband identified no issues which could potentially have contributed to this complaint.A visual and microscopic examination observed no damage to the tip or blades.All blades were present and fully bonded to the balloon surface.No kinks or damage were noted along the shaft of the device.The manufacturing batch record review confirmed that the device met all material, assembly and performance specifications.The investigation conclusion is operational context as the product meets the design & manufacture specification but due to anatomical/procedural factors encountered during the procedure, performance was limited.(b)(4).

It was reported that a balloon leak and a balloon rupture occurred.The 90% stenosed target lesion was located in the moderately tortuous and mildly calcified distal right coronary artery.A 10/3.00 flextome¿ cutting balloon¿ was selected for use.During the procedure, pressure was applied at 6atm.However, it was observed that leak of contrast media occurred in the distal part of the balloon.When the device was removed from the patient's body, the balloon was found to be ruptured.The procedure was completed with a different device.No patient complications were reported.
