Event Description

It was reported that a balloon rupture occurred and a portion of the blade was left inside the patient.The 90% stenosed target lesion was located in the moderately tortuous and severely napkin-ring like calcified artery.A 10mmx3.00mm wolverine coronary cutting balloon was selected for use.During the procedure, the physician decided to apply high pressure and lesion was dilated at 24atm; however, it was noted that the balloon was inflated beyond the rated pressure and ruptured at that moment.Furthermore, the balloon was stuck in the lesion and it was suspected that the distal site of the blade was stuck in the calcification.Consequently, the balloon was removed using a guide extension catheter.When the device was checked outside patient's body, it was noted that the tip part of one blade out of three was missing.Ivus was then performed and the detached portion was seen immersed/floating in the lesion area.Thus, the detached portion was covered with a stent.No further patient complications were reported and the patient was good post procedure.

Initial reporter city: (b)(6).The device was returned for evaluation.A visual and microscopic examination was performed on the returned device.It was noted that a section of one of the blades, approximately 5mm in length was completely detached from the distal end of the blade.The remaining section of blade was undamaged and fully bonded to the balloon material.The complete pad of the blade remained fully bonded to the balloon material.The detached section of blade was not returned for analysis.The damage identified can potentially be a result of the resistance encountered during use of the device.All other blades were intact and fully bonded to the balloon material.A visual examination identified that the balloon was not folded which indicates that the balloon was subjected to positive pressure.A microscopic examination identified a balloon longitudinal tear beginning approximately 1mm proximal of the distal tip and extending approximately 8mm across the balloon material.An examination of the balloon material and markerbands identified no issues which could potentially have contributed to this complaint.A visual and tactile examination found no kinks or damage to the hypotube of the device.A visual examination identified no damage to the tip of the device.No other issues were identified during the product analysis.
