Event Description
|
It was reported that a balloon rupture occurred.The 99% stenosed target lesion was located in the moderately tortuous and severely calcified proximal left anterior descending artery.A 10mmx3.00mm wolverine coronary cutting balloon was selected for use in a tight lesion.During the procedure, it was noted that the balloon ruptured upon inflation at 6atm for 1 second and the contrast agent has leaked due to balloon rupture.The device was removed using normal method without issue and the procedure was completed with a different device.No complications were reported and patient was good post procedure.

E1 - initial reporter facility name: (b)(6) hospital.Device evaluated by mfr.: the device was returned for analysis.A visual examination of the balloon identified no damages.No issues identified with the hypotube shaft.Shaft polymer extrusion: no kinks or damages.A detailed microscopic examination of the balloon material identified no tears or pinholes in the balloon.All blades were fully bonded on the balloon and did not exhibit any signs of damage.No issues identified during examination of the extrusion shaft.Tip showed no signs of tip damage.Using an encore inflation unit (tested before and after use with druck pressure gauge, the balloon was inflated to its rated burst pressure (rbp) of 12 atmospheres (atm).The balloon inflated fully and maintained pressure for 15sec, with no leaks noted.A vacuum was applied and the balloon deflated fully with no resistance.The balloon was inflated to its rbp on three more occasions with no leaks noted.No issues were identified with balloon inflation or the balloon material.
