Event Description

It was reported that a balloon rupture occurred.The 50% stenosed target lesion was located in the moderately tortuous and mildly calcified proximal of left anterior descending artery (lad).A 15mmx3.50mm wolverine coronary cutting balloon was selected for use.During the procedure, a 3.0 mm non boston scientific stent was placed in the middle part of the lad.Inflation was then performed three times at 8 atm, 20 atm, and 20 atm with the tip inserted from the proximal part to the middle part of the target lesion.When an attempt was made to perform the fourth inflation, the balloon did not inflate, and when the device was checked outside the body, it was found that the balloon ruptured.The physician's comment was it was caught in the strut of the stent at the distal part.The procedure was completed with this device.No patient complications reported.

Device evaluated by mfr.: the device was returned for analysis.Multiple kinks were identified along the hypotube shaft.A visual and tactile examination identified no damages in the shaft polymer extrusion.A visual examination identified that a few blades lifted and detached.A detailed microscopic examination of the balloon material identified no issues.The balloon was returned in a deflated state.No issues identified during examination of the extrusion shaft.Blades: a microscopic examination of the blade segments identified the following: blade 1: one section of the proximal blade segment (approximately 4mm) was missing.The pad was fully bonded onto the balloon.Blade 2: about 2mm of a blade segment was not returned, the proximal part of the blade was bonded onto the pad and balloon.Blade 3: one segment of the blade and pad was lifted.Blade 4: a blade was lifted from the balloon in the proximal section.A microscopic examination of the tip section found no damage.The device was attached to an encore inflation unit and the balloon was inflated to its rated burst pressure of 12 atmospheres with no leaks or damages.Encore device verified before and after use using the druck gauge.No other device issues were identified during returned product analysis.
