Event Description
|
It was reported that a balloon rupture occurred.The 90% stenosed target lesion was located in the mildly tortuous and severely calcified from proximal to mid left anterior descending artery.A 15mmx2.50mm wolverine coronary cutting balloon was selected for use.During the procedure, it was noted that the balloon ruptured upon second inflation at 12 atmospheres for 10 seconds and that the blade was bent.The balloon was completely removed and the procedure completed with another of the same device.No complications were reported and the patient was good post procedure.

Manufacturer Narrative

Device evaluated by mfr: the device was returned for analysis.A visual examination of the balloon and inflation lumen identified no issues.The returned device was attached to a boston scientific encore inflation unit and positive pressure was applied to inflate the balloon and liquid was observed to be leaking from a balloon pinhole located at 5mm proximal from the distal marker band.The markerbands and tip section of the device were visually and microscopically examined, and no issues were noted with the markerbands or tip of the device that may have potentially contributed to the complaint incident.The blades of the device were visually and microscopically examined.Blade 1: mid and distal blade segments had areas of lift from pad visible at break points and blade segments were bent.Blade 2: middle blade segment was lifted from pad at distal end and all blade segments were found to be bent.Blade 3: proximal blade segment was bent, and distal blade segment lifted from pad at break point.The blade damages most likely occurred when the device met resistance of a challenging tortuous anatomy and challenging calcified stenosed lesion.A visual and tactile examination found multiple kinks on several locations of the hypotube shaft.This type of damage is consistent with excessive force that could have been applied on the delivery system.A visual and tactile examination found no issues with the extrusion shaft of the device which may have potentially contributed to the reported incident.No shaft kinks were noted.No other issues were identified during the product analysis.
