Event Description
|
It was reported that a balloon rupture occurred and half of the blade went missing.The 90% stenosed target lesion was located in the moderately tortuous and severely calcified mid right coronary artery.A 10mmx3.75mm wolverine coronary cutting balloon was selected for use.During the procedure, the balloon ruptured at 12 atmospheres for 10 seconds upon third inflation.The device was then able to be pulled out with the usual method with a little resistance.However, half of the blade was noted to be missing and the possibility of it remaining inside the body cannot be denied.Furthermore, the blade was lifted.The procedure was completed with a different device.No complications reported and the patient is in good condition after the procedure.

E1.Initial reporter city- (b)(6).Device evaluated by manufacturer: the device was returned for analysis.A visual examination identified that the balloon was in a deflated state.The returned device was attached to an encore inflation unit and positive pressure was applied in an attempt to inflate the balloon.Liquid was observed to be leaking from a balloon pinhole located the balloon mid-section.An examination of the balloon material and marker bands identified no issues which could potentially have contributed to this complaint.Four blades were present on the balloon surface however, the following blade damage was noted on two blades: blade 1: blade lift was noted on the proximal blade segment and no issues were noted with the pad of this blade.It was fully adhered to the balloon surface.Blade 2: the proximal blade segment was found to be missing from its pad.The blade pad was found to be fully adhered to the balloon surface.No issues were noted with blade 3 or 4.A visual and tactile examination identified no issues noted on the hypotube.A visual and tactile examination identified no issues on the shaft polymer extrusion.The marker bands and tip and of the device were visually and microscopically examined, and no issues were noted with the device that may have potentially contributed to the complaint incident.
