Event Description
|
It was reported that catheter entrapment on guidewire occurred.The 98% stenosed target lesion was located in the mildly tortuous and moderately calcified mid right coronary artery.A 30mm x 2.25mm nc quantum apex balloon catheter was advanced for dilatation.However, when the balloon was inflated above rated burst pressure at 26 atmospheres, the balloon lumen appeared to collapse and will not pull back off the guidewire easily.The physician deflated balloon entirely, and had extreme difficulty in trying to remove it from the guidewire.The procedure was completed with another of same device.There were no patient complications reported.

Manufacturer Narrative

Device evaluated by mfr.: returned product consisted of an nc quantum apex balloon catheter.The device was visually and microscopically examined.At 113.2cm from the strain relief, the shaft and hypotube of the device was kinked.There was contrast in the inflation lumen and the balloon.There was blood in the guidewire lumen, and the balloon was loosely folded.A guidewire passed through the device with no resistance or issues.The guidewire was inserted through both the exit notch and the tip of the device and encountered no difficulties.The device was wire tested with the same guidewire used to test prior.No resistance was found.The device was soaked in an uncontrolled warm temperature water bath to break up contrast and inflate the device.Upon inflation to 6atm, movement of the wire was tested, and resistance was met.The tip end of the wire had coiled segments and was met with resistance when pulled through the proximal portion of the guidewire lumen.No damage or defects were noted on the device.Product analysis did not confirm the reported event, because the guidewire passed through the device with no resistance or issues.During investigation, the wire-testing during inflation, the wire was met with resistance when attempting to advance and retract the wire.However, clinical circumstances could not be replicated.
