It was reported that entrapment of device occurred.The 80% stenosed target lesion was located in mildly tortuous and mildly calcified mid left anterior descending artery.A 20mm x 2.50mm nc quantum apex was advanced for dilatation and inflated to 20 atmospheres.However, during the procedure, the device got stuck on a non-boston scientific guidewire.The balloon and guidewire were both removed from the patient's body simultaneously as one unit.It was noted that the balloon was deflated prior to removal and was removed from the patient intact.The procedure was completed with another of same device.There were no patient complications reported.

Device evaluated by mfr.: returned product consisted of an nc quantum apex balloon catheter.The device was visually and microscopically examined.There was blood and contrast present in the manifold, inflation lumen and the balloon.There was blood in the guidewire lumen, and the balloon was loosely folded.At 3mm from the tip, moving proximally for a length of 12mm, there was a longitudinal tear in the balloon.The guidewire used in the procedure was not returned for analysis, so a test 0.014 guidewire was used for functional testing.The guidewire passed through 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 guidewire passed through the device with no resistance or issues, however, clinical circumstances could not be replicated.The unreported longitudinal tear is damage that could occur during procedural use due to an interaction with patient characteristics, over inflation, or an interaction with another device.
