It was reported that the balloon was difficult to remove and balloon rupture occurred.A 10mm x 3.00mm wolverine coronary cutting balloon was selected for use.During procedure, severe resistance was met during removal and the device could not be removed.The physician cut the hub of the wolverine and a guideliner was inserted over the wolverine balloon and pulled out to remove it.A hole in the balloon was also noticed on the device.No patient complications were reported.

Manufacturer Narrative

E1: initial reporter address 1:(b)(6).Device evaluated by mfr: the device was returned for evaluation.A visual examination identified that the balloon was returned in a deflated state.The balloon had been subjected to positive pressure.3 blades were present on the balloon surface however the following blade damage was noted: blade 1 - 1 mm of the distal blade segment was missing (missing from break point extending to 1mm in a distal direction).Blade pad remained secure to balloon material.Blade 2 - full distal blade segment missing from pad - pad remains secure to balloon material.Blade 03 - no issues noted.Device returned with hub removed.Shaft polymer extrusion found to be stretched at the guidewire port.No issues were noted with the tip of the device.A visual and microscopic examination found no issue with the markerbands.
