It was reported that removal difficulty was encountered and shaft break occurred.Vascular access was obtained using ipsilateral retrograde approach.The 99% stenosed target lesion was located in the moderately tortuous and moderately calcified iliac vessel.A 4fr introducer and a non-bsc guide wire were passed through radial approach respectively.A 4mm x 40mm x 146cm coyote es balloon catheter was used for dilatation.The balloon was deflated but upon removing the device, the device was trapped with the wire at the upper arm.The devices were removed with excessive force together as a unit and it was noted that the guide wire accordianed.However, it was noticed that 20cm from the tip of the balloon got detached and remained inside the body.The patient was then sent for surgery and the broken fragment was successfully removed.An epic stent was deployed in the target lesion.No further patient complications were reported.

It was reported that removal difficulty was encountered and shaft break occurred.Vascular access was obtained using ipsilateral retrograde approach.The 99% stenosed target lesion was located in the moderately tortuous and moderately calcified iliac vessel.A 4fr introducer and a non-bsc guide wire were passed through radial approach respectively.A 4mm x 40mm x 146cm coyote es balloon catheter was used for dilatation.The balloon was deflated but upon removing the device, the device was trapped with the wire at the upper arm.The devices were removed with excessive force together as a unit and it was noted that the guide wire accordianed.However, it was noticed that 20cm from the tip of the balloon got detached and remained inside the body.The patient was then sent for surgery and the broken fragment was successfully removed.An epic stent was deployed in the target lesion.No further patient complications were reported.Device evaluated by manufacturer: the returned product consisted of a coyote es balloon catheter with a stopcock,.014" guide wire, and introducer sheath.The outer shaft, inner shaft, balloon and tip were visually and microscopically examined.Visual examination revealed that the hypotube is separated 26.5cm from the tip and appears to be stretched prior to separation.There are multiple kinks along the whole device.Microscopic examination revealed a circumferential tear 10mm from the tip.There is blood present in the inflation lumen and balloon.The balloon is loosely folded.Review of the product specification indicates that all device models must be compatible with 4f introducer sheaths.The guidewire that returned with the balloon was inserted into the introducer sheath that also came back with the balloon.Then the separated distal section of the balloon was functionally tested and the balloon could follow the guidewire through the introducer sheath without any resistance.Inspection of the remainder of the device presented no other damage or irregularities.
