Event Description
|
It was reported that a device difficulty removal and fracture occurred.The stenosed target lesion was located in the left anterior descending artery (lad).A 10mmx2.75mm wolverine coronary cutting balloon was selected for use.During the procedure, the device was attempted to use in left anterior descending artery and had a great resistance when inserting it into the guidewire.They tried to remove the catheter, but extreme resistance was encountered, and the catheter was separated outside the y-connector.The remainder of the device was removed along with the entire guidewire.The procedure was completed with another of the same device.There were no patient complications reported port procedure.

E1.Initial reporter city: (b)(6).The device was returned and evaluated by manufacturer.Only approximately 4.4cm in length of the distal end of the device was received, including a section of the distal end of the extrusion, the balloon, markerband and tip, loaded on a guidewire.An examination of the distal extrusion showed the extrusion was severely stretched down onto the guidewire.A microscopic examination of the distal extrusion found that the inner and outer lumens were severely stretched.The inner lumen was pulled distally inside the balloon.As a result of this damage the inner lumen was bunched on either side of the distal markerband.A detailed microscopic examination of the balloon material identified no damages.All blades were fully bonded on the balloon and did not exhibit any signs of damage.A microscopic examination of the tip section found no damages.A microscopic examination of the actual markerbands identified no damages.However, due to the inner lumen being pulled distally inside the balloon, the proximal markerband was positioned towards the distal markerband.The outer diameter of the guidewire was measured to be within specification at 0.014inch.An attempt to remove the distal section of the device from the wire failed as the device section was severely stretched down onto the wire.
