E1: initial reporter address 1: (b)(6).The wolverine cb mr, ous 10mmx2.25mm, catheter was returned for analysis.A visual and tactile examination of the hypotube identified multiple hypotube kinks at several locations along the hypotube shaft.A visual and microscopic examination identified that the balloon was returned in a deflated state.The balloon had been subjected to positive pressure.Three blades were present on the balloon surface however blade damage was noted on one blade.The proximal blade segment of blade one was found to be lifted but still attached.No damage was noted with the pad of the blade, and it was fully adhered to the balloon material.No issues were noted with blades two and three.A visual and tactile examination identified inner shaft damage (stretching) approximately 5cm proximal to the distal tip.An examination of the tip section found no issues.A visual and microscopic examination found no issue with the marker bands.
