Manufacturer Narrative

Device evaluated by manufacturer: the device was returned for analysis.Based on the potential hazards/failure modes identified, the following attributes were examined: a visual examination identified that the balloon was in a deflated state.No issues were noted with the balloon of the device that may have potentially contributed to the complaint incident.The marker bands and blades and tip section of the device were visually and microscopically examined, and no issues were noted with the marker bands, blades or tip of the device that may have potentially contributed to the complaint incident.All blades were present and fully bonded to the balloon material.A visual and tactile examination of the hypotube identified no kinks or damages.The device was received in two sections as a result of a break in the distal extrusion.The break in the wire lumen was located at 7cm proximal from the tip.The distal break section (7cm in length) was severely stretched down and trapped on a section of the guidewire.Using a snap gauge the outer diameter of the returned guidewire was measured to be within specification at 0.0135").The distal outer was severely stretched.No other issues were identified during the product analysis.
