Manufacturer Narrative

Device evaluated by manufacturer: the device was returned for analysis.A visual and microscopic examination identified that the balloon was folded.No damage was observed along the entire balloon.All blades were intact within their pads and fully bonded to the balloon material.The device was received in two sections as a result of a break which occurred in the hypotube shaft.The break was located at 13.7cm distal from the strain relief.The distal section of the hypotube break was kinked at 0.2cm and 0.4cm distal from the break site.A visual and tactile examination of the distal extrusion identified no damage.The markerbands were visually and microscopically examined, and no issues were noted with the device that may have potentially contributed to the complaint incident.An examination of the tip section of the device identified no damage.
