Manufacturer Narrative

Device evaluated by manufacturer: the device was returned for analysis.A visual and microscopic examination of the balloon found no tears or holes in the balloon material.The returned device was attached to an encore inflation unit and the balloon was inflated.The balloon fully inflated and maintained pressure with no leaks noted.Using the same encore, a vacuum was pulled and the balloon deflated with no resistance noted.The balloon was inflated on two more occasions and the balloon maintained pressure for 30 seconds before a vacuum was pulled.No leaks were noted in the balloon.The encore inflation device was verified before and after use.No damage was observed to any of the blades.All blades were fully bonded onto the balloon.A visual and tactile examination found no issues with the hypotube of this device.The markerbands and tip and of the device 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 wire lumen identified no damage.A 0.014inch size wire was inserted through the wire lumen, prior to attempts to inflate the balloon, with no resistance noted.
