Device now available for evaluation on 4 may 2018.Device evaluation: evaluation completed on 10 may 2018.A kink was present at the distal end of the device from return packaging.Patency was checked with 0.035" guide wire.Distal to hub: resistance was noted at hub from tube to hub, but guide wire does pass.Red biological material was present.A 60 ml syringe was used to fill the balloon with air.At first the device slowly inflated but was failing to expand.Filled a tub with water to inflate balloon under water; results were bubbles seen at the proximal end of the balloon on the cone transition.Device re-evaluation completed on 25 may 2018.The device was imaged using a scanning electron microscope.The photos showed the external surface of the balloon was mechanically damaged, which was the catalyst for failure (initial complaint stated that a small leak was noted on the balloon as the physician and scrub tech chose to inflate the balloon for hands-on experience with deployment post-procedure; it was also reported that the balloon had been sitting on the scrub table with suture needles and other open supplies).
