E1 - initial reporter city: (b)(6).Device evaluated by mfr: the device was returned for evaluation.A visual examination identified that the balloon was not folded which indicates that the balloon was subjected to positive pressure.The returned device was attached to an encore inflation unit and positive pressure was applied in an attempt to inflate the balloon.Liquid was observed to be leaking from a balloon pinhole located at 5mm distal to the proximal marker band at the site of a blade segment lift.An examination of the balloon material and markerbands identified no issues which could potentially have contributed to this complaint.The rated burst pressure for this device is 12 atmospheres.One blade found to be lifted out of its pad at the break point.Pad and remaining blade segment found to be secured to the balloon material surface.No issues identified with any other blades.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.
