Device evaluated by manufacturer: the device was returned for analysis.A visual and microscopic examination was performed on the returned device.All four blades were present and fully attached to the balloon as per wolverine specification.No issues were noted with the blades.A visual examination identified that the balloon was not folded which indicates that the balloon was subjected to positive pressure.Blood was identified within the balloon and lumen which is evidence of a device leak.The returned device was attached to a boston scientific 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 3mm proximal of the distal markerband.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.A visual examination identified no issues with the tip.A visual and tactile examination identified no issues.A visual and tactile examination found the hypotube of the device to be kinked at more than one location.No other issues were identified during the product analysis.
