Manufacturer Narrative

Device evaluated by mfr.: a visual examination of the balloon identified blood within the balloon which is consistent with a leak.Multiple hypotube kinks were noted along the hypotube shaft.Visual examination could not identify any kinks or damages.A detailed microscopic examination of the balloon material identified no tears or pinholes in the balloon.All blades were fully bonded on the balloon and did not exhibit any signs of damage.No issues identified during examination of the extrusion shaft.Tip showed no signs of tip damage.A microscopic examination of the proximal and distal markerbands identified no damage.The device was soaked in the water bath at 37 degrees celsius and was attached to an encore inflation device.An attempt was then made to inflate the balloon to 12atm as per, wolverine instructions for use (ifu) using an inflation aid attached however, pressure was unable to be maintained as inflation liquid was observed leaking from a pinhole that was 2mm proximal from proximal markerband.The encore inflation device was verified before and after the procedure using a druck gauge.
