Manufacturer Narrative

Device evaluated by mfr.: the device was returned for analysis.A visual examination of the balloon identified no damages.A hypotube kink was identified 69.5cm distal to the distal end of the strain relief.Along the polymer extrusion there were multiple kinks.Microscopic examination of the balloon material identified no tears or pinholes in the balloon.However, when inflating the balloon, the inflation liquid was coming from the mid-section of the balloon.A detailed microscopic examination on the mid-section identified a tear 4mm distal from the proximal makerband.All blades were fully bonded on the balloon and did not exhibit any signs of damage.Multiple kinks were identified along the polymer extrusion.Tip showed no signs of tip damage.A microscopic examination of the proximal and distal markerbands identified no damage.The device was inflated to 12 atm as per instructions for use.Using the inflation aid, a leak was noted in the mid-section of the balloon.Microscopic examination identified a tear 4mm distal from proximal markerband.The encore inflation device was verified before and after the procedure using a druck gauge.
