Manufacturer Narrative

Device evaluated by mfr: the device was returned for evaluation.A visual and tactile examination of hypotube shaft identified no damages.A visual examination of the distal extrusion identified no damages.A visual examination of the balloon identified that the proximal folds in the balloon were relaxed (not tightly folded).Microscopic examination of the inner/wire lumen identified no damages.A detailed microscopic examination of the balloon material identified no damages.A microscopic examination of the balloon identified that the proximal folds in the balloon were relaxed (not tightly folded).All blades were fully bonded on the balloon and did not exhibit any signs of damage.A microscopic examination of the tip section found no issues.The device was attached to a pre-tested encore inflation device (tested using the druck pressure gauge) and the balloon was inflated to its rated burst pressure (rbp) of 12 atmospheres (per instructions for use) with no leaks noted.A vacuum was applied, and the balloon deflated fully.Although the balloon deflated fully the balloon did not rewrap/refold.This is not a defect with the balloon.No other issues were identified during the product analysis.
