Manufacturer Narrative

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, the balloon was inflated to its rate of burst pressure of 12 atmospheres without issue.A vacuum was then applied.The inflation device was verified at 12 atmospheres, before and after use with a calibrated pressure gauge.This inflation to rate of burst pressure of 12 atmospheres was repeated three times with no leaks or drop in pressure noted.No issues were identified with balloon inflation or the balloon material.No issues were noted with the tip section of the device.A visual and microscopic examination found no issue with the markerbands.A visual and tactile examination found that the shaft was severely kinked at approximately 10mm proximal of the guidewire port.This is consistent with excessive force being applied to the device.No issues were identified during the product analysis.
