Manufacturer Narrative
|
Device evaluated by manufacturer: the device was returned for analysis.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 in an attempt to inflate the balloon and liquid was observed to be leaking from a balloon pinhole located at the site of the proximal marker band.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 as per wolverine label specification.All blades were intact within their pads and fully bonded to the balloon material.A visual and tactile examination found no kinks or damage tom the hypotube or shaft of the device.The markerbands and tip and of the device were visually and microscopically examined, and no issues were noted with the device that may have potentially contributed to the complaint incident.No other issues were identified during the product analysis.
