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.Blood was identified within the balloon and lumen which is evidence of a device leak.The returned device was attached to an encore inflation unit and positive pressure was applied in an attempt to inflate the balloon.The balloon could not be inflated due to the presence of solidified blood that was present within the inflation lumen.The device was soaked in a water bath at a temperature of 37 degrees celsius to help soften the blood before further inflation attempts were made.The device was removed from the bath and the balloon was again attached to an inflation device subjected to positive pressure, but the investigator was still unable to inflate the device.A microscopic examination identified a balloon pinhole located approximately 2mm proximal of the distal markerband.An examination of the balloon material and distal markerband identified no issues which could potentially have contributed to this complaint.The rated burst pressure for this device is 12 atmospheres.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 no issues or damage to the shaft or hypotube of the device.No other issues were identified during the product analysis.
