Manufacturer Narrative
|
Device evaluated by manufacturer: the device was returned for analysis.Two balloon protectors were received with the returned device.The both of the returned balloon protector's inner dimensions were verified at 0.0435 inch using a pin gauge.This is within the specified range of 0.0420 inches to 0.0435 inches 'balloon protector 3.5mm thru 4mm'.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 inflation lumen which is evidence of a device leak.The returned device was attached to a boston scientific encore inflation unit.Positive pressure was applied when liquid was observed to be leaking from a balloon pinhole located approximately 2mm distal to the distal end of the proximal markerband.An examination of the balloon material and proximal markerband identified no issues which could potentially have contributed to this complaint.The rated burst pressure for this device is 12 atmospheres as per spcb flextome specification.A visual and tactile examination identified with the hypotube or shaft of the device.
