It was reported that balloon incorrect length occurred.A 2.50mm x 12mm emerge balloon catheter was advanced for dilatation.However, during procedure the balloon appears longer under fluoroscopy than the stated 2.50mm x 12mm length.The balloon was inflated several times over rated burst pressure to 20 atmospheres.The procedure was completed with this device.No patient serious injury or adverse event were reported and the patient's status was fine.Device evaluated by manufacturer: the returned product consisted of an emerge balloon catheter.The shaft, hypotube, tip and balloon were microscopically and visually examined.There was contrast in the inflation lumen and balloon.The balloon was loosely folded.There were numerous hypotube kinks throughout the device and the tip was damaged.Functional testing was performed by placing a test guidewire in the wire lumen and connected an inflation device filled with water to the inflation port to emerge device.The device was inflated to nominal pressure and was microscopically inspected.The balloon was found to be deformed/stretched and the wire lumen was found to be stretched.The balloon was measure with a stainless steel ruler and found to be approximately 16mm.The deform/stretching of the balloon and inner shaft is consistent to damaged caused by over inflating the device several times.Inspection of the remainder of the device presented no other damage or irregularities.
