Abstract
The present disclosure provides double-lumen closure balloon catheter, including an inner tube and an outer tube. A distal end of the inner tube extends from a distal end of the outer tube, the inner tube is provided at its distal end with a tubular hydrophobic tip through which air passes, a cavity of the hydrophobic tip is in communication with a cavity of the inner tube, the outer tube is provided at its distal end with an expandable or shrinkable balloon, a proximal end of the balloon is hermetically coupled to the distal end of the outer tube, a distal end of the balloon is hermetically coupled to the hydrophobic tip, and a channel in communication with an inner cavity of the balloon is arranged between the inner tube and the outer tube. The present disclosure further provides a using method thereof. As compared with the related art, the liquid is injected into the channel so as to push air in the inner cavity of the balloon and the channel to the hydrophobic tip and then discharge air in the cavity of the hydrophobic tip through the wall of the hydrophobic tip. As a result, it is able to prevent the balloon from being damaged, and facilitate the operation, thereby to reduce the time for the surgery.
