Abstract
The present application provides a connecting and releasing structure for a balloon system, a balloon system comprising the connecting and releasing structure, and a method for fabricating the same. The connecting and releasing structure is used for connection and release of a catheter and a balloon. The connecting and releasing structure comprises a self-sealing valve positioned on the balloon. The self-sealing valve comprises a catheter connecting port. The catheter passes through the catheter connecting port and is sealedly connected to the self-sealing valve. The self-sealing valve is completely or partially bonded to the inner wall of the balloon. When the catheter is removed after delivery of a filler, the self-sealing valve is not pulled out of the balloon, and thus leakage of the filler can be prevented. In addition, the perimeter of a small orifice in a side wall of the self-sealing valve or the perimeter of the cross-section of the distal end thereof is not greater than the outer diameter of the catheter, and therefore, no leakage occurs when the balloon is full of filler. In addition, the perimeters of cross-sections of the self-sealing valve may differ and increase gradually or stepwise from distal to proximal, thus facilitating the insertion and removal of the catheter.
