Abstract

The invention relates to a spinous process balloon dilatation catheter which comprises a balloon, an outer tube and an inner tube coaxially arranged in the outer tube in a sliding mode. One end of the inner tube extends out of the outer tube to form an extending section, the balloon is arranged on the extending section of the inner tube, the extending section penetrates into the balloon, and the end, opposite to the outer tube, of the extending section is connected with one end of the balloon. The other end of the balloon is connected with the outer tube, a plurality of spinous process wires are arranged at the position of the balloon and wrap the balloon, a control piece is arranged between the spinous process wires and the balloon, and the two ends of each spinous process wire are clamped into the control piece and slide on the control piece in the length direction of the outer tube. The balloon catheter has the advantages that the spinous process wire is restored to the original position, so that the problems that the spinous process wire is clamped and hung in a blood vessel and the balloon catheter is clamped and hung by a lesion part or an indwelling stent and the like and is difficult to pull out when being taken out are solved, and the balloon catheter can be taken out more conveniently.

Description

technical field [0001] The invention relates to the technical field of balloon catheters, in particular to a spinous process balloon dilation catheter. Background technique [0002] Balloon dilatation catheter is a kind of medical interventional equipment, which can treat heart and blood vessel stenosis and dilation. Special balloon dilation catheters include cutting balloons and spinous process balloons. Among them, the coronary artery spine In the design of the balloon catheter, 3 nylon spinous processes are mounted on the surface of the balloon from the proximal end to the distal end, and the balloon slippage that may occur during the balloon expansion process is eliminated through the spinous processes. Elimination, thus obtaining a more excellent expansion effect. [0003] Then, during the use of this spinous process balloon, when the balloon is contracted to extract the balloon catheter from the body, the spinous process filaments often cannot be restored to their ori...
