Embodiment Construction

[0020] In the following, the present invention will be further explained through specific embodiments in conjunction with the drawings:

[0021] see figure 1 , An embodiment of a stent-equipped balloon catheter structure for vasodilation surgery, comprising an inner tube 7, a Y-shaped connector, a balloon 3 and a restraining stent 4. The restraining stent 4 is wrapped outside the balloon 3 and also includes a transition The connecting tube 6 and the braided tube 8, the transitional connecting tube 6 is located between the braided tube 8 and the balloon 3, the proximal part of the balloon 3 is wrapped outside the transitional connecting tube 6 and fixedly connected, and the distal part of the braided tube 8 is wrapped The two ends of the restraining stent 4 are respectively wrapped around the two ends of the balloon 3 and connected to each other. The Y-shaped connector includes a catheter operating handle 10 and a catheter reinforcement tube 9. The catheter reinforcement tube 9 is...

Abstract

The invention discloses a balloon catheter structure for a vasodilation surgery and with a stent. The balloon catheter structure comprises an inner tube, a Y-shaped connecting piece, a balloon and therestraining stent, and the restraining stent covers the balloon. The balloon catheter structure is characterized by further comprising a transition connecting tube and a weaving tube, the transitionconnecting tube is located between the weaving tube and the balloon, the near-end part of the balloon covers the transition connecting tube and is fixedly connected with the transition connecting tube, and the far-end part of the weaving tube covers the transition connecting tube and is fixedly connected with the transition connecting tube; the two ends of the restraining stent respectively coverthe two ends of the balloon and are fixedly connected with the balloon. By means of balloon catheter structure, the pushing and penetrating performance at a complicated lesion part is greatly improved, the connecting strength is improved, good structural supporting performance is provided, pushing is smooth, and the situation that the blood vessels are injured due to excessive expansion is avoided; the wall attaching performance of the balloon is good, the lesion part is effectively cut, smashed and taken out of the human body, and the focus of vascular stenosis and blockage is eradicated.

Description

Technical field [0001] The invention relates to the technical field of vascular interventional therapy, in particular to a stent balloon catheter structure for vasodilation surgery. Background technique [0002] The incidence of peripheral vascular disease has increased significantly in recent years, such as arterial stenosis, arteriovenous thrombosis, and aneurysm. At present, there are three main ways to treat peripheral vascular diseases: drug treatment, surgical treatment and interventional treatment. Interventional therapy has a better effect than medical treatment. Compared with surgical treatment, interventional therapy has less risk, fewer complications, and strong patient tolerance. [0003] At present, peripheral vascular interventional therapy mainly uses balloon angioplasty and vascular stent placement. Balloon vasodilation involves ballooning a balloon catheter through a guide wire to reach the diseased site and then performing balloon dilation to restore the stenosis...
