Embodiment 1

[0023] figure 1 A schematic structural diagram of a balloon dilatation catheter provided in an embodiment of the present application.

[0024] Such as figure 1 As shown, the balloon dilatation catheter includes: a balloon 1, a push rod 2, an inner tube 3, a developing mark 4, a stress diffusion tube 5 and a connecting device 6, wherein: the push rod 2 is a hollow structure, and the distal end is connected to the balloon 1 Sealed and fixed, the proximal end is sealed and fixed with the connecting device 3; the inner tube 4 is also a hollow structure, which runs through the inner cavity of the balloon 1 and the push rod 2, and its distal end passes through the balloon 2 and is sealed and fixed with the balloon 2 , the proximal opening is sealed and fixed with the end opening of the push rod 2, and the proximal opening of the inner tube 4 communicates with the outside world; The injection hole 7 is used for injecting liquid or gas into the balloon 1 to expand the balloon 1 duri...

Embodiment 2

[0029] In the embodiment of the present application, the proximal opening of the inner tube of the balloon dilation catheter can be arranged not only at the proximal opening of the push rod, but also on the side wall of the push rod.

[0030] image 3 A schematic structural diagram of another balloon dilatation catheter provided for the implementation of this application.

[0031] Such as image 3 As shown, the balloon dilatation catheter includes: a balloon 1, a push rod 2, an inner tube 3, a developing mark 4, a stress diffusion tube 5 and a connecting device 6, wherein a side port 9 is opened at an appropriate position outside the push rod 2 , the proximal end of the inner tube 3 is sealed and fixed to the side port 9, and both ends of the inner tube 3 communicate with the outside world. The connection relationship of other parts is the same as that of Embodiment 1 of the present application.

[0032] In actual use, the balloon dilation catheter is used for pre-dilation ...

Abstract

The invention discloses a percutaneous transluminal coronary angioplasty (PTCA) balloon catheter, which comprises a push rod, a balloon, an internal tube, a developing mark, a stress diffusion tube and a connecting device, wherein a plurality of bumps are arranged on the outside surface of the balloon. The outside surface of the balloon of the PTCA balloon catheter provided by the embodiment of the invention has a plurality of bumps, so that the bumps can tightly adhered onto the blood vessel walls of blood vessels at lesions in an interventional treatment operation to provide enough friction to prevent the balloon from sliding and displacing in or after expansion; and thus, the operation is safe and stable.

Description

technical field [0001] The present application relates to the field of medical devices, in particular to a balloon dilatation catheter. Background technique [0002] In the past ten years, with the aggravation of my country's aging population and the increase in the incidence of diabetes, the prevalence of cardiovascular and cerebrovascular and peripheral blood vessels has also been increasing. In vascular diseases, arterial stenosis will directly endanger the life safety of patients. . [0003] At present, there are three main ways to treat arterial stenosis: conservative drug treatment, surgery and interventional therapy. Conservative drug treatment cycle is long, poor curative effect and other shortcomings. Traditional surgical operations have large trauma, many complications, and long hospital stays, which are unbearable for many patients. Interventional surgery (arterial balloon dilatation surgery and stent implantation) is a diagnosis and treatment operation performe...
