Abstract

A medical balloon (1; 2; 3; 4; 5) and a manufacturing method therefor. The medical balloon (1; 2; 3; 4; 5) has a relatively small contour diameter after the pressure of the balloon is released, and has a good capability of passing through a diseased region. The medical balloon (1; 2; 3; 4; 5) comprises a balloon conical portion (121, 122) and a balloon straight segment (11). The balloon straight segment (11) is circumferentially provided with multiple raised longitudinal ribs (13; 21, 22, 23; 311, 312, 313; 411, 412; 511, 512, 513) arranged spaced apart from one another. The longitudinal ribs (13; 21, 22, 23; 311, 312, 313; 411, 412; 511, 512, 513) can be formed by coating a strip-shaped coating layer onto the balloon straight segment (11).

Description

Technical field

[0001] The invention relates to a medical balloon, a manufacturing method thereof, and a balloon expansion catheter. Background technique

[0002] According to statistics from the World Health Organization, chronic diseases such as heart disease have become the main cause of death in humans, accounting for more than 60% of the total annual deaths, especially coronary heart disease patients. Angioplasty (PCI) is an effective method for the treatment of various vascular diseases. It is a minimally invasive technique that inserts a balloon catheter into the diseased blood vessel through percutaneous puncture of the patient's peripheral artery, dilates the narrowed lesion site, and unblocks the diseased vessel.

[0003] The balloon dilatation catheter is composed of a balloon with expansion capability at the distal end and a proximal tube segment. When the balloon part of the balloon dilatation catheter is pushed to the lesion, the balloon is expanded by liquid pressur...
