Problems solved by technology

[0005] On the other hand, during the retraction process after the balloon is inflated, the profile diameter (profile) of the balloon after decompression is too large, which is likely to cause damage to the vessel wall and displacement of the stent after implantation, reducing the curative effect of the operation
Finally, although the one-time use of medical devices significantly reduces the risk of infection, it also leads to an increase in the cost of patient treatment, and how to improve the multiple use rate of medical devices in the same patient treatment will be an effective solution

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...
