Abstract

The present invention provides a medical balloon and its manufacturing method and balloon dilatation catheter. The balloon has a smaller contour diameter after decompression. Another purpose of the present invention is to make the balloon have better passage through the lesion at the same time. capacity of the part. The medical balloon of the present invention comprises a balloon cone and a straight section of the balloon, and on the straight section of the balloon, a plurality of protruding longitudinal ribs are distributed at intervals along the circumferential direction. The longitudinal ribs may be formed by applying a strip of coating to the straight section of the balloon.

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 the statistics of the World Health Organization, chronic diseases such as heart disease have become the main cause of death for human beings, accounting for more than 60% of the total annual death toll, among which coronary heart disease patients are the most common. Angioplasty (PCI) is an effective method for treating 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, and dredges the diseased blood vessel.

[0003] The balloon dilatation catheter is composed of a balloon with dilatability at the distal end and a proximal tube section. When the balloon part of the balloon dilation catheter is pushed to the lesion, the balloon will be...
