Problems solved by technology

[0011] Problem 2: The current drug balloon design cannot exceed the release time of 60s, because too long filling in the coronary artery can easily cause ischemia and necrosis of the distal myocardium, resulting in an irreversible situation

Abstract

The invention discloses a drug-loading balloon instrument. The drug-loading balloon instrument comprises a catheter, an inner membrane and an outer membrane, wherein the inner membrane is located on the radial outer side of the catheter, a fixed connection part is arranged at the part of the inner membrane, a moving part is at least arranged at the rest part of the inner membrane except the fixedconnection part, and the fixed connection part is fixedly connected with the outer wall of the catheter; a full balloon cavity is formed between the outer membrane and the inner membrane, and at leastone drug-loading cavity which is formed before the full balloon cavity is full and loaded with a drug inside and expands after the full balloon cavity is full is formed in the outer wall of the outermembrane; and the moving part moves towards the radial outer side of the catheter in the filling process of the full balloon cavity to form a hollow channel for blood stream to pass with the catheterafter the full balloon cavity is completely full. The drug-loading balloon instrument realizes the ultrahigh wall adhering rate of the drug in blood vessels and plays a great role in reducing the occurrence rate of postoperative coronary artery restenosis.

Description

technical field [0001] The invention relates to a drug-loaded balloon device, which belongs to the technical field of medical devices. Background technique [0002] At present, with the aging of the population and the change of dietary structure, arterial occlusive diseases (heart, brain, internal organs and peripheral blood vessels) caused by atherosclerosis (AS) have become the leading cause of human death. At present, percutaneous transluminal angioplasty (PTA) and intravascular stenting have become the main methods for the treatment of vascular stenosis. Compared with traditional surgical treatment, interventional methods to open vascular stenosis have the advantages of less damage, higher technical success rate, shorter hospital stay, fewer complications, excellent curative effect, reusable application and no influence on other treatment methods, etc. application prospects. [0003] But in-stent restenosis (ISR) has become one of the main challenges it faces. Althoug...
