Problems solved by technology
[0006] The technical purpose of the present invention is to provide a drug balloon catheter that can maintain the blood supply at the distal end, so as to solve the problem that the existing interventional drug-coated balloon catheter works in blood vessels due to blocked blood flow, which makes the treatment effect ineffective. good question

Abstract
The invention discloses a drug balloon catheter capable of maintaining far-end blood supply. The balloon catheter comprises a tip tube, a balloon, an inner tube and an outer tube. A near end of the balloon is fixedly connected to an outer tube, and a far end of the balloon is fixedly connected to the tip tube. The inner tube extends out of the outer tube and penetrates through a hollow cavity of the balloon, and the far end of the inner tube extends out of the balloon and is connected with the tip tube. A blood flow anti-blocking mechanism is included and is used for forming a blood flow passage which passes through a section where the balloon is located and is connected with a blood vessel in the drug balloon catheter. During interventional therapy, the blood vessel cannot be blocked, far-end blood supply is kept through a blood flow path, far-end ischemia is avoided, and therefore interventional therapy time is longer, medicine release is sufficient, and the blood vessel is not easyto carry out springback and contraction after interventional therapy is completed.
Description
technical field [0001] The invention relates to the technical field of angioplasty, in particular to a drug balloon catheter capable of maintaining distal blood supply. Background technique [0002] Balloon angioplasty is one of the most commonly used treatments for vascular disease. Traditional balloon angioplasty is often accompanied by damage to blood vessels. For example, the diameter of the proximal and distal ends of the balloon is greater than the diameter of the middle of the balloon during balloon expansion, that is, the "dog bone effect", resulting in blood vessels in contact with both ends of the balloon Excessive expansion can cause damage to the vessel wall and lead to the longitudinal elongation of the balloon to accelerate vessel dissection (>30%), and can also cause acute vessel occlusion (5%-12%) and postoperative restenosis (50%) at the lesion site. Vascular dissection, acute vascular occlusion, and vessel wall injury are all vascular trauma caused by t...
