Problems solved by technology

However, the current drug-coated balloon catheter has insufficient binding force between the therapeutic drug and the balloon catheter, which leads to the drug coating being washed by the high-speed flowing blood during the delivery of the drug-coated balloon catheter in the blood vessel. The drug is easy to fall off from the balloon catheter, thereby reducing the amount of drug that the drug-coated balloon catheter can release in the lesion, and affecting the use effect of the drug-coated balloon catheter

Embodiment Construction

[0022] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] Drug-coated balloon catheters are usually loaded with a drug coating on the outer wall of the balloon body. After the drug-coated balloon body is delivered to the lesion, the balloon body expands, making the blood vessels in the lesion unobstructed, and at the same time The drug coating on the outer wall of the balloon body is released from the balloon body to the blood vessel wall, so as to further inhibit the proliferation of smooth muscle cells through the action of the drug, and prevent restenosis of blood vessels.

[0024] During the delivery of the drug-coated balloon catheter, the outer wall of the drug-coated balloon body will be washed by the flowing blood, which will not only cause the drug to fall off, increase the loss ra...

Abstract

The invention provides a drug-coated balloon catheter, and relates to the technical field of medical instruments. The rug-coated balloon catheter comprises a balloon main body, a catheter and a low-temperature plasma jet device, and a drug coating is loaded on the outer wall of the balloon main body; the tail part of the balloon main body is connected to the front end of the catheter; the low-temperature plasma jet device generates low-temperature plasma jet through electric discharging, and jets the low-temperature plasma jet to the outer wall of the balloon main body. The invention providesthe drug-coated balloon catheter. The low-temperature plasma jet device generates the low-temperature plasma jet through electric discharging, and jets the low-temperature plasma jet to the outer wallof the balloon main body; on the one hand, the amount of medicine released at the lesion position is increased, and the treatment effect is improved; and on the other hand, residues of the medicine in blood vessels can be reduced, blockage at the far ends of the blood vessels is avoided, metabolic burdens of organisms are reduced, and then the use safety of the drug-coated balloon catheter is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a drug-coated balloon catheter. Background technique [0002] In recent years, drug coated balloon (DCB), as a new interventional therapy technology, has been widely used in the field of coronary artery and peripheral intervention in Europe, and several DCB products have been or will be put into clinical use in China. However, the current drug-coated balloon catheter has insufficient binding force between the therapeutic drug and the balloon catheter, which leads to the drug coating being washed by the high-speed flowing blood during the delivery of the drug-coated balloon catheter in the blood vessel. The drug is easy to fall off from the balloon catheter, thereby reducing the amount of drug that the drug-coated balloon catheter can release in the lesion, and affecting the use effect of the drug-coated balloon catheter. Contents of the invention [0003] The problem s...
