Description

technical field

[0001] The application relates to a drug balloon catheter with a blocking function. Background technique

[0002] In recent years, with the rapid development of neuroimaging, catheter technology, materials, and computers, endovascular interventional technology has become increasingly mature in the treatment of vascular diseases, and has been affirmed by doctors and patients for its minimally invasive, safe, and effective features. At present, it has become one of the important treatment methods for vascular diseases.

[0003] In the interventional treatment method, a balloon catheter is needed. The balloon catheter is a tool for angioplasty. The balloon is sent into the atherosclerosis and stenosis through the guide wire and the guiding catheter, and the balloon is expanded with pressure. It is a very effective new technology in the treatment of cardiovascular diseases in recent years, which can crack plaque, expand blood vessels, and improve blood flow. Ho...
