Abstract

The invention discloses a drug-eluting-balloon catheter system with vibration. The system comprises a slender component and an expandable balloon, wherein the interior of the balloon is hollow and isprovided with a vibration structural unit; the surface of the exterior of the balloon is covered with a drug; when the balloon is fully expanded, the drug covering the surface is in contact with a vessel wall; the balloon enters a vibration state; the slender component is inside provided with a lumen; the lumen is communicated with the interior of the balloon, and is filled with gas or liquid; preferably, the drug-eluting-balloon catheter system also comprises a vibration source based on an ultrasonic or electrohydraulic effect; after the balloon is in a fully expanded state, the drug on the surface of the balloon is about to cling to the vessel wall; afterwards, the drug is promoted to be absorbed by the vibration. The drug-eluting-balloon catheter system can be used for enabling the drugon a drug eluting balloon to be better and more quickly absorbed by the vessel wall of a human body, and the treatment effect is improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a drug-eluting balloon catheter system with vibration. Background technique [0002] Cardiovascular stenosis is one of the main causes of coronary heart disease, and interventional therapy (Percutaneous Coronary Intervention, PCI) is an important means to treat cardiovascular stenosis. In addition, PCI can also be used to treat peripheral vascular diseases, such as carotid artery stenosis, Budd-Chiari syndrome, deep vein thrombosis, upper and lower extremity arterial stenosis, hemoptysis, and gastrointestinal bleeding. With the increase in the number of stents used, the problem of in-stent restenosis (ISR) is becoming more and more serious, and 5-60% of treated patients will have vascular restenosis in the short to medium term, which seriously limits the development of PCI. also, [0003] Intravascular interventional diagnosis and treatment, as a minimally invasive treatment, has...
