Abstract

The invention discloses an interventional medial device comprising a balloon dilatation catheter body. A balloon on the balloon dilatation catheter body consists of a straightness section and conical sections positioned at two ends of the straightness section, wherein a medical coating is coated on the surface of the straightness section of the balloon and consists of medicaments and a medicine delivery promoting agent. When the balloon is used for dilating the narrow blood vessel, the medicament in the medical coating can be released rapidly, so that the injury of the endothelium of the blood vessel can be repaired, the hyperplasia of smooth muscle cells can be inhibited, the restenosis rate of the blood vessel can be reduced, and the endothelialization dysfunction possibly caused by the long-term continuous contact between the medical coating and the blood vessel wall can be avoided.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an interventional medical device. Background technique [0002] Since the 1970s, intraluminal balloon angioplasty has been widely used in the treatment of vascular stenosis caused by atherosclerosis. Although the immediate therapeutic effect of balloon angioplasty is satisfactory, the high incidence of surgical complications, especially restenosis, limits its wide application in clinic. [0003] Intravascular stenting is the implantation of a stent in the stenotic area while the balloon is inflated. The stent resists the restenosis caused by vascular delamination and elastic recoil, and can significantly reduce the acute or subacute ischemic complications of interventional therapy. However, the placement of stents stimulates the migration and proliferation of vascular smooth muscle cells, causing intimal hyperplasia and in-stent restenosis. And in recent years, the stent is coate...
