Background art:
at present, coronary heart disease and cardiovascular and cerebrovascular diseases become one of the important diseases endangering the health of the public, especially the middle-aged and the elderly, for example, the main cause of coronary heart disease is caused by coronary artery stenosis or occlusion caused by coronary atherosclerosis so as to reduce or interrupt coronary artery blood flow, and in medicine, the most important method for treating vascular diseases caused by the stenosis or occlusion is coronary artery interventional therapy, namely percutaneous coronary artery saccule expansion and stent implantation. The basic principle of balloon dilation is to dilate a stenosed vessel by mechanical force (the balloon presses against the stenosed site). For some simple vascular diseases, only balloon dilatation may be needed, but the simple balloon dilatation often causes restenosis of the blood vessel, so in recent years, stent treatment is often performed after the balloon dilatation. The function of the stent is to maintain the enlarged blood vessel lumen.
However, the existing coronary stent may have an elastic retraction phenomenon after being used for a period of time, and then needs a patient to perform secondary treatment, which is very troublesome.
