||Cardiovascular diseases have been the primary threats of human health and life all the time, the traditional treatments of cardiovascular diseases are medicinal treatment and operation. But the traditional operation is full of high risk and hard to operate. Moreover, it also takes lots of money. Therefore, a new medical technology - Coronary Stent, is developing and paid more and more attention by people. It’s a new treatment with advantages such as low invasion, light wound, high safety, and reduces the possible complications of main organs.|
In this research, we build the stent models - MAC Stent, Maneo Stent, Palmaz Stent, which construct three kinds of different high complicated curved surfaces by SolidWorks, and execute finite element analysis. We analyze the stress distribution of blood vessel and stent got through contraction and dilation, to understand the influence on the wall of blood vessel when stent planted into blood vessel and brace the wall. In addition, set different materials including 316L stainless steel, Ti-6Al-4V and N-Ti alloy for each model, and probe into the stress value and distribution of these models.
