| Popis: | The goal of this work is the mechanical comparison of different types of stents for colorectal obstructions. We consider self-expanding and balloon-expanding stents made of two different materials such as stainless steel and shape memory NiTi alloy. The mechanical parameters are expansion rate, shortening, radial compression resistance, longitudinal and perimetral adaptability, and buckling resistance. This analysis results in a better understanding of global mechanical behavior and also allows better design and device selection for colonic lesions. |
