Finite element analysis of Nitinol stent (application in thoracic aorta) / Ahmad Faizul Fahmi Mohd
Stent is a wire mesh tube placed in an artery to support and prevent artery from reclosing. Stent commonly made from Nitinol is well known for its shape memory property. It is widely used in medical application. However, there are several problems related to stent implantation. One of the most commo...

Stent is a wire mesh tube placed in an artery to support and prevent artery from reclosing. Stent commonly made from Nitinol is well known for its shape memory property.

The main objective of this project was to propose a new stent design to overcome this problem. This project involved analysis of three different stent design; the generic models and the proposed new design using Finite Element Method (FEM).
