This Best Practices document describes major aspects of stent modeling and simulation, familiarizing the reader with its core concepts and best practices. To take full advantage of this Best Practice, you must be familiar with the SIMULIA product Abaqus.
Stents are medical implants for human bodies and represent one of the most notable areas where bio-medical industry has advanced rapidly. This advancement has been possible in part due to the foray of simulation in this area which has largely complemented or replaced the traditional method of developing stents by prototyping and physical evaluation. Simulation through Finite Element Modeling (FEM) in a computer-simulated virtual environment has allowed the exploration of various stent designs and their failure modes in a very cost-effective and timely manner. Simulation has thus become an integral part in the design cycle of stents, helping the bio-medical industry to attain quicker turn-around times and a faster time to market.
The success of simulation in analyzing stents is demonstrated by the fact that simulation is a required procedure to get regulatory approval for commercialization of the device. Abaqus simulation is being used to predict stress-strain and fatigue response of stents in in-vivo conditions. In light of the importance of stents in the medical industry, it is imperative to tackle modeling of stents in some detail, which is the aim of this document.
The target audience for this document is the Users, Tech Support, Management, and Sales team.
