Your Turn! Interactive Online Experience: Stent

Welcome to our new series, “Your Turn!,” where you can try out different simulation experiences. This experience uses Finite Element Modeling to explore various stent designs in the biomedical industry. Don’t forget to try out the experience for yourself!

Stents and grafts used as implants represent one of the most notable areas where biomedical industry has advanced rapidly. This advancement has been possible in part due to 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.

Now as a next natural step to application of simulation in this area, we intend to further complement In-Vivo and In-Vitro testing of these devices with In-Silico virtual models. In this demo example, along with the stent model, the artery is also created to mimic the human artery blocked with plaque deposition . Stent is deployed in this “Virtual Human Model ” artery (VHM) and pulsatile loading representing flow of the blood is applied under systolic and diastolic cycles. Fatigue life of the stent is then derived under this pulsatile loading in VHM artery which represents closest realistic operating condition for a stent. In future, using the parametric modelling for the artery, this demo will also be enhanced for allowing the device manufactures for virtual patient population studies to build greater confidence on the devices produced.
