If you are interested in learning how to model a medical device interacting with physiology, then tune into this webinar featuring guest speaker Paul Belk from Abbott Medical.

Modeling physiologic systems uses the same principles applied to other multiphysics applications, but it is often complicated by the challenges in characterizing the properties of the biological tissues and processes involved. These challenges make it even more important to be able to analyze quantitatively through numerical simulation the interactions between the variable biological phenomena and the device.

In this webinar, we will present a model of catheter ablation from a large vessel. We will begin by setting up the coupled physics, including electric currents, laminar flow of blood, and heat transfer by conduction and convection. We will then show how to characterize the properties of the tissues involved and how the COMSOL Multiphysics® software can be used to simulate a closed-loop control system to stabilize the energy flow delivered to the surrounding tissues. The simulation results will be used to characterize how intended physiologic results can be affected by uncontrolled physiologic changes and which control systems are most robust.

You can ask questions at the end of the webinar during the Q&A session.
