Cardiovascular

Implantable cardiovascular devices — stents, coils, heart valves and pacemakers — are complex as a result of exacting product and regulatory (FDA) specifications. The study of hemodynamics is critical to cardiac device engineering, which can benefit greatly from engineering simulation and advanced fluid–structure interaction modeling.

Inserting devices via minimally invasive treatment calls for unwavering accuracy, such as when threading devices through veins or arteries. Replacement surgery is risky, and product failure can have catastrophic consequences — to patients as well as an organization in terms of reputation and warranty costs.

Reliable computer modeling helps researchers to confidently investigate all facets as they shorten product development time. Robust design methodology is invaluable in inventing and improving implantable materials that co-exist (without complications) with organs, tissues and blood.

ANSYS simulation software uniquely integrates fluid, structural, thermal and (when needed) electromagnetics analyses into a single environment, providing insight into how cardiovascular devices behave within the human body. Such analyses are crucial to preventing or reducing related side effects.
