Diaphragm-pump FSI
Follow membrane deformation and fluid motion together to investigate pumping behavior. This diaphragm-pump example illustrates coupled mechanics beyond heart valves.
Beyond Heart Valves
Simulation capabilities for cardiovascular device development.
Investigate how a device interacts with fluid flow and anatomy. We combine structural mechanics, fluid dynamics and tailored software to compare designs, explain behavior and build simulation capability around your engineering questions.
Blood Pumps and Ventricular Assist Devices
Understand the flow.
Refine the design.
Investigate how pump geometry and operating conditions influence pressure generation, flow distribution, recirculation and shear exposure. Resolve local flow around the impeller, shaft and narrow passages to focus the next design comparison.
For LVAD and RVAD programs, the engineering question determines the model, operating points and quantities of interest.
Coupled Device Mechanics
Moving structures.
Coupled fluid response.
When fluid loading deforms a structure, and that deformation changes the flow, the two responses belong in the same evaluation.
Balloon Filling Simulation
Examine how filling, fluid loading and balloon deformation interact. A cutaway exposes the internal structure and computational discretization.
Whole-Heart Modeling
Device, tissue and blood flow in the whole-heart model.
The Living Heart Human Model brings anatomical structure, tissue mechanics and intracardiac flow into the same investigation. The tissue-valve example shows the device within the wider cardiac system.
Living Heart Human Model with tissue valves.
In collaboration with Dassault Systèmes.
Electromechanics and fluid flow across the cardiac cycle.
This full FSI model combines the electromechanical and fluid models of the Living Heart Human Model. The successive views reveal the evolving flow field as the heart moves through the cycle.
Anatomy and Blood Interaction
Look beyond pressure and flow rate.
Examine local flow structures, shear exposure, residence time and washout to investigate mechanisms that integral measurements cannot describe on their own.
Model-based indicators of blood damage and thrombogenicity can support design comparisons and help focus further testing. The selected atrial example illustrates flow visualization within a beating anatomical model.
Tailored Technology
Software and workflows built around your questions.
Develop tailored simulation software, automate repeated workflows and improve or extend models for your device program. The scope can include sizing tools, repeatable evaluation pipelines, custom calculations and reporting.
Begin with a focused study, integrate FSI into an existing engineering team or build a broader capability with our specialists.
