Artificial Heart Valves |
|
In order
to design and test the performance of artificial heart valves it is
imperative to have knowledge of the dynamic blood flow field within
the valve. However, detailed information on the microscopic flow
structures within the valve (especially in the socket area) is
experimentally inaccessible. CFD simulations provide insight
into the microscopic flow structures. |

Aneurysms |
|
An aneurysm is
a localized and abnormal dilation of an artery due to weakening of the
vessel wall. A CFD simulation of blood flow within an aneurysm provides
valuable information that is helpful for understanding the growth pattern
and danger of rupture. |

Arterial Blood Flow |
|
Analysis of
blood flow in vessels can give an insight into stenosis, aneurysms, and
other pathological conditions. A CFD simulation of arterial blood flow
reproduces clinical observations and provides additional flow details.

Cardioplegia Device |
|
CFD was
utilized in the development and optimization of a blood cardioplegia device,
predicting heat transfer and flow characteristics before prototypes are
fabricated. Based on numerical simulations, water and blood flow paths in
the heat exchanger are optimized to yield superior heat transfer performance
with a minimal energy exchange surface. Experimental measurements have
confirmed the validity of the results from the CFD analysis. CFD analysis
performed for Sorin Biomedical. |

Catheters |
|
CFD provides a
non-invasive tool to assess catheter placement in the central venous system.
Numerical simulations of blood flow around the catheter can be used to
predict pressure and viscous forces acting on the device. This type of
information is critical to evaluate catheter displacements inside the vein
and possible damage to the vessel wall. CFD techniques produce
fluid-structure interaction data usually not available directly from in vivo
or in vitro measurements. |

Heart Pumps |
|
CFD can be used to model many types of heart pumps, such as diaphragm driven
pumps or propeller driven pumps. |
