Significant advances are being made in simulations for medical devices. The picture on the left, shared with me by Dr. Tina Morrison, former post-graduate student in Charles Taylor’s group at Stanford University shows the predicted pressures in a patient specific aorta. Flow and pressure waves emanate from the heart and travel through the major arteries where they are [...]
This is a picture of an excised mitral valve from a pig with suture and a clip holding the leaflets together in a novel approach to treating mitral valve regurgitation. It was placed percutaneously using a specially designed catheter. The superelastic Nitinol clip was designed and developed using Finite Element Analysis (FEA).

For the case of balloon expandable stents, this means modeling the crimping of the stent onto the delivery balloon, the expansion and recoil of the stent as would occur during deployment and finally the simulation of fatigue deformations. Fatigue deformations typically [...] |
