Medical Implant Material Fatigue Research
With the growing use of Nitinol in medical implants, there is a need for improved characterization of the material behavior of Nitinol and methodologies [...]
Recent Moire Interferometry Experiments
We dusted off the interferometer recently to perform some new experiments on Nitinol. The photo on the left shows our four beam phase shifted [...]
Medical Imaging Data and Computational Fluid Dynamics
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 [...]
Suture Clip for Percutaneous Mitral Valve Repair
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 [...]
Computing Alternating and Mean Stresses During Fatigue for a Cardiovascular Stent
Finite Element Analysis (FEA) is routinely used to perform fatigue analyses of cardiovascular stents. For the case of balloon expandable stents, this means modeling [...]
