Lecture Description

(April 6th) In this video lecture, Dr. Alan Pelton lectures on Stent Design and Nitinol Device Company (NDC).

Topics:
Nitinol, Austenite, martensite in 2D, lattice-invariant strain: twinning, shape memory effect, uses of nitinol, superelastic effect, stress-induced martensite, Beam Theory: strut angle, tip deflection, hoop stress, strut force, and moment. Nitinol stent cycle: crimp, RRF. Strut Length on COF. Pulsatile fatigue. Stenting diseased vessels.

Course Description

This course of UC Berkeley - Bio Engineering/ME C117: Structural Aspects of Biomaterials - provides an overview of medical devices, FDA regulatory issues, biocompatibility and sterilization technology. It examines biomechanical properties: isotropy/anisotropy, stiffness, bending stresses, contact stresses, multiaxial loading, plasticity, fatigue, fracture, wear, corrosion, design issues. Also covered: Orthopedics, Dental, Cardiovascular, and Soft Tissue Reconstruction.Professor Pruitt's current research is focused on fatigue and fracture micromechanisms, cyclic damage zones, and evolution of structure due to cyclic loading and environment in advanced polymers and biomaterials.
