Thermoelastic Transformation Behavior of Nitinol
The transformation behavior of Nitinol under uniaxial tension and four-point bending was investigated. A novel sample geometry produced from drawn tubing was used to [...]
ASTM Stent Radial Force Characterization
You can download a report where Dr. Paul and I explored modeling the radial force characteristics of stents andd the various details associated [...]
Phase Transformations in Nitinol
Nitinol is well suited to the design constraints imposed by medical device applications, however, only modest progress has so far been made regarding long [...]
LifeStent NT Self-Expanding Helical Stent
The 6F LifeStent NT is an implantable self-expanding nickel titanium alloy (Nitinol) stent. The stent is manufactured from small diameter Nitinol tubing and is [...]
Effects of Notches and Grain Size on Transformations in Nitinol
In this paper, we present a research methodology to characterize the effects of crystallographic orientation and grain size on the deformations and transformations in [...]
FEA and Experimental Evaluation of Superelastic Stent
The mechanical properties of Nitinol stents are normally evaluated experimentally due to complexities resulting from large deformations and material nonlinearity. Despite difficulties associated with [...]
