Abstract
Mechanical characteristics of several mesh-type stents were analyzed and mathematical models were developed in order to predict expansive pressure of stents. Given the geometry and material properties of a stent, one can utilize these models to predict its expansive pressure properties. These models were subsequently verified with the test results derived from several available stents. The models allow characterization of mechanical properties of stents and may be instrumental in developing clinically efficacious stents.
