Analytical Models for Predicting Mechanical Properties of Self- Expandable Metal Stents with Cover Membrane.

摘要

Various mechanical characteristics of 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. Then, these models were verified with the test results derived from some prototype and commercially available stents. The models allow for the characterization of mechanical properties of stents and may be instrumental in developing clinically efficacious stents.
