Cataloged from PDF version of thesis.
Includes bibliographical references (page 30).
This thesis describes a method for setting up, testing and analyzing cardiovascular stents in multiple deformation modes. Testing stents in multiple deformation modes, including bending, torsion and compression simultaneously is a novel technique. Specific details are provided on strategies for inserting a stent sample into the testing apparatus such that stent integrity is preserved. Using a dynamic feedback cycle for buffered video capture we have been able to document sequential fracture events during testing scenarios. Stereomicroscopy further allows us to detect and determine placement of stent fracture. This method will help stent designers to create stents that are more likely to stand up to the particular conditions they will face in the body and regulatory agencies to determine how well potential new stents will fair under physiologic conditions.
