Outline of Final Research Achievements

In order to prevent the stent migration after a stent surgery for an abdominal aorta aneurysm, this study focused on three topics: 1) analysis of medical images, 2) experiments and analyses for artery and stent, and 3) development of simulation system for vascular surgery. In the topic 1, the system V-Modeler has been developed to investigate changes in vascular and stent geometry over a certain period time after the surgery. In the topic 2, the experimental system was designed to evaluate structural properties of the stent, and the comparison between experiment and analysis was performed. The simulations for contact problems between stent and artery were conducted under the physiological and mechanical conditions based on the results from the topic 2.
