Presentation Abstracts:

"Towards a Patient Specific Endovascular Treatment of Abdominal Aortic Aneurysms"
Endovascular repair (EVAR) of abdominal aortic aneurysms (AAAs) is becoming the standard treatment for AAA patients requiring vascular intervention. Current EVAR treatment options for AAA are limited as those with more complicated anatomies are not eligible for endovascular repair. Our research laboratory has developed a novel prototype for the endovascular treatment of patients with complex AAAs. In this presentation the prototype development history will be detailed and future work in this area will be discussed.

"Predictions of Drug Deposition in Arterial Tissue"
The use of medication for the treatment of cardiovascular disease has many manifestations. One of the most critical is the incorporation of medication into interventional treatments such as atherectomy, stenting, or angioplasty. The medication that is used is often able to inhibit restonsis of the clogged region and can increase long-term therapeutic benefit. This research presents a new way to model deposition of such medications into patient tissue.

"Improving Medical Device Design Robustness with Simulation and Six Sigma"
Numerical simulation has been widely used to design medical devices and also to assess performance, reliability and durability of the devices. Dassault Systemes SIMULIA corp. is dedicated to delivering leading analysis technologies to the medical industry. Finite element analysis (FEA) using Abaqus can be combined with statistical and probabilistic analysis using Isight to demonstrate how these techniques work together to evaluate the robustness of medical device designs. We demonstrate one such application using a case study from Medtronic pertaining to reliability study of a stent.
