A Finite Difference Numerical Analysis of Heat Transfer in Atheromatous Plaque for Percutaneous Transluminal Microwave Angioplasty
Abstract
Various percutaneous transluminal angioplasty methods have been under development for the treatment of athersclerosis. The microwave angioplasty method is a new technique that has a tremendous potential for selectively heating atheromatous plaques in arteries with minimal thermal damage. The purpose of this study is to evaluate the heat transfer within the vascular system while being exposed to a high energy electromagnetic field induced by a microwave applicator. A heat tranfer analysis was accomplished using the explicit finite difference method. The angioplasty system was modelled as a two-dimensional cylindrical coordinate thermal system to solve for the conductive heat transfer in the atheromatous plaque, vascular tissue, and muscle.
