ABSTRACT
The surface-coated vascular stent of shape memory alloy was made for use of occlusion of pseudo-lumen of the dissecting aneurysm of the aorta, as the usage of shape memory alloy in angioplasty, and the metal flexible delivery catheter was also made for the introduction of the stent. In the present study, antithrombogenicity of the vascular stent was much improved by surface-coating with EPTFE and segmented polyurethane. The long-term usage of the stent was confirmed by radiological, macroscopic, and electron microscopic examinations. Moreover, the metal flexible delivery catheter was demonstrated to be of much benefit for the introduction of the surface-coated vascular stent of shape memory alloy.
