摘要:An intra-vascular aneurysm-treatment stent and a method for loweringpressure within an aneurysm bubble in a blood vessel. A stent coil is insertable into ablood vessel, the coil made of a material sufficiently flexible to move around curves,
loops, and corners in the blood vessel. Selected portions of the stent coil, in cross-section, have substantially convex outer surfaces, and either substantially flat, orsubstantially concave, inner surfaces, plus upstream leading edges and downstreamtrailing edges. The stent coil is positioned in the blood vessel with selected stent coilportions proximate an opening into either a saccular aneurysm or a fusiform aneurysm.Blood in the lumen of the blood vessel flows past the leading edges and both over theconvex outer surfaces, and under the either flat or concave inner surfaces. A portion ofthe blood inside the aneurysm becomes entrained with the blood flowing over the outersurfaces. At the trailing edges, the converging blood flows create eddies which result indPs proximate the opening into the aneurysm. The dPs draw more blood out of theaneurysm and into the lumen, reducing pressure in the aneurysm.
