Patent ID: 8876886

Claim:
A method of implanting a braided stent into a blood vessel having an aneurysm area, comprising: a): introducing a one-piece braided stent in a stretched state to a site of implantation having an aneurysm, wherein the one-piece braided stent in the stretched state is stretched along a longitudinal direction of the one-piece braided stent; and b): deploying the one-piece braided stent into an expanded state so that a proximal portion and a distal portion of the one-piece braided stent lie proximally and distally, respectively, from the aneurysm, and a central portion of the one-piece braided stent lies, at least partially, adjacent a stenosis of the aneurysm area, wherein the one-piece braided stent has multiple filaments that, in the expanded state, intersect a plane perpendicular to the longitudinal direction at a braiding angle, wherein the braiding angle is relative to a transverse direction of the stent, the braiding angle of the one-piece braided stent being smaller in the central portion than in the proximal and distal portion, wherein the smaller angle of the braided stent in the central portion forms a dense mesh network of the filaments, wherein the dense mesh network prevents transport of plaque from the aneurysm area, wherein the diameter of the stent in the central portion is approximately equal to or less than a dilated internal diameter of the stenosis when the stent is in an unrestrained state, and wherein a length of the central portion of the stent in the stretched state is 500-600% greater than a length of the central portion in the expanded state.
