Abstract:
An intra-vascular aneurysm-treatment stent and a method for lowering pressure within an aneurysm bubble in a blood vessel. A stent coil is insertable into a blood vessel, the coil made of a material sufficiently flexible to move around curves, loops, and corners in the blood vessel. The stent coil is positioned in the blood vessel with selected stent coil portions 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 the outer surfaces, and under the inner surfaces. A portion of the blood inside the aneurysm becomes entrained with the blood flowing over the outer surfaces. At the trailing edges, the converging blood flows create eddies.

Claim (Index 14):
An intra-vascular aneurysm-treatment stent comprising:\n a flexible coil, insertable into a blood vessel, with selected portions of the coil positioned proximate an opening in a wall of the blood vessel, and opening into an aneurysm bubble, the coil having an upstream proximal end, an opposite downstream distal end, a length between the proximal end and the distal end, and a longitudinal axis extending along the length, the selected portions of the coil each having a leading edge directed toward the proximal end, a trailing edge directed toward the distal end, and an outer surface and an inner surface extending from proximate the leading edges to proximate the trailing edges, at least one of the selected portions having a first cross-section in a first plane parallel to the longitudinal axis, the outer surface in the first cross-section having a first end and an opposite second end, and the inner surface in the first cross-section having a third end and an opposite fourth end, the first, second, third, and fourth ends terminating at a second plane perpendicular to the first plane and parallel to the longitudinal axis, the inner surface being located at or above the second plane, a third plane perpendicular to the first plane and the second plane, the third plane intersecting the first cross-section between the leading edge and the trailing edge in the first cross-section, and the third plane intersecting the second plane, a fourth plane perpendicular to the first plane and the second plane, the fourth plane intersecting the first cross-section between the leading end and the intersection of the third plane with the first cross-section, a fifth plane perpendicular to the first plane and the second plane, the fifth plane intersecting the first cross-section between the trailing end and the intersection of the third plane with the first cross-section, a distance between the outer surface and the second plane in the first cross-section at the intersection of the third plane being greater than a distance between the outer surface and the second plane in the first cross-section at each of the intersections of the fourth and fifth planes, a distance between the inner surface and the second plane in the first cross-section at the intersection of the third plane being greater than a distance between the inner surface and the second plane in the first cross-section at each of the intersections of the fourth and fifth planes, the flexible member having a maximum distance between the outer surface and the second plane in the third plane; wherein the selected portions of the coil are configured to receive blood flow at respective upstream leading edges, direct first portions of the blood flow over the outer surfaces and second portions of the blood flow across the inner surfaces, the first blood flow portions converging with the second blood flow portions at respective trailing edges, the converging first and second blood flow portions at least temporarily directing blood away from the aneurysm bubble and back into the blood vessel.
