Claim:
1. An intra-vascular aneurysm-treatment stent comprising: 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, and a length between the proximal end and the distal end, 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 arcuate surface and an inner substantially planar surface extending from proximate the leading edges to proximate the trailing edges; 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 arcuate surfaces and second portions of the blood flow across the inner substantially planar 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.
