Claim Text:
1. A method of reducing an amount of blood flow within an aneurysm bubble in a blood vessel, the method comprising: utilizing a flexible intravascular stent coil having an upstream proximal end, an opposite downstream distal end, and a length between the proximal end and the distal end, the coil having selected portions with leading edges directed toward the proximal end, trailing edges directed toward the distal end, and outer arcuate surfaces and inner substantially planar surfaces extending from proximate the leading edges to proximate the trailing edges; inserting the stent coil into the blood vessel, with the selected stent coil portions positioned proximate an opening into the aneurysm bubble; and flowing blood through the blood vessel and the stent coil, with first blood flow portions flowing in first paths past the inner substantially planar surfaces of the selected stent coil portions, and second blood flow portions diverted by the leading edges to flow in second paths over the outer arcuate surfaces and past the trailing edges, the flow of the second blood flow portions over the outer arcuate surfaces entraining therein at least a portion of the amount of blood flow within the aneurysm bubble, the second blood flow portions converging with the first blood flow portions at the 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, thereby reducing the amount of blood flow within the aneurysm bubble.
