1. A method for flowing blood from an aneurysm bubble in a blood vessel back into the blood vessel, the method comprising:
utilizing an intravascular stent having an upstream proximal end, an opposite downstream distal end, a length between the proximal end and the distal end, and a longitudinal axis along the length, the stent having selected stent portions with leading edges directed toward the proximal end, trailing edges directed toward the distal end, outer surfaces, and inner surfaces, each of the outer surfaces of each of the selected stent portions having a first length between the leading edges and the trailing edges thereof, each of the inner surfaces of each of the selected stent portions having a second length between the leading edges and the trailing edges thereof;
inserting the stent into the blood vessel, with the selected stent portions positioned adjacent an opening into the aneurysm bubble;
diverting, by the leading edges of the selected stent portions, blood flowing through the blood vessel and the stent into first blood flow portions and second blood flow portions, the first blood flow portions flowing in first paths past the inner surfaces of the selected stent portions and the second blood flow portions flowing in second paths over the outer surfaces of the selected stent portions;
converging the first blood flow portions and the second blood flow portions adjacent the trailing edges of the selected stent portions;
wherein passage of the second blood flow portions over the outer surfaces entrains therein at least a portion of an amount of blood flow in the aneurysm bubble, and the converging first and second blood flow portions direct blood away from the aneurysm bubble and back into the blood vessel.
