A stent radially expandable from a radially contracted introduction state into a radially expanded position state, in which the final shape of the stent can be controlled by varying the amount and places energy is delivered onto the interior surfaces of the tubes from which the stent is fabricated, and means to seal the opening into the aneurysm, thereby causing the blood therein to clot and preventing the aneurysm from growing or rupturing. |
