The treatment works by promoting blood clotting (thrombosis) in the aneurysm, eventually sealing it from the blood flow. This is accomplished by decreasing the amount of blood flow going into the aneurysm, increasing the residence time of the blood (thereby lowering the velocity) in the aneurysm space and reducing the wall shear stress of the aneurysm wall. This change in the blood flow, or hemodynamics, is ultimately dependent on several factors, including: * aneurysm type (directly on the parent artery or on a bifurcation of an artery) * aneurysm position (relative angle of aneurysm to approaching blood flow) * coil packing density * angle of parent vessel curvature * size of aneurysm neck While these factors are crucial to the success of the procedure, thrombosis ultimately is dependent on biological processes, with the<unk>  only providing the appropriate conditions for the process to occur, and hopefully closing the aneurysm.
