1. A vascular occlusion device to occlude a treatment site comprising:
an outer tube;
an inner tube positioned within and extending beyond the outer tube;
a vascular plug attached distally to the inner tube and proximally to the outer tube, the vascular plug comprising an inner layer and an outer layer, wherein the inner layer comprises a mesh, and wherein the outer layer comprises a plurality of struts;
a hemostatic valve connected to the outer tube; and
a fitting connected adjacent to the hemostatic valve, the fitting being adjustable between a first configuration in which the fitting locks the inner tube relative to the outer tube to thereby fix a radial shape of the vascular plug and a second configuration in which the fitting does not lock the inner tube relative to the outer tube; an introducer located at and in fluid communication with a proximal end of the inner tube; and,
where the inner tube can be pushed or pulled independently of the outer tube to control a radial shape of the vascular plug.
