1. An occlusion device configured to shift between an expanded configuration sized to occlude a body passage or lumen and an unexpanded configuration sized for delivery to or removal from the body passage or lumen, said occlusion device comprising:
a proximal plug section;
a distal plug section;
an intermediate section extending between said proximal plug section and said distal plug section; and
a center core having a proximal end configured to mate with a distal end of a deployment device, and a distal end, said center core extending from said proximal end adjacent said proximal plug section, through said proximal plug section and through said distal plug section to the distal end adjacent said distal plug section in the unexpanded configuration of said occlusion device;
wherein:
said proximal plug section and said distal plug section present a smooth atraumatic outer surface for engagement with the body passage or lumen; and
said center core is longitudinally movable through said proximal plug section and said distal plug section to shift said occlusion device between the expanded and unexpanded configurations.
