A staple delivery device includes a staple and an inserter. The inserter is movable between a free state and an actuated state, which moves the staple between a free state in which the staple legs converge and an elastically deformed state in which the staple legs are parallel. The inserter is connected to the staple by connections which can be ruptured after the staple has been implanted to cause the staple to move toward its free state, and to disconnect the inserter from the staple. Hybrid staples with polymer base members and metal reinforcing members are disclosed.
