A clip applier (10) is adapted for use in positioning, and actuating a surgical clip (78) relative to body tissue. The applier includes a pair of handles (47, 50) operable by a user, and a cartridge (23) containing a plurality of clips removably attached to the handles. A pair of jaws (74, 76 ) are carried by the cartridge, adapted to receive, and actuate the clips by operation of the handles. An anti-scissoring mechanism (94) maintains the alignment of the jaws. Within the cartridge ultimate (112), the penultimate (114) clips are moved along a clip path by an active pusher (98), and a passive gate structure (147). As the pusher moves the ultimate clip to its operative position, a spacer (141) of variable length moves the penultimate clip into the gate structure.
