1. A system for closing an opening in tissue, comprising:
- a closure element having;
a coiled body having a first free end and an opposing second free end, said body being formed of a resilient material, the first free end and the opposing second free end being disposed about an outer periphery, on opposite sides of the central axis of the coiled body in a closed configuration and separated by an angular separation of about 0 degrees in a pre-deployed, coiled expanded state; and
a plurality of tissue engaging portions disposed about at least a portion of said body between said first free end and said opposing second free end, said plurality of tissue engaging portions extending only from a first side of said coiled body in a first direction, said plurality of tissue engaging portions extending in the first direction in both the pre-deployed configuration and the closed configuration; and
a clip applier apparatus being configured to deploy said closure element into the tissue.

11. A system for closing an opening in tissue, comprising:
-
a closure element having; a coiled body having a central axis, a first free end, and an opposing second free end, said body being formed of a resilient material and having a first side, a second planar side opposite the first side, and a pair of planar sides extending from the second planar side toward the first side, the first free end and the opposing second free end being disposed about an outer periphery, on opposite sides of the central axis of the coiled body with a first angular separation of about 180 degrees in a closed configuration and separated by a second angular separation of about 0 degrees in a pre-deployed, coiled expanded state; and a plurality of tissue engaging portions disposed about at least a portion of said body between said first free end and said opposing second free end, said plurality of tissue engaging portions extending axially from only the first side of said coiled body in a first direction, said plurality of tissue engaging portions extending in the first direction in both the pre-deployed configuration and the closed configuration; and a clip applier apparatus being configured to deploy said closure element into the tissue, said clip applier apparatus including a locator assembly having a distal end region configured to extend into the opening and selectably contact a wall of the tissue and a proximal end configured to cooperate with a movable locator assembly block, a carrier assembly coupled with said locating assembly, said carrier assembly retaining said closure element within said carrier assembly, and a triggering system cooperating with said locator assembly, said triggering system moveable toward said distal end region of said locator assembly as said movable locator assembly block moves toward said distal end region. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
