A clip for engaging tissue includes a generally annular-shaped body defining a plane and disposed about a central axis extending normal to the plane. The body includes alternating inner and outer curved regions, defining a zigzag pattern about a periphery of the clip. The body is biased towards a planar configuration lying in the plane and deflectable towards a transverse configuration extending out of the plane. Tines extend from the inner curved regions, the tines being oriented towards the central axis in the planar configuration, and parallel to the central axis in the transverse configuration. The tines may include primary tines and secondary tines that are shorter than the primary tines. The primary tines may be disposed on opposing inner curved regions and oriented towards one another such that they overlap in the planar configuration.

1. A device for engaging tissue, comprising: a generally annular-shaped body defining a generally central opening and a plane, the body having a plurality of outer curved regions, the body movable from a planar configuration with the body lying substantially in the plane to a transverse configuration having at least a portion of the body extending out of the plane;a plurality of tines extending from the body into the central opening, a portion of pairs of adjacent outer curved regions of the plurality of outer curved regions extending towards the central opening to terminate at each tine of the plurality of tines; andat least one spring element extending between pairs of adjacent tines of the plurality of tines, each at least one spring element aiding in expanding the body as the body moves from the planar configuration to the transverse configuration, wherein each of the at least one spring element has a curved inner region that curves towards the central axis. 2. The device of claim 1, wherein at least a portion of the the curved inner region extends toward the generally central opening a distance lesser than at least one tine of the plurality of tines to limit the depth of penetration of the at least one tine of the plurality of tines into tissue. 3. The device of claim 1, wherein the plurality of tines move radially as the body moves from the planar configuration to the transverse configuration. 4. The device of claim 1, wherein the at least one spring element comprises a hollow diamond-shape. 5. The device of claim 1, wherein each tine of the plurality of tines further comprises at least one tip, the at least one tip being in the plane when the body is in the planar configuration. 6. A device for engaging tissue, comprising: a generally annular-shaped body disposed about a central opening and a central axis normal to the plane, the body having a plurality of outer curved regions with adjacent outer curved regions of the plurality of outer curved regions being joined together to define an outer periphery of the body, the body defining a plane and being movable from a planar configuration with the body lying substantially in the plane to a transverse configuration having at least a portion of the body extending out of the plane;a plurality of tines extending from the body into the central opening, each tine of the plurality of tines extending from a junction of a pair of adjacent outer curved regions of the plurality of outer curved regions that extend toward the central opening; andat least one spring element extending between pairs of adjacent tines of the plurality of tines, each of the at least one spring elements having a spring curved inner region that curves towards the central axis and a spring curved outer region that curves towards an apex of one of the plurality of outer curved regions, the at least one spring element aiding in drawing the tissue towards the central axis of the body when the body moves from the transverse configuration towards the planar configuration. 7.
