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 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. The primary tines are configured such that they are offset from the axes of symmetry of the curved regions from which they extend and are connected to the curved regions by curved or linear regions or are connected directly to the curved regions. The primary tines may overlap the body and may be of different lengths.

What is claimed is: 1. A device for engaging tissue, comprising: a generally annular-shaped body defining a plane and disposed about a central axis extending substantially normal to the plane, the body being movable from a substantially planar configuration lying generally in the plane towards a transverse configuration extending out of the plane, the body being biased to return toward the planar configuration from the transverse configuration, the body comprising a plurality of looped elements comprising alternating first and second curved regions; at least one first primary tine extending from a first curved region of a looped element of the annular-shaped body generally towards the central axis in the planar configuration and being deflectable out of the plane when the body is moved towards the transverse configuration; at least one second primary tine extending from another first curved region of a looped element of the annular-shaped body towards the first primary tine when the body is disposed in the planar configuration; and said first and second primary tines being offset from and substantially parallel to an axis of symmetry of the looped element from which they extend, said first and second primary tines being substantially parallel to each other. 2. The device of claim 1, wherein the body is biased towards the planar configuration for biasing the primary tines generally towards the central axis. 3. The device of claim 1, further comprising: a set of secondary tines having lengths shorter than a first length of the at least one first primary tine and a second length of the at least one second primary tine, the secondary tines extending from the annular-shaped body generally towards the central axis in the planar configuration and being deflectable out of the plane when the body is moved towards the transverse configuration. 4. The device of claim 1, wherein the at least one first primary tine, the at least one second primary tine, and the body are formed from a single sheet of material. 5. The device of claim 4, wherein the sheet of material comprises a superelastic alloy. 6. The device of claim 1, wherein the looped elements generally define an endless zigzag pattern extending about the central axis. 7. The device of claim 6 wherein the endless zigzag pattern comprises a generally sinusoidal pattern. 8.

The device of claim 11, wherein the plurality of looped elements are biased towards the compressed state. 13. The device of claim 1 wherein said first and second primary tines are connected to said first curved regions of said looped elements by a connector element. 14. The device of claim 13 wherein said connector element is curved. 15. The device of claim 13 wherein said connector element is straight. 16.
