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.
What is claimed is: 1. A method for manufacturing a clip configured for closing an opening in a body lumen, comprising:providing a sheet of material defining a plane;removing one or more portions from the sheet to form a clip comprising a generally-annular body including a plurality of looped elemen
What is claimed is: 1. A method for manufacturing a clip configured for closing an opening in a body lumen, comprising:providing a sheet of material defining a plane;removing one or more portions from the sheet to form a clip comprising a generally-annular body including a plurality of looped elements defining a periphery, and a plurality of tines extending from the body within the plane;heat treating the clip with the clip in a planar configuration such that the clip is capable of resuming the planar configuration upon release from a deformed state and the plurality of tines extending within the plane of the clip to program the plurality of looped elements of the clip and the plurality of tines to be biased to remain within the plane in the planar configuration; anddeforming the clip to a transverse configuration in preparation for loading on a delivery apparatus, wherein the tines extend out of the plane.
