First Claim
1. A device for engaging tissue, comprising:
- a generally annular-shaped body defining a generally central opening and a plane, 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; and
at least one spring element extending between adjacent tines of the plurality of tines, each at least one spring element aids in expanding the body as the body moves from the planar configuration to the transverse configuration.

Abstract
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.
