Abstract
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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
125 words
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 comprising a plurality of looped elements comprising alternating first and second curved regions, the first curved regions defining an inner periphery of the body and the second curved regions defining an outer periphery of the body in the planar configuration; and a plurality of tines extending from the first curved regions, the tines being oriented generally towards the central axis in the planar configuration, and generally parallel to the central axis in the transverse configuration.
Claim 2
Independent Claim
125 words
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 comprising a plurality of looped elements comprising alternating first and second curved regions, the first curved regions defining an inner periphery of the body and the second curved regions defining an outer periphery of the body in the planar configuration; and a plurality of tines extending from the first curved regions, the tines being oriented generally towards the central axis in the planar configuration, and generally parallel to the central axis in the transverse configuration.
Claim 3
Dependent Claim
24 words
The device of claim 1 , wherein the body is biased towards the planar configuration for biasing the tines generally towards the central axis.
Claim 4
Dependent Claim
21 words
The device of claim 1 , wherein the looped elements generally define an endless zigzag pattern extending about the central axis.
Claim 5
Dependent Claim
16 words
The device of claim 3 , wherein the endless zigzag pattern comprises a generally sinusoidal pattern.
Claim 6
Dependent Claim
17 words
The device of claim 1 , wherein adjacent tines have a first curved region disposed between them.
Claim 7
Dependent Claim
30 words
The device of claim 5 , wherein at least one of the tines comprises a stop member disposed between a tip of the tine and the respective first curved region.
Claim 8
Dependent Claim
21 words
The device of claim 6 , wherein the stop member comprises a blunt base that is substantially wider than the tine.
Claim 9
Dependent Claim
33 words
The device of claim 1 , wherein the plurality of looped elements are movable between expanded and compressed states for increasing and reducing, respectively, a periphery of the body in the transverse orientation.
Claim 10
Dependent Claim
18 words
The device of claim 8 , wherein the plurality of looped elements are biased towards the compressed state.
