Patent ID: 8182497

Claim:
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 at an angle through the plane, 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 toward another first curved region opposite the first curved region from which the at least one first primary tine extends, the at least one first primary tine being deflectable out of the plane when the body is moved towards the transverse configuration, wherein the at least one first primary tine overlaps the another first curved region which is opposite the first curved region from which the at least one primary tine extends; and at least one second primary tine extending from the another first curved region towards the first curved region opposite the another first curved region from which the at least one second primary tine extends, the at least one second primary tine being deflectable out of the plane when the body is moved towards the transverse configuration, wherein the at least one second primary tine overlaps the first curved region which is opposite the another first curved region from which the at least one second primary tine extends, wherein each of the first and second primary tines are offset from an axis of symmetry of the looped element from which the primary tine extends.
