Abstract:
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.
