A device for engaging tissue may include a generally annular-shaped body defining a plane and disposed about a central axis extending substantially normal to the plane. The body may be movable from a substantially planar configuration lying generally in the plane towards a transverse configuration extending out of the plane. The body may include a plurality of looped elements including alternating inner and outer curved regions. The inner curved regions may define an inner periphery of the body and the outer curved regions may define an outer periphery of the body in the planar configuration. A plurality of tines may extend from the outer curved regions. The tines may be oriented generally towards the central axis in the planar configuration and generally parallel to the central axis in the transverse configuration. The tines may extend beyond the central axis without passing through the central axis so as to collectively form a central lumen about the central axis in the planar configuration.
