Tacking device and methods of deployment

A method suitable for coupling a graft member to tissue, the method comprising:

• positioning the graft member over a selected region of the tissue;
• providing at least one tacking device comprising a wire having delivery and deployed states;
• delivering the tacking device within a hollow lumen of an insertion tool, wherein the wire is provided in the delivery state having an elongated configuration that is substantially parallel to a central longitudinal axis;
• and
• moving the insertion tool and the tacking device relative to one another to cause the wire to be ejected from the insertion tool and deploy to the deployed state,
• wherein, in the deployed state, the wire comprises a head region comprising at least one full turn that abuts the graft member, and the wire further comprises a body region comprising at least two full turns that engage the tissue.

A tacking device comprising:

• a wire having first and second ends, and further having delivery and deployed states,
• wherein, in the delivery state, the wire comprises an elongated configuration that is substantially parallel to a central longitudinal axis, and
• wherein, in the deployed state, the wire comprises a head region, a body region and a junction disposed therebetween, the head region comprising at least one full turn and the body region comprising at least two full turns,
• wherein the junction changes a direction of curvature of the wire from clockwise to counterclockwise directions.
