The present embodiments provide apparatus and methods suitable for coupling a graft member to tissue, closing a bodily opening, and the like. In one embodiment, a tacking device comprises a wire having first and second ends, and further having delivery and deployed states. In the contracted state, the wire comprises an elongated configuration that is substantially parallel to a central longitudinal axis. In the expanded state, the wire comprises a head region and a body region, the head region comprising at least one full turn having a first diameter, and the body region comprising at least two full turns having a second diameter, wherein the first diameter is greater than the second diameter. One or more of the tacking devices may be delivered using a laparoscopic, endoscopic or percutaneous approach.
