The present invention includes a coiled wire (10) formed of a shape memory material for implantation into an anatomical defect. After implantation of one or more of the coiled wires (10) according to the present invention, the defect is occluded and thereby corrected or treated. Prior to implantation, the coiled wire (10) is generally elongated and thereafter it reverts to a predetermined shape that is suitable for occluding the defect. At least one clip having at least two prongs may be provided on the wire for attachment to body tissue. Preferably the wire is made of nickel-titanium. In an alternative embodiment, the coil (10) includes a plurality of layers. At least one of these layers is formed of a shape memory material.
