Abstract:
1. A method for securing a prosthetic device in a body passage comprising: folding a resilient, deformable annular ring, having radii, to assume a first configuration having a cross-sectional area smaller than the cross-sectional area of an undeformed ring, said ring comprising a bundle of closely associated, concentric, radially overlapping windings formed of a strand of wire and overlapping in the directions of said radii, the diameter of said bundle of windings corresponding with the diameter of said ring, said ring attached to and coaxial with a free end of a tubular graft; positioning said ring at a desired position within a body passage; and allowing said ring to resiliently deform to a second configuration having a larger cross-sectional area than in said first configuration, but still having a cross-sectional area smaller than that of said undeformed ring.
