ABSTRACT:
A prosthesis for treating congenital defects and constrictive diseases in pediatric cases is provided that self-adjusts to accommodate growth of the vessel as the child matures. The prosthesis includes a plurality of spaced apart, self-adjusting, tapered support members that extend from an interconnection member. The prosthesis preferably comprises a nickel-titanium material that exhibits pseudo-elastic behavior at body-temperature, so as to apply an approximately uniform stress to the vessel over a range of expanded diameters. The interconnection member and/or a subset of the support members may include portions defining windows that assist in anchoring the prosthesis within a vessel. Methods of implanting the prosthesis are also provided.
