Abstract: A stent comprises a network of elastically deformable struts having a biased cross-sectional shape and forming a first end portion having a first central diameter in a major dimension and a second central diameter in a minor dimension, wherein the first central diameter is greater than the second central diameter, a second end portion having the first central diameter in the major dimension and the second central diameter in the minor dimension, and a middle portion situated between the first end portion and the second end portion, the middle portion having a third central diameter in the major dimension and the second central diameter in the minor dimension, the third central diameter being less than the first central diameter.

Abstract: An implant for adding compliance to a blood vessel includes a first elongate rail shaped to contact an inner wall of a blood vessel and a second elongate rail shaped to contact an opposing inner wall of the blood vessel. Connectors extend between the first and second rails for providing a separation therebetween and maintaining the rails at locations on opposing sides of the lumen after implantation. The connectors push the rails outwardly for biasing the blood vessel toward a substantially oval shape. The connectors are preferably flexible for allowing the blood vessel to change shape during use for adding compliance to the blood vessel. The elongate rails are preferably curved or hemi-spherical for conforming to the shape of the inner wall of the blood vessel.
