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.
