Claim:
1. A deployment system for repair of a body vessel comprising: a prosthesis having a proximal end and a distal end, a first end portion extending to said proximal end, and a second end portion extending to said distal end, each of said end portions of said prosthesis being radially movable between a circumferentially compressed configuration and a circumferentially expanded configuration, wherein each of the second end portion and the first end portion of the prosthesis are configured to be sequentially introduced into respective opposed second and first openings of a body vessel during deployment such that when deployed the prosthesis provides a fluid conduit between the first and second opposed openings, wherein the first end portion of the prosthesis is introduced into the first opening of the body vessel in a first direction and the second end portion of the prosthesis is introduced into the opposed second opening in a second direction that is different from the first direction; an inner sheath circumferentially surrounding said first end portion of the prosthesis to retain said first end portion in the circumferentially compressed configuration, leaving said second end portion of the prosthesis uncovered by the inner sheath; an outer sheath having a lumen extending therethrough configured to receive the prosthesis in the compressed configuration, the outer sheath having a delivery position and a deployed position, where, in the delivery position, the outer sheath retains the second end portion of the prosthesis in the circumferentially compressed configuration and the first end portion of the prosthesis with the inner sheath, and, in the deployed position, the outer sheath is entirely removed from the prosthesis and the inner sheath to allow an expansion of the second end portion of the prosthesis to the circumferentially expanded configuration; a proximal handle coupled to the outer sheath, the outer sheath extending proximally past a proximal end of said inner sheath, wherein said proximal end of said inner sheath terminates within said outer sheath distally from said proximal handle, the proximal handle being operable to axially move the outer sheath relative to the prosthesis and the inner sheath between the delivery and deployed positions, such that when the outer sheath is in the deployment position no portion or component of the prosthesis or the inner sheath is connected to the outer sheath or the proximal handle after the outer sheath is entirely removed from the prosthesis and the inner sheath, the prosthesis and the inner sheath being completely disconnected from the outer sheath and the proximal handle after the outer sheath is entirely removed from the prosthesis and the inner sheath, where the inner sheath is removable from the first end portion of the prosthesis by splitting the inner sheath from a proximal end of the inner sheath to a distal end of the inner sheath to allow an expansion of the first end portion of the prosthesis to the circumferentially expanded configuration, independent to the expansion of the second end portion.
