Abstract: A delivery system is provided for deploying a prosthesis in a body lumen, the prosthesis having a radially compressed configuration. The delivery system includes a primary elongated member positioned coaxially within the prosthesis. A secondary elongated member surrounds a portion of the primary elongated member and a portion of the secondary elongated member is positioned coaxially within the prosthesis. The delivery system further includes a proximal anchor attached to the secondary elongated member. The anchor is adapted for engagement with the proximal end of the prosthesis, thereby maintaining the prosthesis in its radially compressed configuration. At least one outer sheath is adapted to be retracted to expose the prosthesis while the prosthesis is maintained in its radially compressed configuration.
