<p num="1">A delivery system (10) is provided for deploying a prosthesis (12) in a body lumen, the prosthesis having a radially compressed configuration. The delivery system includes a primary elongated member (16) positioned coaxially within the prosthesis. A secondary elongated member (18) 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 (20P) 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 (26) is adapted to be retracted to expose the prosthesis while the prosthesis is maintained in its radially compressed configuration. The primary elongated member and the secondary elongated member are axially movable relative to one another to disengage the prosthesis from the anchor and permit expansion of the radially compressed prosthesis.</p> |
