1. A prosthesis delivery catheter, comprising:
- a) an elongate inner body having a distal tip;
b) an elongate tubular outer body being disposed about the elongate inner body, the elongate tubular outer body being axially displaceable with respect to the elongate inner body, a distal region of the elongate tubular outer body and the elongate inner body cooperating to define a substantially annular prosthesis chamber for receiving a compressed prosthesis; and
c) a compressed prosthesis disposed about the elongate inner body in the prosthesis chamber, the compressed prosthesis having at least one tether eyelet, the at least one tether eyelet being configured for receiving an elongate tether therethrough; and
d) at least one elongate tether extending along an outside surface of the prosthesis delivery catheter, wherein the at least one tether extends along a first exterior portion of the prosthesis delivery catheter, through the at least one tether eyelet, and along a second exterior portion of the prosthesis delivery catheter, the compressed prosthesis being configured to expand radially outwardly and deployed when the elongate inner body is displaced axially with respect to the elongate tubular outer body to permit the prosthesis to be advanced along the at least one elongate tether toward an anchor that is anchored at an anatomical location where the prosthesis is to be installed.
