A delivery system for delivering a prosthesis to a target treatment area, said system comprising: an inner guidewire catheter having a proximal end, a distal end, and a lumen extending therebetween, the lumen sized to slidably receive a guidewire; a distal capsule coupled to the distal end of the inner guidewire catheter , wherein the distal capsule comprises an inner channel sized to receive the prosthesis ; a bell catheter slidably disposed over the inner guidewire catheter , the bell catheter having a bell element adjacent a distal end of the bell catheter ; an anchor catheter slidably disposed over the bell catheter , the anchor catheter having an anchor element adjacent a distal end of the anchor catheter and configured to engage the prosthesis , and wherein the bell element is configured to constrain the prosthesis into engagement with the anchor element; a sheath catheter slidably disposed over the anchor catheter , the sheath catheter having a proximal end and a distal end; a proximal capsule coupled to the distal end of the sheath catheter , wherein the proximal capsule comprises an inner channel sized to receive the prosthesis ; and an actuator mechanism comprising a distal actuator and a proximal actuator , the actuator mechanism operably coupled with the inner guidewire catheter and the sheath catheter , wherein actuation of the distal actuator in a first direction moves the proximal capsule away from the distal capsule and wherein actuation of the proximal actuator moves the bell element away from the anchor element , thereby removing a constraint from the prosthesis and allowing the prosthesis to expand, and wherein actuation of the proximal actuator or the distal actuator in a second direction opposite the first direction moves the proximal capsule into engagement with the distal capsule thereby enclosing the prosthesis therein. an inner guidewire catheter having a proximal end, a distal end, and a lumen extending therebetween, the lumen sized to slidably receive a guidewire; a distal capsule coupled to the distal end of the inner guidewire catheter , wherein the distal capsule comprises an inner channel sized to receive the prosthesis ; a bell catheter slidably disposed over the inner guidewire catheter , the bell catheter having a bell element adjacent a distal end of the bell catheter ; an anchor catheter slidably disposed over the bell catheter , the anchor catheter having an anchor element adjacent a distal end of the anchor catheter and configured to engage the prosthesis , and wherein the bell element is configured to constrain the prosthesis into engagement with the anchor element; a sheath catheter slidably disposed over the anchor catheter , the sheath catheter having a proximal end and a distal end; a proximal capsule coupled to the distal end of the sheath catheter , wherein the proximal capsule comprises an inner channel sized to receive the prosthesis ; and an actuator mechanism comprising a distal actuator and a proximal actuator , the actuator mechanism operably coupled with the inner guidewire catheter and the sheath catheter , wherein actuation of the distal actuator in a first direction moves the proximal capsule away from the distal capsule and wherein actuation of the proximal actuator moves the bell element away from the anchor element , thereby removing a constraint from the prosthesis and allowing the prosthesis to expand, and wherein actuation of the proximal actuator or the distal actuator in a second direction opposite the first direction moves the proximal capsule into engagement with the distal capsule thereby enclosing the prosthesis therein. <EOS>
