TRANSSEPTAL DELIVERY SYSTEM
First Claim
1. 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 sheath catheter slidably disposed over the inner guidewire 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 operably coupled with the inner guidewire catheter and the sheath catheter, wherein actuation of the actuator mechanism in a first direction moves the proximal capsule away from the distal capsule thereby removing a constraint from the prosthesis and allowing the prosthesis to expand, andwherein actuation of the actuator mechanism in a second direction opposite the first direction moves the proximal capsule into engagement with the distal capsule thereby enclosing the prosthesis therein.

Abstract
A delivery system includes a delivery catheter with a capsule configured to carry a prosthesis and a steering catheter for steering the delivery catheter. The delivery catheter can be advanced through a patient'"'"'s vasculature to a target treatment area. The capsule can be opened and the prosthesis can be deployed into the target treatment area. Additionally, a method for delivering a prosthesis to a target treatment area includes advancing a delivery catheter through a patient'"'"'s vasculature to the target treatment area, steering the delivery catheter toward the target treatment area, opening a capsule on the delivery catheter, and deploying the prosthesis into the target treatment area.
