Abstract: A system for deploying a valve prosthesis having a deployment device configured to deploy a valve prosthesis. The deployment device including a catheter body, a tension cable, a capsule, a handle, and a deployment assist. The catheter body having a proximal end and a distal end, the body includes a lumen extending a length of the catheter body. The tension cable being positioned within the catheter body. The capsule having a delivery configuration and a deployed configuration, the capsule being positioned at the distal end of the catheter body and coupled to the first end of the tension cable, wherein the tension cable inhibits the capsule from transitioning between the delivery configuration and the deployed configuration. The handle is positioned at the proximal end of the catheter body. The deployment assist is positioned at the handle and places a force to help transition the delivery configuration to the deployed configuration.

Abstract: A delivery system for prosthetic heart valves are provided. The delivery system includes a flexible shaft, a distal sheath capsule configured to contain the prosthetic heart valve, an inner steerable catheter including an inner distal flex component, and an outer steerable catheter including an outer distal flex component. The inner distal flex component includes a first cut pattern and a second cut pattern distal to the first cut pattern. The outer distal flex component includes a third cut pattern. The inner steerable catheter is rotatable at least 90 degrees relative to the outer steerable catheter when the third cut pattern of the outer distal flex component is disposed over at least a portion of the first cut pattern of the inner distal flex component and each of the inner steerable catheter and the outer steerable catheter is in the flexed configuration.
