Abstract: Devices, systems and methods are described herein to provide improved steerability for delivering a prosthesis to a body location, for example, for delivering a replacement mitral valve to a native mitral valve location. The steerable delivery system can contain a steerable rail configured for multi-plane bending to direct a distal end of the delivery system.

Abstract: Devices, systems and methods are described herein to provide improved steerability for delivering a prosthesis to a body location, for example, for delivering a replacement valve to a native valve location in a heart. Disclosed are a number of features that can improve steerability or release of the prosthesis into the body location. In one preferred delivery system, a proximal handle can be manipulated to apply tension to a pair of diametrically opposed axial runner wires extending through lumens in a wall of a flexible tubular shaft. By applying tension to a pair of axial runner wires, the tubular shaft can be stiffened along a plane extending substantially through the pair of axial runner wires, while the shaft is permitted to freely bend in a perpendicular plane. This feature advantageously provides the ability to adjust the steerability and flexibility of a tubular shaft to meet the requirements of a particular procedure.

Abstract: Devices, systems, and methods relate to implants, such as prosthetic valves for replacing native heart valves. Delivery systems for delivering the implants to an implantation site are also disclosed herein. A prosthetic valve may include a valve body supporting a plurality of prosthetic valve leaflets and one or more adjustable anchors coupled to the valve body for anchoring the prosthetic valve to leaflets of a native heart valve, wherein at least one of the adjustable anchors is axially slidable relative to the valve body for conforming to the native anatomy of the native heart valve.

Abstract: A steerable delivery system is provided for delivering a replacement heart valve to a native heart valve location. The steerable delivery system includes an outer sheath assembly having a capsule along a distal end portion for retaining the replacement heart valve in a compressed configuration. The capsule is constructed to provide both compression resistance and flexibility. The capsule may be formed with an outer polymer layer, a metal middle layer located on a radially inner surface of the outer polymer layer, and an inner liner located on a radially inner surface of the metal middle layer. A fluoroelastomer layer is provided for bonding the inner liner to the metal middle layer. The metal middle layer is preferably a metal hypotube.
