Abstract: A mitral valve prosthesis includes an hourglass shaped inner frame and a bulbous outer frame. A valve body having a plurality of leaflets is positioned within an interior region of the inner frame. The leaflets are shaped to substantially conform to an interior surface of the inner frame when the leaflets are in an open position. As a result, the gap between the leaflets and the inner frame is decreased, thereby reducing the likelihood of thrombus formation. Ventricular anchors are preferably provided along a distal end of the inner frame. The anchors extend proximally for placement behind native mitral valve leaflets. A fabric skirt may extend along an inner or outer surface of the outer frame. In preferred embodiments, the fabric skirt extends distally beyond a distal end of the outer frame and is adapted for forming a seal along the mitral valve annulus.

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: 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.

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. Disclosed are a number of features that can improve steerability or release of the prosthesis into the body location.
