Abstract: A replacement mitral valve prosthesis includes a support structure and a valve body having three flexible leaflets. The support structure preferably includes an internal valve frame and an external sealing frame. The valve frame supports the flexible leaflets. The sealing frame is adapted to conform to the shape of the native mitral valve annulus. The sealing frame may be coupled to an inlet end of the valve frame, an outlet end of the valve frame, or both. A plurality of anchors are coupled to the outlet end of the valve frame. The anchors extend radially outwardly for placement behind native leaflets. The prosthesis preferably includes a skirt disposed along an exterior of the external sealing frame. The prosthesis is collapsible for delivery into the heart via a delivery catheter. The prosthesis is configured to self-expand for deployment in the heart when released from the delivery catheter.

Abstract: Examples of the present disclosure may be directed to reducing a tension force or a compression force in one or more shafts of the delivery system. An elongate catheter may include the one or more shafts. The tension force or compression force may result from residual tension or compression in a shaft resulting from movement of the shaft. The tension force or compression force may alternatively or in combination result from interacting forces across a plurality of the shafts. The tension force or compression force may hinder the operation of the delivery system and in instances may damage the delivery system. Systems, devices, and methods for reducing the tension force or compression force are disclosed herein.

Abstract: A self-expanding prosthetic heart valve includes an inner frame and an outer sealing frame. A lower region of the outer sealing frame is coupled to a lower region of the inner frame. At least a portion of the outer frame has a D-shape cross-section for conforming to a shape of a native heart valve annulus. Elongate anchors are positioned outwardly from the outer sealing frame for anchoring to native leaflets. Preferably, the native leaflets are secured between the anchors and an outer surface of the outer sealing frame. A valve body is positioned within an interior lumen of the inner frame and provides a one-way valve mechanism for replacing the function of the native leaflets. For additional stability, a further anchoring mechanism may extend from the inner frame for attachment to a heart wall. The prosthetic heart valve is well-suited for replacing the function of a native tricuspid 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.

Abstract: A fabric having a honeycomb weave pattern is provided for use with medical implants. The fabric may be heat treated to increase a thickness and texture of the fabric. The fabric may be compliant and compressible for providing cushioning within a patient's body. For example, the fabric may be applied to a prosthetic valve to cushion a portion of the prosthetic heart valve. The fabric may also be textured to provide enhanced friction between the prosthetic heart valve and the surrounding native tissue. Enhanced friction may be achieved by weave patterns or by the inclusion of protrusions or barbs in the fabric.

Abstract: Disclosed herein are embodiments of a delivery system which can be used to recapture and/or reposition a replacement valve, such as a replacement mitral valve, after initial deployment of the valve. Embodiments of the delivery system can involve a torqueing manifold that interacts with multiple tethers that are releasably coupled to eyelets of a replacement heart valve. Engagement pins may be configured to releasably retain one end of the tethers.
