摘要： A prosthetic valve includes an expandable valve frame and leaflets supported therein. A plurality of elongate anchor arms extends from an outlet end portion of the valve frame. Each elongate anchor arm includes anchoring protrusions, such as barbs, for engaging surrounding tissue. During delivery to the treatment site, the anchoring protrusions face inwardly. When released from the delivery catheter, the anchoring arms evert such that the anchoring protrusions reverse orientation and face outwardly. In this position, the protrusions can engage surrounding tissue and thereby secure the prosthetic valve within a native heart valve.

摘要： Apparatuses, systems, and methods for prosthetic valves. Embodiments of prosthetic valves may include sealing bodies configured for an anchor to at least partially pass through. The pass through may allow for the sealing body to seal to a portion of a patient's heart in the event of a miscapture of a leaflet by the anchor. Embodiments may include modular valve systems and prosthetic valves including anchors for coupling to chordae, trabeculae, or papillary structures of a patient's heart. Embodiments may include prosthetic valves including anchors for engaging calcification of a patient's native valve.

摘要： A prosthesis can be configured to grasp intralumenal tissue when deployed within a body cavity and prevent axial flow of fluid around an exterior of the prosthesis. The prosthesis can include an expandable frame configured to radially expand and contract for deployment within the body cavity and a valve body. The expandable frame can include a frame body and a supplemental frame. The valve body can include a plurality of leaflets and one or more intermediate components. The one or more intermediate components can couple at least a portion of the leaflets to the expandable frame. The prosthesis can include an annular flap positioned around an exterior of the expandable frame.

摘要： A heart valve prosthesis for replacing a native mitral valve includes a self-expanding frame with a plurality of anchoring members disposed along the lower region. A valve body is positioned within the self-expanding frame and includes a plurality of leaflets configured to allow blood flow through the self-expanding frame in only one direction. A skirt surrounds the self-expanding frame and is spaced apart therefrom for contacting surrounding tissue and impeding blood flow around the self-expanding frame. The skirt may be reinforced with wires to help maintain a desired shape. The leaflets in the valve body are preferably connected to the self-expanding frame through one or more intermediate components such that the valve body is spaced radially inwardly from an inner surface of the self-expanding frame.

摘要： 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.

摘要： 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.

摘要： Apparatuses, systems, and methods for prosthetic valves. Examples of prosthetic valves may be configured to anchor to an interior surface of a heart valve. Such prosthetic valves, in examples, may include a single frame that supports a plurality of prosthetic valve leaflets. In examples, multiple frames may be utilized to anchor to a heart valve and one or more of the frames may support a plurality of prosthetic valve leaflets.
