    Abstract: A transluminal sheath is advanced transseptally into a left atrium of the subject. A distal end of a surrounding-sheath, having an anchor disposed therein, is advanced via a distal end of the transluminal sheath, into a left ventricle of the subject via a commissure of the mitral valve. While the distal end of the surrounding-sheath is in the left ventricle, the surrounding-sheath is pulled proximally with respect to the anchor to expose the anchor. While the distal end of the surrounding-sheath is in the left ventricle, mitral valve tissue that is within the left ventricle is encircled by helically wrapping the anchor around the mitral valve tissue. Subsequently, the surrounding-sheath is extracted from the heart. Other embodiments are also described.

    IPC: A61F2/24

    Abstract: A prosthetic valve includes a tubular valve body, snares, and an upstream support. A native valve of a heart of a subject is disposed between an atrium and a ventricle of the heart, and has an annulus and leaflets. The prosthetic valve is advanced to the heart while in a compressed state. The prosthetic valve is positioned within the heart such that the snares are disposed upstream of the annulus and leaflets. The snares are expanded radially outwardly upstream of the leaflets. Subsequently, the prosthetic valve is moved in a downstream direction such that the snares become disposed downstream of the leaflets. While the snares remain downstream of the leaflets, the upstream support is expanded within the atrium, and the upstream support is placed against an upstream surface of the annulus. Other embodiments are also described.

    Abstract: A method is provided, including (1) identifying the subject as having mitral valve regurgitation; (2) during a medical procedure, in response to identifying the subject as having mitral valve regurgitation, implanting a prosthetic valve at a mitral valve site of the heart; and (3) during the same medical procedure, implanting a therapeutic septal device at a septum of the heart. Other embodiments are also described.

    IPC: A61F2/24

    Abstract: An apparatus for use with a prosthetic heart valve at a native heart valve comprises an adjustable-lumen prosthetic valve support. In a delivery state, the prosthetic valve support is transluminally deliverable to the heart. The prosthetic valve support is transitionable, within the heart, into an implantation state for implantation at the native valve. In the implantation state, the prosthetic valve support has an inner edge that defines a lumen through the prosthetic valve support, the lumen having a first diameter. After the prosthetic valve support is implanted at the native valve, the prosthetic valve support is transitionable into an enlarged state in which the lumen has a second diameter that is greater than the first diameter. In the enlarged state, the prosthetic valve support is configured to support, at the native valve, the prosthetic heart valve within the lumen.

    Abstract: Prosthetic heart valves and methods of use of prosthetic heart valves may be provided. In one implementation, a prosthetic heart valve may include an annular spacer configured for implantation with a native heart valve opening and a central valve section configured for disposal within the annular spacer. The central valve section may include at least one anchoring protrusion configured to anchor the central valve section against axial movement relative to the annular spacer. During deployment, the central valve section may be advanced downstream beyond the implanted annular spacer, and moved upstream until the anchoring protrusion engages the annular spacer.

    Abstract: During a medical procedure, a transseptal fenestration is made at a septum of the heart and a shunt is implanted into the transseptal fenestration. During the same medical procedure, a transapical puncture is made into a left ventricle of the heart. A prosthetic valve is delivered via the transapical puncture and implanted at a mitral valve of the heart. Subsequently to delivering the prosthetic valve and making the transseptal fenestration, the transapical puncture is closed. Other embodiments are also described.

In one implementation, a prosthetic heart valve may include an annular spacer configured for implantation with a native heart valve opening and a central valve section configured for disposal within the annular spacer. The central valve section may include at least one anchoring protrusion configured to anchor the central valve section against axial movement relative to the annular spacer. During deployment, the central valve section may be expanded radially within the heart into an at least partially-expanded configuration while at least a portion of the central valve section is situated outside of a space opening of the annular spacer, and moved upstream while remaining in the at least partially-expanded configuration until the anchoring protrusion engages the annular spacer.
