    Abstract: A system includes a core and a catheter for use with (A) a first atrial arm and a first ventricular arm articulatable with respect to each other at a first articulation site to clamp one leaflet of a patient's native heart valve, and (B) a second atrial arm and a second ventricular arm articulatable with respect to each other at a second articulation site to clamp another native leaflet of the native valve. The core tapers in a distal direction toward its smallest perimeter, defining a minimum nonzero angle of the atrial arms with respect to a central longitudinal axis of the core. The catheter advances the core and the arms toward the native valve. The catheter and the core have an advancement configuration in which the smallest perimeter of the core is adjacent to the first and second articulation sites. Other embodiments are also described.

    Abstract: A transluminal sheath is advanced into a femoral vein of a subject, through an inferior vena cava of the subject, into a right atrium of a heart of the subject, and transseptally into a left atrium of the heart. A surrounding-sheath is advanced out of a distal end of the transluminal sheath, into the left atrium, and toward a commissure of a mitral valve of the heart. A commissural helix is implanted at the commissure by advancing the commissural helix out of the surrounding-sheath and through the commissure into a left ventricle of the heart, such that the commissural helix wraps around at least some chordae tendineae at the commissure and facilitates sealing of the commissure. Subsequently to the implantation of the commissural helix, the surrounding-sheath is extracted from the heart. Other embodiments are also described.

    Abstract: Implantable first atrial and ventricular arms are articulatable at a first articulation site to clamp a first heart valve leaflet. A first implantable elongate transitioning member is (a) connected at a fixed connection point at a portion of the first ventricular arm farthest from the first articulation site, (b) has a portion that faces an opposite surface of the first ventricular arm, and (c) is controllable to move the first ventricular arm. Implantable second atrial and ventricular arms are articulatable at a second articulation site to clamp a second leaflet. A second implantable elongate transitioning member is (a) connected at a fixed connection point at a portion of the second ventricular arm farthest from the second articulation site, (b) has a portion that faces an opposite surface of the second ventricular arm, and (c) is controllable to move the second ventricular arm. Other embodiments are also described.

    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: Apparatus is provided for use with a native valve of a heart of a subject. The apparatus includes: (1) an annular upstream support portion, comprising an expandable first frame, the upstream support portion configured to be placed against an upstream surface of the native valve; (2) a flexible polyester connector; and (3) an anchoring element, flexibly coupled to the upstream support portion by the connector, and configured to anchor the upstream support portion to the native valve by engaging tissue of the native valve.

    Abstract: For some applications, apparatus is provided for facilitating implantation of a prosthetic valve at a native heart valve of a subject, the apparatus comprising a prosthetic valve support, the prosthetic valve support (a) being configured to be transluminally-deliverable to the native valve and to be deployable at the native valve, and (b) comprising one or more tissue-engaging elements, configured to couple the prosthetic valve support to leaflets of the native valve without eliminating check valve functionality of the native valve. Other embodiments are also described.
