  • Patent number: 11517429
    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.

  • Publication number: 20220378410
    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.

  • Patent number: 11484700
    Abstract: Apparatus is provided for treating heart failure, the apparatus including one or more propeller blades and a controller, which is configured to rotate the one or more propeller blades to produce continuous non-pulsatile blood flow not synchronized with a cardiac cycle of a subject. An intra-atrial anchor includes a stent surrounding the one or more propeller blades. The intra-atrial anchor is coupled to the one or more propeller blades and configured to be anchored in a left atrium of the subject so as to position the one or more propeller blades in the left atrium oriented such that the one or more propeller blades, when rotated by the controller, draw blood from the left atrium and expel the blood in the left atrium toward a mitral valve, thereby increasing atrial pressure above the mitral valve. Other embodiments are also described.

  • Patent number: 11426155
    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.

  • Patent number: 11395910
    Abstract: A method for repairing a heart includes identifying a heart of a patient as having a reduced ejection fraction. In response to the identifying, wall stress of a ventricle of the heart is reduced by implanting apparatus that facilitates cyclical moving of fluid that is not blood of the patient into and out of the ventricle of the heart. During ventricular diastole, a volume of the fluid is moved into the ventricle in a manner that produces a corresponding decrease in a total volume of blood that fills the ventricle during diastole. During ventricular systole, the volume of the fluid is moved out of the ventricle in a manner that produces a corresponding decrease in a total volume of the ventricle during isovolumetric contraction of the ventricle. Other embodiments are also described.

  • Patent number: 11357629
    Abstract: A method of treating diastolic heart failure includes implanting a cardiac implant in a heart of a subject diagnosed as suffering from diastolic heart failure. A superior portion of a flexible tether of the cardiac implant is anchored to one or more left-atrial sites of one or more walls of the left atrium. An inferior portion of the flexible tether is anchored to a site of a wall of a mid third of the left ventricle, of a wall of an apical third of the left ventricle, and/or of a papillary muscle of the left ventricle. As a result, the flexible tether reduces a volume of the left atrium during at least a portion of ventricular diastole of each cardiac cycle, thereby enhancing ventricular filling. Other embodiments are also described.
