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 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.

Abstract: Methods and devices for transvascular prosthetic chordae tendinea implantation are disclosed. A catheter is advanced into the left atrium, through the mitral valve, and into the left ventricle. A ventricular anchor is deployed from the catheter and into a wall of the left ventricle, leaving a ventricular suture attached to the ventricular anchor and extending proximally through the catheter. A leaflet anchor is deployed to secure a mitral valve leaflet to a leaflet suture, with the leaflet suture extending proximally through the catheter. The leaflet suture is secured to the ventricular suture to limit a range of travel of the leaflet in the direction of the left atrium. Also disclosed is an assembled in situ mitral valve leaflet restraint, having a neo papillary muscle and a neo chordae tendinea.

Abstract: Various exemplary systems and devices for knotless anchor insertion and methods of knotless anchor insertion are provided. In general, an inserter tool is configured for knotless anchor insertion in a soft tissue repair surgical procedure. The inserter tool is configured to insert an anchor into a bone of a patient to secure a soft tissue relative to the bone. A suture coupled to the soft tissue is secured relative to the bone by being trapped between an exterior surface of the anchor and a bone surface defining a hole in the bone in which the anchor is positioned.

Abstract: A suture anchor method including a suture anchor and a suture anchor drive. The suture anchor is positionable on a rod of the suture anchor drive. The rod defines an awl for forming a hole in a bone. The suture anchor drive further has an impactor for moving the suture anchor along the rod between a retracted position and an advanced position so as to implant the suture anchor in the bone with the awl positioned in the bone.

Abstract: A catheter device includes a tube, and an extracorporeal unit coupled to a proximal end of the tube. An implant includes a series of anchors and a tether. The series of anchors includes a first anchor and other anchors, arranged along the extracorporeal unit. Each of the anchors includes a tissue-engaging element, and a head that defines an eyelet. The tether extends, along the extracorporeal unit, through the eyelet of each of the other anchors to the first anchor such that (i) the first anchor is advanceable, with a distal end of the tether, distally into and through the tube toward the tissue, and (ii) subsequently, the other anchors are slidable, sequentially, over and along the tether, distally into and through the tube toward the first anchor. Other applications are also described.

Abstract: Methods and devices for transvascular prosthetic chordae tendineae implantation are disclosed. A catheter is advanced into the left atrium. From an atrium side, a leaflet anchor having a leaflet suture is secured to the mitral valve leaflet. A ventricular anchor is anchored to the wall of the ventricle to secure the ventricular wall to a ventricle suture. The leaflet suture and the ventricle suture may be tensioned and connected by a suture lock to form an artificial chordae. The suture lock has a body with a suture path extending therethrough. A wall in the housing is movable to reduce the cross section of the suture path. A drive mechanism advances the movable wall to clamp sutures extending through the suture path, in response to rotation of a coupling on the housing.

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.

Abstract: A device for sealing a left atrial appendage includes an anchor element, a sealing element, and a coupling element. The anchor element is configured to anchor the device to tissue in or adjacent the left atrial appendage. The sealing element is configured to seal the left atrial appendage and prevent thrombus from embolizing therefrom. The coupling element joins the anchor element with the sealing element. A delivery catheter may be used to deliver the sealing device.
