Abstract: The present disclosure includes a device for reshaping a heart valve. The device may include a central ring about a central axis and a plurality of arms coupled to the central ring, each of the arms coupled to the central ring at a pivot point at a first end of the arm, the arm comprising an attachment feature at a second point along the arm, the pivot point configured to allow movement of the arm about the pivot point through a plane extending radially from the central axis through the arm. Additionally, the plurality of arms may be contractable and may be extendable such that the hooks extend beyond a dilated heart valve. The present disclosure also includes associated methods and systems.

Abstract: Disclosed is a novel filter and delivery means. The device described within will not interfere with standard practice and tools used during standard surgical procedures and tools such as cannulas, clamps or dissection instruments including valve replacement sizing gages or other surgical procedures where the patient must be put on a heart-lung machine cross-clamping the aorta.

Abstract: Excessive dilation of the annulus of a mitral valve may lead to regurgitation of blood during ventricular contraction. This regurgitation may lead to a reduction in cardiac output. Disclosed are systems and methods relating to an implant configured for reshaping a mitral valve. The implant comprises a plurality of struts with anchors for tissue engagement. The implant is compressible to a first, reduced diameter for transluminal navigation and delivery to the left atrium of a heart. The implant may then expand to a second, enlarged diameter to embed its anchors to the tissue surrounding and/or including the mitral valve. The implant may then contract to a third, intermediate diameter, pulling the tissue radially inwardly, thereby reducing the mitral valve and lessening any of the associated symptoms including mitral regurgitation.

Abstract: Systems, devices and methods related to various heart valve implants and for delivery of those heart valve implants are described. The implants may be used to re-size a native valve annulus or to replace a native heart valve. The implants include a re-sizable frame having angled struts. Anchors secure the implant to tissue and collars are used to decrease the angle between the struts and contract the frame. The implant thus expands from a first size inside of a delivery catheter, to a second and larger deployed size inside the heart to engage and anchor with the tissue, and then to a third and contracted size to re-size the annulus and/or provide a secure fit for a replacement heart valve. Various delivery systems including imaging capabilities for precise delivery, positioning and anchoring of the various implants are further described.

Abstract: Systems, devices, and methods for adjusting cardiac tissue are described involving adjustment of a frame element of an implantable device relative to the cardiac tissue. At least a component of the implantable device is rotated relative to the cardiac tissue and/or another component of the implantable device. At least a component of the implantable device is axially movable relative to the cardiac tissue and/or another component of the implantable device.

Abstract: Systems, devices and methods for resizing a valve annulus are described. An implant is delivered proximate a mitral valve, the implant comprising a tubular body and a plurality of piercing helical anchors, the tubular body comprising an proximal diameter and a distal diameter. Tissue proximate the mitral valve is engaged by rotating the plurality of anchors with corresponding rotational drivers. The tubular body may be transitioned from a first structural configuration having the proximal diameter smaller than the distal diameter to a second structural configuration having the proximal diameter larger than the distal diameter.
