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: 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.
