Abstract
Among other things, a tool to attach a support to a heart valve annulus includes a stabilizing body that includes features to stabilize an axial position of the tool relative to the annulus, and an attachment device connected to the stabilizing body, the stabilizing body and the attachment device being movable relative to one another under control from a location remote from the tool. The support may have an expandable tubular body having a plurality of struts, a plurality of tissue anchors extending from distally facing apexes in a distal direction post-deployment, wherein axial distal advance of the implantable annulus support causes the plurality of tissue anchors to axially engage tissue, and the implantable annulus support is self-contractible from a radially enlarged engagement configuration for engaging tissue of the mitral valve annulus, to a reduced, deployed configuration for modifying mitral valve annulus geometry.
