RECONFIGURING HEART FEATURES

摘要

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, from one configuration in which the support is held in a pre-attachment contracted state to another configuration in which the support is held in an expanded state for attachment at multiple locations around the annulus by action from the remote location. Among other things, an apparatus includes structural elements, and gripping elements, and configuration elements attached to the respective structural elements and each controllable to permit or prevent the ring from expanding.
