摘要:
Among other things, a heart tissue support has a ring-shaped body and gripping elements, each gripping element having a free end that is sharp enough to penetrate heart tissue when pushed against the tissue, and a feature to resist withdrawal of the gripping element from the tissue after the sharp free end has penetrated the tissue. Among other things, a tool to attach a support to a heart valve annulus has splaying elements that spread apart to hold the support in an expanded configuration prior to attachment. Among other things, an apparatus includes polygonal elements connected along corners of the elements to form a ring, the polygonal elements being capable of expanding and contracting, and gripping elements attached to points of the polygonal elements. Among other things, a method includes using a delivery tool to expand a support and a heart valve annulus to one diameter.
