Abstract
Abstract The heart support is formed of flat cloth tapes crossing each other at right angles and stitched together to provide a mesh with square openings. The support is heart shaped in outline with a transverse fixation tape having free ends extending laterally in opposite directions from the apex to secure the support to the heart of the patient. Each tape in the mesh is formed of a folded bias weave cloth capable of stretching to conform the support to the shape of the heart.
