Cardiac support devices and methods of producing same

Abstract

A pattern for a three dimensional cardiac support device that includes a proximal edge having a concave shape; and a seam edge that includes: first and second sides, wherein said first and second sides are substantially symmetrical along a vertical axis, first and second upward inflection regions, first and second downward inflection regions; and an intersection point. A three dimensional cardiac support device that includes: a pattern, wherein said pattern is substantially symmetrical along a vertical axis, and wherein said pattern includes a proximal edge having a concave shape, and a seam edge that includes: first and second sides, first and second downward inflection regions, first and second downward inflection regions, and an intersection point; and a seam wherein the seam is formed by folding the pattern across the vertical axis and joining the seam edge to itself. A three dimensional cardiac support device formed from a two-dimensional material, wherein the three-dimensional cardiac support device has seams having a seam length, and a surface area, wherein the ratio of the seam length to the surface area is from about 0.1/inch to about 0.2/inch.
