Optimized geometry of a tissue pattern for semilunar heart valve reconstruction
First Claim
1. A two-dimensional valve tissue pattern comprising a configuration that corresponds to the shape of tissue to be used in a reconstruction of at least one leaflet of a circulatory system valve, wherein the pattern comprises a configuration having three lobes arranged about a central coaption point within a central aperture.

Abstract
A new and unique, optimized, two-dimensional heart valve tissue pattern, valve, and a method of reconstructing a three-dimensional semilunar heart valve, or portion thereof. In one preferred embodiment, the two-dimensional valve tissue pattern, and method of the present invention, comprises a two-dimensional configuration developed and optimized by employing, in part, the anatomy of a three-dimensional human heart valve, and said two-dimensional configuration delimits a two dimensional area that corresponds to the shape of tissue to be used in the repair of at least one leaflet of a circulatory system semilunar valve, wherein the configuration delimits at least one segment, and up to all three segments, of a three segment “trefoil” shape.

- 19. A two-dimensional valve tissue pattern comprising a configuration that corresponds to the shape of tissue to be used in the reconstruction of at least one leaflet of a native circulatory system valve, wherein the two-dimensional tissue pattern is reduced to a size which is smaller than the expected size of valve leaflets of a normal valve having a valve annulus of the size of the native circulatory system valve, such that when the tissue pattern is exposed to loads and pressures of the circulatory system, the tissue stretches and substantially conforms to the expected size of a normal valve.
