  • Optimization of replacement heart valve leaflets
    Patent number: 11337798
    Abstract: A method for optimizing a shape of a replacement valve leaflet, wherein the shape of the replacement valve leaflet is determined by defining variable parameters of the replacement valve leaflet. The variable parameters may comprise: a valve height; a leaflet coaptation height, a first set of two control points for a first B-spline plane of symmetry; and a second set of two control points for a second B-spline plane tangent to a frame of the valve. The method may further comprise creating iterations of potential shapes of the replacement valve leaflet by changing one or more of the variable parameters using modeling software. The method may also comprise calculating the maximum stresses or strains on each of the potential shapes.
