  • Foldable Prosthetic Heart Valve
    Publication number: 20240033077
    Abstract: A prosthetic heart valve is constructed from a flexible substrate that can be folded from an unfolded configuration to a folded configuration, in which the prosthesis is operable as a prosthetic heart valve. The prosthetic heart valves can be designed as atrioventricular valves (e.g., tricuspid valve, mitral valve) or as semilunar valves (e.g., aortic valve, pulmonary valve).

  • Photovoltaics using concave surface column array to enhance sunlight absorption
    Patent number: 9385165
    Abstract: A photovoltaic device forming a solar cell includes a first surface on a first column and a second surface on a second column, wherein the first surface is applied with a first light absorption media and the second surface is applied with a second light absorption media. The first surface and the second surface form a resonance cavity that can trap incident light entering to enhance light absorption.
