Abstract
A prosthesis for use in a human heart as a valve that reduces or eliminates blood stagnation, and therefore, the possibility of thrombosis while increasing available blood flow area through the artificial heart valve without using hinges which can become inoperable due to interaction with blood and human tissue. The artificial heart valve includes a supporting ring, a pair of radially-disposed supporting arms having specially designed and support heads of a particular shape and a pair of semi-circular valve plates that hang from the support arm and engage the support arm heads. The valve plates each include a specially designed slot that receives the support arm head which allows movement of each of the valve plates during operation of the valve to prevent accumulation of human tissue from blocking the operation of the valve. Also, the support ring aperture, in conjunction with the support ring and the mounting of the valve plates has a configuration that aids in blood flow through the valve thereby preventing stagnation and the possibility of thrombosis.
