| titleOfInvention | Trileaflet mechanical prosthetic heart valve |
| abstract | A mechanical prosthetic heart valve having a ring, multiple hinges, and multiple leaflets. The hinges are attached to the ring and are evenly spaced from one another along the inner circumference of the ring. Each leaflet is rotably attached to a hinge by an opening located in the center of the lower portion of the leaflets. The ring can include multiple protrusions located along the inner circumference of the ring. The protrusions of the ring limit the opening angle of the leaflets. By limiting the opening angle of the leaflets, wear and tear of the hinges and leaflets, as well as the probability of malfunction of the mechanical prosthetic heart valve are reduced. In addition, limiting the opening angle of the leaflets may increase the opening and closing speed of the leaflets, thus improving performance of the mechanical prosthetic heart valve when the patient is experiencing an elevated cardiac frequency. |
