  • Patent number: 11813161
    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.

  • Patent number: 11730614
    Abstract: The present disclosure relates generally to stents, systems, and methods for anchoring devices within a body lumen by cooperation between the device and the body musculature. A device comprising an elongate tubular member may be deployed within a body lumen, where the body lumen includes a sphincter that regulates flow through the body lumen. The elongate tubular member includes a sleeve formed from a flexible membrane and one or more stents disposed at either or both ends of the sleeve. In some embodiments, the stents may be treatment stents configured to treat a portion of the body lumen. The elongate tubular member may be deployed within the body lumen such that the flexible membrane aligns with and moves in coordination with the sphincter, thereby increasing retention forces acting upon the elongate tubular member when the sphincter is closed to minimize treatment stent migration.
