  • Publication number: 20210228358
    Abstract: A prosthetic venous valve having a conical shaped base valve member and a biomaterial delivery construct. The base valve member includes a plurality of fluid flow modulating means that open and allow antegrade blood to be transmitted out of the valve member when the valve member receives antegrade blood therein, and close and prevent retrograde blood from flowing into the valve member. The biomaterial delivery construct is adapted to receive and position the base valve member therein, and be disposed proximate a luminal wall of a venous vessel.

  • Publication number: 20210196859
    Abstract: Cardiovascular prostheses for treating, reconstructing and replacing damaged or diseased cardiovascular tissue that include a plurality of particulate structures. The particulate structures further include an acellular ECM core and an outer layer or coating comprising poly(glycerol sebacate) (PGS) and everolimus.

  • Patent number: 11045580
    Abstract: An implantable medical product and method of use for substantially reducing or eliminating harsh biological responses associated with conventionally implanted medical devices, including inflammation, infection and thrombogenesis, when implanted in in a body of a warm blooded mammal. The bioremodelable pouch structure is configured and sized to receive, encase and retain an electrical medical device therein and to allow such device to be inserted into the internal region or cavity of the pouch structure; with the pouch structure formed from either: (a) first and second sheets, or (b) a single sheet having first and second sheet portions. After receiving the electrical device, the edges around the opening are closed by suturing or stapling. The medical device encased by the bioremodelable pouch structure effectively improves biological functions by promoting tissue regeneration, modulated healing of adjacent tissue or growth of new tissue when implanted in the body of the mammal.

  • Publication number: 20210169643
    Abstract: Prosthetic heart valves having a conical shaped base valve structure formed from collagenous mammalian tissue. The base valve structure includes a plurality of elongated ribbon members that are positioned proximate each other in a joined relationship, wherein the elongated ribbon members are positioned adjacent each other and form a plurality of fluid flow modulating regions that open when fluid into and through the base valve structure exhibits a positive pressure relative to the exterior pressure, i.e., a positive pressure differential, wherein the fluid is allowed to be transmitted out of the base valve structure, and transition to a closed configuration when the pressure differential between the interior valve pressure and exterior pressure reduces, wherein the fluid is restricted from flowing out of the base valve structure.

  • Patent number: 10993802
    Abstract: A biocompatible and biodegradable construct having a base expandable member and an integral, internal support structure. The support structure is preferably formed from poly(glycerol sebacate) (PGS) or a magnesium alloy. The base member is preferably formed from acellular extracellular matrix (ECM) derived from small intestine submucosa (SIS) tissue that exhibits a flexible, porous, sponge-like structure adapted to expand upon absorption of a bodily fluid, wherein the construct seals a perivalvular leak when disposed proximate thereto.

  • Patent number: 10952845
    Abstract: A percutaneous transseptal surgical implantation method for replacing a defective atrioventricular (AV) valve with a conical shaped prosthetic valve formed from extracellular matrix (ECM) tissue. When the method is employed to replace a native mitral valve, the method positions the prosthetic tissue valve in the mitral valve region, whereby the valve does not obstruct the outflow tract of the aortic valve and prevents the leaflets of the aortic valve from coapting.
