International Classification:

A61F 2/24

US Classification:

623 237

Abstract:

Devices and related methods of use are provided for improving heart function. In one embodiment of the present disclosure, a device includes a ring-like structure configured to be secured to a heart valve; at least one elongate member extending from the ring-like structure, wherein an end of the elongate member is configured to be secured to heart geometry other than a heart valve; and an adjustment mechanism for simultaneously altering a dimension of the ring-like structure and a length of the elongate member.

International Classification:

A61F 2/24

US Classification:

623 211, 623 21, 623 213

Abstract:

A valved conduit including a bioprosthetic valve, such as a heart valve, and a tubular conduit sealed with a bioresorbable material. The bioprosthetic heart valve includes prosthetic tissue that has been treated such that the tissue may be stored dry for extended periods without degradation of functionality of the valve. The bioprosthetic heart valve may have separate bovine pericardial leaflets or a whole porcine valve. The sealed conduit includes a tubular matrix impregnated with a bioresorbable medium such as gelatin or collagen. The valved conduit is stored dry in packaging in which a desiccant pouch is supplied having a capacity for absorbing moisture within the packaging limited to avoid drying the bioprosthetic tissue out beyond a point where its ability to function in the bioprosthetic heart valve is compromised. The heart valve may be sewn within the sealed conduit or coupled thereto with a snap-fit connection.
