International Classification:

A61F 2/24

US Classification:

623002360

Abstract:

An annuloplasty ring including a sheath, an arcuate stiffening element, and a tensioning member. The stiffening element is disposed within the sheath and defines discrete, first and second ends separated by a lateral spacing. The tensioning member extends between the stiffening element ends. The tensioning member is characterized as being more flexible than the stiffening element and is configured to provide a taut state in which the tensioning member is substantially non-extensible and impedes expansion of the lateral spacing. With this configuration, the stiffening element serves to remodel the valve annulus to a desired shape, while the tensioning member exhibits sufficient flexibility to allow for natural movement of the valve annulus while limiting (in the taut state) the extent of annular dilatation (e.g., overt lateral separation of the first and second ends of the stiffening member) due to in vivo forces.

International Classification:

A61F 2/24

Abstract:

A prosthesis includes a tubular graft, a prosthetic valve component, an inflow stent, an outflow stent, and a plurality of body stents disposed between the inflow and outflow stents. Each stent is a sinusoidal patterned radially-expandable ring having a first set of crowns and a second set of crowns, with the first set of crowns disposed closer to an inflow end of the tubular graft than the second set of crowns. The prosthesis is configured to be resistant to backfolding and/or buckling during deployment thereof.
