  • Patent number: 10524911
    Abstract: An annuloplasty repair segment for heart valve annulus repair. In one embodiment a multi-stranded cable replaces solid core wire for both the tricuspid and mitral valves. Cable allows for greater deployment flexibility for minimally-invasive surgical (MIS) implant, while still maintaining the required strength and similar tensile properties of solid-core wire. In addition, selective placement of point-welds or other such control points locally control other parameters such as the amount and direction of displacement as the ring undergoes external loading. Cable with well-placed control points result in a MIS annuloplasty ring with sufficient flexibility in the x-y plane to allow a surgeon to squeeze the ring into a small incision, such as for example 1 cm×1 cm, while maintaining structural rigidity under forces exerted on the implanted ring by the cardiac cycle and allowing for asymmetrical deflection to be designed into the product.

  • Patent number: 10478301
    Abstract: The invention is a cardiac implant, and associated methods therefore, configured to repair and/or replace a native heart valve, and having a support frame configured to be reshaped into an expanded/changed form in order to receive and/or support an expandable prosthetic heart valve therein. The implant may be configured to have a generally rigid and/or expansion-resistant configuration when initially implanted to replace/repair a native valve (or other prosthetic heart valve), but to assume a generally non-rigid and/or expanded/expandable form when subjected to an outward force such as that provided by a dilation balloon. The implant may be configured to have a generally D-shaped configuration when initially implanted, but to assume a generally circular form when subjected to an outward force such as that provided by a dilation balloon.
