Abstract
In a surgical method for improving cardiac function, an implantable scaffold or valve support device is inserted inside a patient's heart and attached to the heart in a region adjacent to a natural mitral or other heart valve. The scaffold or valve support device defines an orifice and, after the attaching of the scaffold or valve support device to the heart, or temporary support while native valve leaflets and/or subvalvular structures are captured, a prosthetic or bio-prosthetic valve seated in the orifice, and the native valve may be retracted into the scaffold/replacement assembly to create a gasket for sealing the complex.
Claims13
An implantable device for use in valve placement in a subject, the device comprising:
- a main body member defining an orifice for receiving or seating a prosthetic or bio-prosthetic valve;
- at least one fastener connected at least indirectly to said main body member for attaching said main body member to leaflets of a native valve, said at least one fastener including an entrainment component and at least one elongate flexible tensile coupling element connected to said main body member and carrying said entrainment component at a free end spaced from said main body member, said coupling element being of sufficient length to extend, from said main body member spaced from the native valve, through a natural opening of said native valve located between said valve leaflets;
- and
- a plurality of flexible elongate suspension elements connected to said main body member at intervals along a circumference thereof, said flexible elongate suspension elements being provided at respective free ends, opposite said main body member, with fasteners for attaching said main body member to a cardio-vascular wall proximate to said native valve,
- said plurality of flexible elongate suspension elements being primary tether elements, further comprising a plurality of secondary tether elements extending to distal or free ends of said suspension elements for positioning said distal or free ends and fixing said distal or free ends to a cardio-vascular wall proximate to said native valve.

An implantable device for use in valve placement in a subject, the device comprising:
- a main body member defining an orifice for receiving or seating a prosthetic or bio-prosthetic valve;
- and
- at least one fastener connected at least indirectly to said main body member for attaching said main body member to leaflets of a native valve, said at least one fastener including an entrainment component and at least one elongate flexible tensile coupling element connected to said main body member and carrying said entrainment component at an end spaced from said main body member, said coupling element being of sufficient length to extend, from said main body member spaced from the native valve, through a natural opening of said native valve located between said valve leaflets,
- said coupling elements being movably attached to said main body member initially for motion alternately in a distal direction and a proximal direction relative to said main body member,
- wherein said coupling elements and said main body member are provided with cooperating ratchet components for preventing the hooks, barbs, or other entrainment components at the distal ends of said coupling elements from moving away from said main body member once said main body member is advanced a predetermined distance over said coupling elements towards the hooks, barbs, or other entrainment components, whereby said main body member is locked into position and cannot be separated from said valve leaflets upon engagement of said main body member with the valve leaflets.

An implantable device for use in valve placement in a subject, the device comprising:
- a main body member defining an orifice for receiving or seating a prosthetic or bio-prosthetic valve;
- a plurality of flexible elongate suspension elements each connected at a first end of two opposing ends to said main body member at intervals along a circumference thereof;
- and
- a plurality of fasteners each disposed at a second end of a respective one of said flexible elongate suspension elements, opposite said main body member and spaced in their entirety therefrom, for attaching said main body member to a cardio-vascular wall spaced from an annulus of said native valve via said flexible elongate suspension elements,
- wherein said flexible elongate suspension elements are primary tether elements, further comprising a plurality of secondary tether elements extending to said second ends of said primary tether elements for positioning said second ends and fixing said second ends via said fasteners to a cardio vascular wall spaced from the annulus of said native valve.
