Device and method for temporary or permanent suspension of an implantable scaffolding containing an orifice for placement of a prosthetic or bio-prosthetic valve
First Claim
1. A surgical kit for improving cardiac function, comprising a scaffold or valve support device implantable inside a patient and dimensioned to be received within a human heart, and fasteners for attaching said scaffold or valve support device to the patient, said scaffold or valve support device having an inner margin or annulus defining an orifice for seating a prosthetic or bio-prosthetic valve and further having an outer margin or annulus that is flexible to conform to a wall of a heart chamber, said outer margin or annulus and said inner margin or annulus being coplanar substantially in their entireties with one another and spaced in their entireties from one another;
- said fasteners for attaching include at least one fastener or fixation mechanism for attaching said outer margin or annulus of said scaffold or valve support device to a heart in a region about a natural mitral valve;
wherein said kit further comprises a placement and positioning mechanism engageable with said scaffold or support device and particularly said outer margin or annulus for conforming said outer margin or annulus to a heart wall, said placement and positioning mechanism including a plurality of manipulator tethers or wires extending to said outer margin or annulus, said manipulator tethers or wires being detachably connected at their distal ends directly to said outer margin or annulus, said manipulator tethers or wires being individually or independently manipulable for locating said scaffold or valve support device in a desired position and conforming said outer margin or annulus to the wall of the heart chamber.

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.

- said fasteners for attaching include at least one fastener or fixation mechanism for attaching said outer margin or annulus of said scaffold or valve support device to a heart in a region about a natural mitral valve;
- 9. A surgical kit or assembly for improving cardiac function, comprising a scaffold or valve support device implantable inside a patient and dimensioned to be received within a human heart, and means for attaching said scaffold or valve support device to the patient, said scaffold or valve support device having an inner margin or annulus defining an orifice for seating a prosthetic or bio-prosthetic valve, said scaffold or valve support device having an outer margin or annulus coplanar with said inner margin or annulus, said outer margin or annulus and said inner margin or annulus being substantially coplanar in their entireties with one another and spaced in their entireties from one another, wherein said means for attaching includes at least one fastener or fixation mechanism for attaching said scaffold or valve support device to a heart in a region about a natural mitral valve, wherein said fastener or fixation mechanism includes at least one tether element for securing said scaffold or valve support device to cordae tendenae of the heart, said tether element being threadable about the cordae tendenae and drawable through said orifice prior to a seating of a prosthetic or bio-prosthetic valve in said orifice, said tether element being pinched or clamped between said inner margin or annulus and said prosthetic valve upon seating thereof, further comprising a plurality of manipulator tethers or wires with distal ends connected directly to said outer margin or annulus and disengageable or detachable therefrom, said manipulator tethers or wires being individually or independently manipulable for locating said scaffold or valve support device in a desired position and conforming said outer margin to an internal tissue surface.
