1. A device or assembly for use in heart valve placement in a subject, the device or assembly comprising an implantable scaffold including:
- an inner margin element defining an orifice for receiving or seating a prosthetic or bio-prosthetic valve; and
a flexible outer margin element conformable to an irregular internal wall surface of a heart chamber, said outer margin element surrounding said inner margin element, said outer margin element and said inner margin element being different from one another and spaced in their entireties from one another, said outer margin element and said inner margin element being coplanar substantially in their entireties with one another, the device or assembly further comprising a placement and positioning mechanism engageable with said scaffold and particularly said outer margin element for conforming said outer margin element to an irregularly shaped tissue surface, said placement and positioning mechanism including a plurality of manipulator tethers or wires extending to said outer margin element, said manipulator tethers or wires being detachably connected at their distal ends directly to said outer margin element, said manipulator tethers or wires being individually or independently manipulable for locating said scaffold in a desired position and conforming said outer margin element to an internal tissue surface.

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 about a natural mitral valve. The scaffold or valve support device defines an orifice and, after the attaching of the scaffold or valve support device to the heart, a prosthetic or bio-prosthetic valve is seated in the orifice. The scaffold or valve support device is at least indirectly secured to cordae tendenae of the heart.
