Abstract
Biologically implantable prostheses and methods of using the same are disclosed. In one embodiment, a heart valve assembly includes a first annular prosthesis sized for introduction into a tissue annulus in a heart; a first magnet in the first prosthesis; a second valve prosthesis separate and disconnected from the first prosthesis and comprising a heart valve crown with leaflets, the second prosthesis configured for introduction into the tissue annulus after introducing the first prosthesis into the tissue annulus; and a second magnet in the second prosthesis, wherein an attraction between the first magnet and the second magnet engages the first prosthesis to the second prosthesis to attach the second prosthesis to the first prosthesis in the tissue annulus.
