Biologically implantable prosthesis
First Claim
1. A heart valve assembly comprising:
- a first annular prosthesis configured to be implanted into a tissue annulus in a heart such that the first prosthesis includes a circular wall having an inner surface and an outer surface;
wherein the outer surface is configured to abut the tissue annulus;
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 inner surface of the first prosthesis in the tissue annulus.
