Patent ID: 8025695

Claim:
A biologically implantable system for a heart valve, comprising: a first prosthesis comprising an annular ring implantable directly and independently into an annulus of a heart, the first prosthesis comprising a circumference and a fabric covering, the annular ring having a circular latitudinal cross-section perpendicular to a central longitudinal axis; a second prosthesis comprising a heart valve crown, the second prosthesis further comprising a circumference including a fabric covering thereon, the crown comprising an annular frame carrying leaflets, the frame having a latitudinal cross-section in a plane perpendicular to the central longitudinal axis defining multiple lobes separated by scallops, the scallops being disposed closer to the central longitudinal axis within the plane than the lobes; and at least one engagement element disposed on the circumferences of the first and second prostheses that self-engage one another when the second prosthesis is inserted into engagement with the first prosthesis after the first prosthesis is implanted within an annulus of a heart.
