BIOLOGICALLY IMPLANTABLE PROSTHESIS AND METHODS OF USING THE SAME

摘要

A biological implantable prosthesis (2) is disclosed. The prosthesis (2) can have a circumferentially expandable wall (4) with engagement elements (148) that enable the prosthesis (2) to engage a second prosthesis (68). The prosthesis (2) can be placed accurately into annulus (204) which has an initial annulus diameter (206). The prosthesis (2) can be used to expand the annulus (204) to an expanded annulus diameter (208).
