Method for implanting a heart valve within an annulus of a patient
First Claim
1. A method for implanting a heart valve in a tissue annulus within a patient'"'"'s heart, comprising:
- positioning a first annular prosthesis within the tissue annulus in an unexpanded state, wherein the first annular prosthesis comprises a circular circumference;
expanding the first prosthesis to an expanded state within the tissue annulus to contact surrounding tissue;
fixing the first prosthesis to tissue surrounding the tissue annulus;
introducing a second valve prosthesis into the tissue annulus after fixing the first prosthesis;
introducing a connection adapter into the tissue annulus, the connection adapter including a multi-lobed circumference; and
securing the second prosthesis relative to the first prosthesis within the tissue annulus using the connection adapter.

Abstract
A method for implanting a heart valve assembly includes a first annular prosthesis for implantation within a tissue annulus, a second valve prosthesis, and a multi-lobed connection adapter to secure the second prosthesis to the first prosthesis. In one embodiment, the adapter is arranged to allow the second prosthesis to be secured to the first prosthesis in a predetermined angular orientation. During use, the first annular prosthesis is implanted into the annulus, and the second valve prosthesis is inserted into the annulus. The adapter secures the second prosthesis relative to the first prosthesis to align the second prosthesis with the first prosthesis in a predetermined angular orientation; and secure the second prosthesis to the first prosthesis in the predetermined angular orientation.
