1. A cardiac valve implantation system for implanting a cardiac valve prosthesis at an implantation site associated with a cardiac valve annulus, the system comprising:
- an expandable cardiac valve prosthesis including a plurality of radially expandable portions and a plurality of valve leaflets;
a deployment instrument including;
a control handle;
a plurality of independently operable deployment elements operable to deploy the plurality of radially expandable portions; and
a delivery device adapted to provide a pathway from outside the patient'"'"'s body for delivery of the deployment instrument to the implantation site.

Abstract
An instrument for deploying a cardiac valve prosthesis, including a plurality of radially expandable portions, at an implantation site, includes a plurality of deployment elements each independently operable to obtain the radial expansion of a radially expandable portion of the valve prosthesis. A method for deploying the cardiac valve prosthesis includes advancing the instrument to an implant site and independently actuating the radially expandable portions.

17. A minimally-invasive method of implanting an expandable cardiac valve prosthesis including an annular inflow portion and an annular outflow portion at an implantation site, the method comprising:
-
positioning the cardiac valve prosthesis in a deployment instrument including first and second independently operable deployment elements associated with the annular inflow portion and the annular outflow portion respectively; advancing the deployment instrument to the implantation site; actuating one of the first and second elements to cause the corresponding annular portion of the prosthesis to expand and engage the implantation site; and actuating the other of the first and second elements to cause the other corresponding annular portion of the prosthesis to expand and engage the implantation site. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)
