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.

Claims

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.

2. The system of claim 1 wherein the cardiac valve prosthesis is an aortic valve prosthesis.

3. The system of claim 1 wherein the plurality of radially expandable portions include an annular inflow portion, associated with blood inflow, and an annular outflow portion, associated with blood outflow.
