Minimally-invasive cardiac-valve prosthesis
First Claim
1. A cardiac-valve prosthesis adapted for percutaneous implantation, the prosthesis comprising:
- an armature adapted for deployment in a radially expanded implantation position, the armature including a support portion and an anchor portion, which are substantially axially coextensive with respect to one another; and
a set of leaflets coupled to the support portion, which can be deployed with the armature in the implantation position, wherein the leaflets define, in the implantation position, a flow duct that is selectably obstructable;
wherein the anchor portion can be deployed to enable anchorage of the cardiac-valve prosthesis at an implantation site.

Abstract
A cardiac-valve prosthesis is adapted for percutaneous implantation. The prosthesis includes an armature adapted for deployment in a radially expanded implantation position, the armature including a support portion and an anchor portion, which are substantially axially coextensive with respect to one another. A set of leaflets is coupled to the support portion. The leaflets can be deployed with the armature in the implantation position. The leaflets define, in the implantation position, a flow duct that is selectably obstructable. The anchor portion can be deployed to enable anchorage of the cardiac-valve prosthesis at an implantation site.

16. An cardiac-valve prosthesis adapted for percutaneous delivery and implantation at an anatomical valve site having a Valsalva sinus, the prosthesis comprising:
-
an armature adapted for delivery in a radially-compressed configuration and deployment in a radially-expanded configuration at the valve site, the armature including a support portion and an anchor portion; and
a set of leaflets coupled to the support portion, which can be deployed with the armature in the radially-expanded configuration, wherein the leaflets define a flow duct that is selectably obstructable;
wherein the anchor portion includes ribs that in the radially-expanded configuration generally conform to the Valsalva sinus to enable anchorage of the cardiac-valve prosthesis at the valve site. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)
