First Claim
Patent Images
1. A prosthetic heart valve comprising:
- a radially collapsible and radially expandable frame having a main body, an atrial portion, and at least one ventricular anchor, wherein the main body has an atrial end and a ventricular end, the atrial portion extending radially outwardly relative to the main body and comprising a continuous wire form that extends around the main body, the ventricular anchor extending from the ventricular end of the main body;
wherein the main body and the atrial portion are separate metal components that are coupled to each other via sutures or a fabric member; and
a valve structure having a plurality of leaflets and configured for regulating the flow of blood in one direction through the prosthetic heart valve, wherein the valve structure is supported in the main body of the frame.

Abstract
A prosthetic heart valve includes a collapsible and expandable frame having a main body, an atrial portion, and at least one ventricular anchor. The atrial portion extends radially outwardly relative to the main body and the ventricular anchor extends from a ventricular end of the main body. The main body and the atrial portion are preferably separate metal components that are coupled together via sutures or a fabric member. The prosthetic heart valve also includes a valve structure that is supported in the main body of the frame. The valve structure has a plurality of leaflets for regulating the flow of blood in one direction.
