Two-piece valve prosthesis with anchor stent and valve component
First Claim
1. A modular valve prosthesis including a delivery configuration and a deployed configuration, the modular valve prosthesis comprising:
- an anchor stent including a self-expanding tubular frame member configured to be deployed against walls of the ascending aorta and attachment members extending inwardly from an internal surface of the tubular frame member; and
a valve component separate from the anchor stent in the delivery configuration, the valve component including a valve frame including a distal portion and a proximal portion, wherein in the deployed configuration the distal portion of the valve frame is deployed within the tubular frame member such that the distal portion of the valve frame engages with the attachment members of the tubular frame member, and a prosthetic valve coupled to the proximal portion of the valve frame, wherein in the deployed configuration, the proximal portion of the valve frame is disposed proximal of the anchor stent such that the prosthetic valve is proximal of a proximal end of the anchor stent.

Abstract
A modular valve prosthesis includes an anchor stent and a valve component. The anchor stent includes a self-expanding tubular frame member configured to be deployed in the aorta and a proximal arm component extending from a proximal end of the tubular frame member and configured to be deployed in the sinuses of the aortic valve. The anchor stent further includes attachment members extending from an internal surface of the tubular frame member. The valve component includes a valve frame configured to be deployed within the tubular frame member of the anchor stent such that the valve frame engages with the attachment members of the tubular frame member and a prosthetic valve coupled to the valve frame.
