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.

A method of implanting a prosthetic valve at a location of a native aortic valve comprising:
- advancing an anchor stent in a radially compressed configuration into an ascending aorta, wherein the anchor stent includes a proximal arm component comprising a plurality of arms and each of the plurality of arms comprises a wire loop with a first end of the wire coupled to the first end of the tubular frame member, the wire extending away from the first end of the tubular frame member and bending back to a second end of the wire coupled to the first end of the tubular frame member spaced from the first end of the wire;
- deploying the anchor stent at a location within the ascending aorta such that a tubular frame member of the anchor stent expands from the radially compressed configuration to a radially expanded configuration engaging an inner wall surface the ascending aorta and the proximal arm component is deployed in sinuses of the aortic valve;
- separately advancing a valve component in a radially compressed configuration past the deployed anchor stent to a location of the native aortic valve, wherein the valve component comprises a valve frame and a prosthetic valve coupled to the valve frame;
- and
- deploying the valve component at the native aortic valve such that the valve frame expands from the radially compressed configuration to a radially expanded configuration with a first portion of the valve frame engaging an annulus of the native aortic valve and a second portion the valve frame disposed within the tubular frame member of the anchor stent.

- deploying the anchor stent at a location within the ascending aorta such that a tubular frame member of the anchor stent expands from the radially compressed configuration to a radially expanded configuration engaging an inner wall surface the ascending aorta;
- separately advancing a valve component in a radially compressed configuration past the deployed anchor stent to a location of the native aortic valve, wherein the valve component comprises a valve frame and a prosthetic valve coupled to the valve frame;
- and
- deploying the valve component at the native aortic valve such that the valve frame expands from the radially compressed configuration to a radially expanded configuration with a first portion of the valve frame engaging an annulus of the native aortic valve and a second portion the valve frame disposed within the tubular frame member of the anchor stent;
- wherein the anchor stent further comprises attachment members extending radially inwardly from the tubular frame member, wherein deploying the valve component comprises the second portion of the valve frame engaging the attachment members.
