## Abstract

An endovascularly deployed prosthetic includes a portion for being positioned within an ascending aorta. The prosthesis includes a replacement aortic valve on a proximal end thereof. The prosthesis includes an increased diameter portion that seals against the aorta at a more distal portion, and a pair of conduits extend from the increased diameter portion to the coronaries for fluidly coupling the coronaries to the prosthesis.

## Claims

### Claim 1

A transcatheter heart valve assembly comprising:
an inner frame comprising a first graft covering about a prosthetic heart valve, wherein the first graft covering extends proximal the prosthetic heart valve for providing sealing to the prosthetic heart valve;
an outer frame formed from a metallic material and defining an open cell configuration, and being secured to the first graft covering by a plurality of stitches, the outer frame being positioned at least partially radially outwardly of the inner frame; and
a sealing material positioned externally to the outer frame and configured for providing sealing between the outer frame and a patient's anatomical wall to prevent paravalvular leaks,
wherein the sealing material includes a plurality of radially extending fibers, wherein at least some of the radially extending fibers are fibers that extend outwardly of the outer frame;
wherein the first graft covering is made of a polymer,
wherein at least some other of the radially extending fibers engage the first graft covering at a proximal end of the heart valve assembly to seal an inflow end portion thereof,
wherein a second graft covering extends about a distal end of the heart valve assembly to seal an outflow end portion thereof.

### Claim 2 (depends on 1)

The transcatheter heart valve assembly according to claim 1, wherein the first graft covering extends to the inflow end portion of the outer frame, wherein, stitching extending between the first graft covering through the inner frame secures the first graft covering to the inflow end portion of the outer frame.

### Claim 3 (depends on 1)

The transcatheter heart valve assembly according to claim 1, wherein the transcatheter heart valve assembly is configured to replace a native mitral valve.
