Abstract
A transcatheter heart valve prosthesis includes an inner frame, an outer frame, and prosthetic valve coupled to the inner frame, an inner skirt coupled to the inner frame, and an outer skirt coupled to the outer frame. The inner frame includes an inflow end and an outflow end. The inner skirt extends from the inflow end of the inner frame and terminals proximal of the outflow end of the inner frame. The outer frame includes a first end and a second end. The first end of the outer frame is coupled to the inner frame between the inflow and outflow ends of the inner frame. The outer skirt extends from the first end of the outer frame and terminates proximal of the second end of the outer frame.
