1. A valve prosthesis comprising:
- a valve body; and
a unitary frame includinga first tubular portion connected to the valve body, anda second tubular portion configured to contact and conform to a native valve annulus in situ,the unitary frame havinga delivery configuration in which the first tubular portion is positioned in series with the second tubular portion along a longitudinal axis of the unitary frame and the first tubular portion is longitudinally adjacent to the second tubular portion, andan expanded configuration in which the first tubular portion is positioned within an interior area of the second tubular portion, such that the second tubular portion surrounds the first tubular portion and both of the first tubular portion and the second tubular portion extend parallel to the longitudinal axis of the unitary frame.

Abstract
Heart valve prostheses are provided for replacing a cardiac valve. The heart valve prosthesis includes a self-expanding frame including a first portion and a second portion. In the collapsed configuration, the first portion is positioned adjacent to the second portion. In the expanded configuration, the first portion moves to be positioned within an interior area of the second portion.

5. A valve prosthesis comprising:
-
a valve body; and a unitary frame including a first tubular portion connected to the valve body, a second tubular portion configured to contact and conform to a native valve annulus in situ, and a third portion that connects the first tubular portion with the second tubular portion, wherein the unitary frame includes a delivery configuration in which the first tubular portion is positioned in series with the second tubular portion along a longitudinal axis of the unitary frame and the first tubular portion is longitudinally separated from the second tubular portion by the third portion, and wherein the unitary frame includes an expanded configuration in which the first tubular portion is positioned within an interior area of the second tubular portion, such that the second tubular portion surrounds the first tubular portion and both of the first tubular portion and the second tubular portion extend parallel to the longitudinal axis of the unitary frame with the third portion at least partially radially extending therebetween. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14)

15. A valve prosthesis comprising:
-
a valve body; and a unitary frame including an inner tubular portion connected to the valve body, the inner tubular portion defining a plurality of cells, an outer tubular portion configured to contact and conform to a native valve annulus in situ, the outer tubular portion defining a plurality of cells, and a plurality of connecting arms extending between and connecting the inner tubular portion and the outer tubular portion, wherein the unitary frame includes a delivery configuration in which the inner tubular portion is positioned in series with the outer tubular portion along a longitudinal axis of the unitary frame and the inner tubular portion is longitudinally separated from the outer tubular portion by the plurality of connecting arms, and wherein the unitary frame includes an expanded configuration in which the inner tubular portion is positioned at least partially within an interior area of the outer tubular portion such that the outer tubular portion surrounds the inner tubular portion and both of the inner tubular portion and the outer tubular portion extend parallel to the longitudinal axis of the unitary frame with the plurality of connecting arms at least partially radially extending therebetween. - View Dependent Claims (16, 17, 18, 19, 20)
