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.
Claims20
A method of treating a valve disorder in a patient's heart, comprising:
- collapsing a valve prosthesis including a unitary frame and a valve onto a delivery system to place a first portion of the unitary frame longitudinally adjacent to a second portion of the unitary frame, the valve being disposed within the first portion of the unitary frame;
- delivering the delivery system and the valve prosthesis to a heart;
- expanding the valve prosthesis in the heart such that the first portion of the unitary frame moves to be positioned within an interior area of the second portion of the unitary frame;
- and
- withdrawing the delivery system from the heart.
A method of treating a valve disorder in a patient's heart, comprising:
- collapsing a valve prosthesis including a unitary frame and a valve onto a delivery system to place an inner tubular portion of the unitary frame longitudinally adjacent to an outer tubular portion of the unitary frame, the valve being disposed within the inner tubular portion of the unitary frame, wherein the inner tubular portion is longitudinally separated from the outer tubular portion by a plurality of connecting arms that extend between and connect the inner tubular portion with the outer tubular portion;
- delivering the delivery system and the valve prosthesis to a heart;
- expanding the valve prosthesis in the heart such that the inner tubular portion of the unitary frame moves to be positioned within an interior area of the outer tubular portion such that the outer tubular portion surrounds the inner tubular portion;
- and
- withdrawing the delivery system from the heart.
A method of treating a valve disorder in a patient's heart, comprising:
- collapsing a valve prosthesis including a unitary frame and a valve onto a delivery system to place a first tubular portion of the unitary frame longitudinally adjacent to a second tubular portion of the unitary frame along a longitudinal axis of the unitary frame, the valve being disposed within the first tubular portion of the unitary frame, wherein the first tubular portion is longitudinally separated from the second tubular portion by a third portion that extends between and connects the first tubular portion with the second tubular portion;
- delivering the delivery system and the valve prosthesis to a heart;
- expanding the valve prosthesis in the heart such that the first tubular portion of the unitary frame moves to be 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;
- and
- withdrawing the delivery system from the heart.
