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. ## Claims ### Claim 1 A valve prosthesis comprising: a main frame including a first section, a second section, and a third section; a valve body connected to the frame; and a support frame including a first engagement arm and a second engagement arm connected to the main frame in the first section, wherein the first engagement arm is connected to the main frame in the first section at a first point and a second point, wherein the second engagement arm is connected to the main frame in the first section at a third point and a fourth point, and wherein the first engagement arm and the second engagement arm include a radial portion where the respective engagement arms extend in the radial direction. ### Claim 2 (depends on 1) The valve prosthesis of claim 1, wherein a length of the first engagement arm in the longitudinal direction is equal to a length of the second engagement arm in the longitudinal direction. ### Claim 3 (depends on 1) The valve prosthesis of claim 1, wherein a length of the first engagement arm in the longitudinal direction is greater than a length of the second engagement arm in the longitudinal direction. ### Claim 4 (depends on 1) The valve prosthesis of claim 1, wherein the first point is equal to the fourth point, and wherein the second point is equal to the third point. ### Claim 5 (depends on 1) The valve prosthesis of claim 1, wherein the first point, second point, third point, and fourth point are distinct. ### Claim 6 (depends on 1) The valve prosthesis of claim 1, wherein the first engagement arm is integral to the second engagement arm and forms a continuous structure. ### Claim 7 (depends on 6) The valve prosthesis of claim 6, further comprising: a first connecting segment joining the first engagement arm at the first point to the second engagement arm at the fourth point; and a second connecting segment joining the first engagement arm at the second point to the second engagement arm at the third point. ### Claim 8 (depends on 7) The valve prosthesis of claim 7, further comprising: a biocompatible material covering the first engagement arm, the second engagement arm, the first connecting segment, and the second connecting segment. ### Claim 9 (depends on 7) The valve prosthesis of claim 7, further comprising: the first and second connecting segments having a radially repeating cell pattern. ### Claim 10 (depends on 9) The valve prosthesis of claim 9, wherein the radially repeating cell pattern of the first and second connecting segments is identical to the radially repeating cell pattern of the first section. ### Claim 11 (depends on 9) The valve prosthesis of claim 9, further comprising: a biocompatible material covering the first engagement arm, the second engagement arm, the first connecting segment, and the second connecting segment. ### Claim 12 (depends on 1) The valve prosthesis of claim 1, wherein the first engagement arm is distinct from the second engagement arm. ### Claim 13 (depends on 1) The valve prosthesis of claim 1, wherein the first engagement arm and the second engagement arm extend outward from the main frame to form a gap between a free end of the first engagement arm and the main frame and between a free end of the second engagement arm and the main frame. ### Claim 14 (depends on 1) The valve prosthesis of claim 1, wherein a free end of the first engagement arm and a free end of the second engagement arm conform to an exterior surface of the main frame. ### Claim 15 (depends on 1) The valve prosthesis of claim 1, wherein the first engagement arm and the second engagement arm are integral to the main frame. ### Claim 16 A valve prosthesis comprising: a valve body; and a frame including: a first portion connected to the valve body, and a second portion adapted for implantation in a native valve annulus; the frame having a delivery configuration where the first portion is longitudinally adjacent to the second portion and an expanded configuration where the first portion is positioned within an interior area of the second portion. ### Claim 17 (depends on 16) The valve prosthesis of claim 16, wherein in the expanded configuration, the entire first portion is positioned within the interior area of the second portion. ### Claim 18 (depends on 16) The valve prosthesis of claim 16, wherein the first portion and the second portion are integrally formed and are connected by a third portion. ### Claim 19 (depends on 16) The valve prosthesis of claim 16, further comprising engagement arms configured to engage native valve leaflets, the engagement arms being connected to the frame in the first portion. ### Claim 20 A method of treating a valve disorder in a patient's heart, comprising: collapsing a valve prosthesis including a frame onto a delivery system to place a first portion of the frame adjacent a second portion of the frame; delivering the delivery system and valve prosthesis to a heart; expanding the valve prosthesis in the heart such that the first portion of the frame moves to be positioned within an interior area of the second portion of the frame; and withdrawing the delivery system from the heart.
