    • In one embodiment, the present invention provides a prosthesis that can be implanted within a heart to at least partially block gaps that may be present between the two mitral valve leaflets. In one preferred embodiment, the prosthesis includes an anchoring ring that expands within the left atrium to anchor the prosthesis and a pocket member fixed to the anchoring ring. The pocket member is positioned within the mitral valve, between the leaflets so that an open end of the pocket member is positioned within the left ventricle. When the mitral valve is open, blood flows past the pocket member, maintaining the pocket member in a collapsed state. When the mitral valve closes, the backpressure of the blood pushes into the pocket member, expanding the pocket member to an inflated shape. The mitral valve leaflets contact the expanded pocket member, allowing the prosthesis to block at least a portion of the openings between the leaflets, thereby minimizing regurgitated blood flow into the left atrium.
    • 在一个实施例中,本发明提供了一种假体,其可植入心脏内以至少部分阻止可能存在于两个二尖瓣瓣叶之间的间隙。 在一个优选实施例中,假体包括锚定环,其在左心房内扩张以锚定假体和固定到锚定环的口袋构件。 口袋构件位于二尖瓣之间,在小叶之间,使得口袋构件的开口端位于左心室内。 当二尖瓣打开时,血液流过口袋构件,保持口袋构件处于折叠状态。 当二尖瓣关闭时,血液的背压推入口袋构件,将口袋构件膨胀成膨胀的形状。 二尖瓣小叶接触膨胀的口袋构件,允许假体阻挡小叶之间的至少一部分开口,从而最小化进入左心房的反流血液。
