1. A method of implanting a prosthetic sealing device at a native mitral valve of a heart, the method comprising:

  • advancing a delivery catheter to a native mitral valve region of a heart from a left atrium of the heart, the delivery catheter housing the prosthetic sealing device in a radially compressed configuration;

    advancing the prosthetic sealing device distally relative to the delivery catheter such that an anchor of the prosthetic sealing device moves out of the catheter and forms a leaflet-receiving gap between an end portion of the anchor and the delivery catheter;

    positioning either a posterior or an anterior mitral valve leaflet in the gap; and

    advancing a radially compressed body of the prosthetic sealing device out of the delivery catheter such that the body self-expands radially toward the end portion of the anchor, reducing the gap, and capturing the leaflet between the body and the end portion of the anchor, wherein the body is configured to prevent the flow of blood through the body during systole and during diastole;

    wherein a non-captured one of the anterior and posterior leaflets is not secured to the prosthetic sealing device when the prosthetic sealing device is implanted for intended use at the native mitral valve.
