1. A method for implanting a heart valve prosthesis into a patient'"'"'s heart, the method comprising:

  • inserting the heart valve prosthesis into a barrel of an implanter, such that the prosthesis has a reduced cross-sectional dimension relative to a fully expanded cross-sectional dimension of the prosthesis;

    opening a patient'"'"'s chest;

    creating an opening in tissue to provides a substantially direct path to a desired implantation site in the patient'"'"'s heart;

    passing a length of the cylindrical enclosure through the opening to position an end of the implanter near the desired implantation site in the patient;

    discharging the heart valve prosthesis from the barrel of the implanter; and

    expanding the heart valve prosthesis at the desired position from the reduced cross-sectional dimension toward the expanded cross-sectional dimension, such that an exterior portion of the heart valve prosthesis engages adjacent tissue to mitigate movement of the prosthesis relative to the adjacent tissue.
