1. A method for repairing a heart valve of a patient, the method comprising:

  • manipulating a heart valve replacement system in a delivery state to deliver a prosthetic heart valve of the system to a target site, the system further including an inner shaft assembly, a delivery sheath assembly including a capsule terminating at a distal end, and a balloon, the delivery state including the capsule maintaining the prosthetic heart valve in a collapsed condition over the inner shaft assembly, and the balloon in a deflated arrangement radially between the prosthetic heart valve and the capsule;

    exposing at least a portion of the balloon distal the distal end;

    inflating the exposed portion of the balloon;

    positioning at least a portion of the prosthetic heart valve distal the distal end, wherein the inflated balloon is disposed between the at least a portion of the prosthetic heart valve and anatomy of the target site, including the inflated balloon simultaneously in direct physical contact with both the prosthetic heart valve and the anatomy of the target site; and

    deploying the prosthetic heart valve from the inner shaft assembly to the target site.
