Claim:
1. A method for delivering a prosthetic heart valve device for repair or replacement of a native valve a heart of a human patient, the method comprising: positioning a delivery capsule of a catheter within the heart of the patient, the delivery capsule carrying the prosthetic heart valve device; hydraulically moving the delivery capsule in a proximal direction from a containment configuration towards a deployment configuration by delivering fluid through an elongated catheter body and into a fluidically sealed fluid chamber of the delivery capsule, wherein the fluidically sealed chamber is proximal to the prosthetic heart valve device and defined by a space between an inner proximal end surface of the delivery capsule and a proximal head of a piston device located within the delivery capsule, and wherein hydraulically moving the delivery capsule in a proximal direction comprises— allowing the prosthetic heart valve device to radially expand to engage tissue of the heart when the delivery capsule moves from the containment configuration towards the deployment configuration.
