Abstract
A method for delivering and implanting a prosthetic heart valve in a native aortic valve includes collapsing a prosthetic heart valve to a contracted configuration while the prosthetic heart valve is coupled to a mechanical deployment mechanism. A catheter shaft is advanced over a guidewire and through a femoral artery with the deployment mechanism and prosthetic heart valve disposed along a distal end portion thereof. The prosthetic heart valve is permitted to self-expand to an initial expanded configuration. The deployment mechanism is actuated from an operating handle to expand the prosthetic heart valve from the initial expanded configuration to a final expanded configuration. The prosthetic heart valve is locked in the final expanded configuration via a mechanical locking device located on the prosthetic heart valve.
