摘要:
A valve catheter is advanced through a patient's vasculature while a prosthetic heart valve is attached to flexible extensions along a distal end thereof. The valve catheter is advanced through a tubular sleeve for exposing the prosthetic heart valve and allowing the prosthetic heart valve to self-expand while the extensions remain attached to the prosthetic heart valve. A release mechanism on a handle portion is actuated for releasing the prosthetic heart valve from the extensions, thereby implanting the prosthetic heart in a native heart valve. If the operator is not satisfied with the initial expansion, the prosthetic heart valve may be reoriented before release from the extensions by retracting the prosthetic heart valve back into the tubular sleeve, adjusting the orientation of the prosthetic heart valve and then re-advancing the valve catheter from the tubular sleeve for allowing the prosthetic heart valve to re-self-expand at a more desirable location.
