Abstract
A delivery apparatus can include a handle portion and at least one rotatable drive shaft. The handle portion has an actuation mechanism. The actuation mechanism includes a motor and one or more actuators. The rotatable drive shaft has a proximal end portion and a distal end portion. The proximal end portion is coupled to the motor, and the distal end portion is configured to be releasably coupled to a prosthetic heart valve. The actuation mechanism is configured to control and monitor expansion of the prosthetic heart valve. The handle is configured for actuating the actuation mechanism, tracking a response of native tissue when the prosthetic heart valve is in contact with the native tissue, and stopping expansion of the prosthetic heart valve once a rate of change of expansion of the prosthetic heart valve declines below a threshold.
