1. A delivery apparatus, comprising:
- a handle portion having an actuation mechanism and a display, wherein the actuation mechanism includes a motor and one or more actuators; and
at least one rotatable drive shaft having a proximal end portion and a distal end portion, wherein 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,wherein the actuation mechanism is configured to control and monitor expansion of the prosthetic heart valve, andwherein the display is configured to display a diameter of the prosthetic heart valve as a circle that has a diameter that is the same as the diameter of the prosthetic heart valve.

Abstract
A delivery apparatus comprises a handle portion and at least one rotatable drive shaft. The handle portion has an actuation mechanism and a display. 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, and the display is configured to display a diameter of the prosthetic heart valve.

13. A method for implanting a prosthetic heart valve, comprising:
-
advancing a prosthetic heart valve into a patient'"'"'s vasculature with a delivery apparatus; positioning the prosthetic heart valve at an implantation location; expanding the prosthetic heart valve from a contracted state to an expanded state with the delivery apparatus; and displaying a diameter of the prosthetic heart valve on a display during the act of expanding; displaying a radial force imparted to native heart valve tissue by the prosthetic heart valve on the display during the act of expanding; and providing a warning when the radial force is less than a force necessary to prevent embolization of the prosthetic heart valve. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A delivery apparatus, comprising:
-
a handle portion having an actuation mechanism, wherein the actuation mechanism includes a motor and one or more actuators; and at least one rotatable drive shaft having a proximal end portion and a distal end portion, wherein 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, wherein the actuation mechanism includes electronic control circuitry configured to expand the prosthetic heart valve from a fully contracted diameter to a pre-defined diameter and to automatically stop expansion at the pre-defined diameter based on a first actuation by a user. - View Dependent Claims (24, 25)
