Abstract
An assembly includes a prosthetic heart valve and a delivery apparatus. The prosthetic heart valve has a plurality of pivotably connected struts and one or more adjustable elements rotatably coupled to the struts. Rotating the adjustable elements in a first direction relative to the struts radially expands the prosthetic heart valve. Rotating the adjustable elements in a second direction relative to the struts radially contracts the prosthetic heart valve. The delivery apparatus includes one or more motors, one or more drive wires coupled to the motors, and a memory. The drive wires are coupled to the adjustable elements of the prosthetic heart valve. The motors are configured to rotate the drive wires and the adjustable elements to expand and contract the prosthetic heart valve. The memory is configured for storing one or more characteristics of the motors, the drive wires, or the prosthetic heart valve.
