Abstract: Delivery devices and methods for delivering a prosthetic heart valve. The delivery device includes an inner shaft assembly with a valve retainer, an outer shaft assembly, a handle assembly and an axial force adjustment assembly. The outer shaft assembly includes a capsule containing the prosthetic valve in a loaded state. The handle assembly is coupled to a proximal region of the outer shaft assembly. The axial force adjustment assembly connects a proximal section of the inner shaft assembly to the handle assembly, and is configured to selectively move the proximal section relative to the handle assembly. The axial force adjustment assembly can include an actuator member and a driver member. The driver member directly interfaces with the inner shaft assembly, and a force applied to the actuator member is transferred onto the proximal section via the driver member. A sensor for sensing tension and/or compression in the inner shaft assembly can be provided.
