Abstract

A delivery device for a collapsible prosthetic heart valve, the delivery device comprising an inner shaft, a distal sheath disposed about a portion of the inner shaft and forming a compartment with the inner shaft, the compartment adapted to receive the valve, the inner shaft and the distal sheath being slidable relative to one another, and a handle including a frame, a deployment actuator, a lever, and a hub, each of the deployment actuator, the lever, and the hub being independently capable of opening and closing the compartment, a resheathing lock configured to alert a user of a position of the distal sheath relative to the inner shaft and to impede movement of the distal sheath relative to the frame, and an indicator disposed on the frame and capable of showing an extent of deployment of the valve.
