摘要：
A delivery device (10) for a collapsible heart valve includes an operating handle (20) and a catheter assembly (16). The operating handle includes a frame (30) defining a movement space therein, a carriage assembly (40) moveable in a longitudinal direction within the movement space, and a coupler (60) having locked and unlocked conditions, the coupler being operatively connected to the carriage assembly for movement therewith. The catheter assembly includes a shaft (26) around which a valve receiving compartment is defined, the shaft being operatively connected to one of the frame or the carriage assembly, and a distal sheath (24) operatively connected to the carriage assembly for movement therewith between a closed condition adapted to maintain the valve in the compartment and an open condition adapted to fully deploy the valve.
