摘要：
A delivery device (10) for a collapsible prosthetic valve, the delivery device comprising: an operating handle (20), which includes: a housing (30) defining a movement space (34) therein； a carriage assembly (40) movable in a longitudinal direction within the movement space； a deployment actuator (21) coupled to the housing and rotating in relation to the housing； and a coupling assembly (60) fixed in rotation to the deployment actuator, the coupling assembly having a coupled position in which the rotation of the deployment actuator moves the carriage assembly in the longitudinal direction, and an uncoupled position in which the rotation of the deployment actuator does not move the carriage assembly in the longitudinal direction； and a catheter assembly (16), which includes: a first rod (26) around which a compartment (23) is defined, the first rod being functionally connected to the housing, the compartment being adapted to receive the valve in an assembled state ； and a distal sheath (24) functionally connected to the carriage assembly, the movable distal sheath being between a closed state that covers the compartment and an open state that discovers the compartment for valve deployment, in which the carriage assembly movement in the longitudinal direction, within the movement space, it moves the distal sheath between the closed state and the open state, and in which the carriage assembly includes a threaded bar (36) extending from a body (41) of the carriage assembly and towards threaded coupling with the coupling assembly, characterized in that the coupling assembly includes a split nut (64) having a plurality of threaded nut parts (64a, 64b), each of the nut parts being slit linearly slid in the direction of moving away from others and moving away from the threaded rod, the split nut having a coupled position in which the threads of the split nut portions are n coupled with the threaded rod and an uncoupled position in which the threads of the split nut parts a
