摘要：
A delivery device for a collapsible prosthetic heart valve includes an operating handle and a catheter assembly. The operating handle may include a housing defining a movement space therein, a carriage assembly moveable in a longitudinal direction within the movement space, a deployment actuator coupled to the housing and rotatable relative to the housing, and a coupling assembly rotationally fixed to the deployment actuator. The catheter assembly may include a first shaft around which a compartment is defined and a distal sheath operatively connected to the carriage assembly. Movement of the carriage assembly in the longitudinal direction in the movement space may move the distal sheath between the closed condition and the open condition. The coupling assembly may have an engaged position in which rotation of the deployment actuator moves the carriage assembly, and a disengaged position in which rotation of the deployment actuator does not move the carriage assembly.
