摘要:
A delivery device for a collapsible heart valve includes an operating handle and a catheter assembly. The operating handle includes a frame defining a movement space therein, a carriage assembly moveable in a longitudinal direction within the movement space, and a coupler having locked and unlocked conditions, the coupler being operatively connected to the carriage assembly for movement therewith. The catheter assembly includes a shaft 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 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.
