Abstract
A delivery device for a collapsible heart valve includes an operating handle, including a frame defining a movement space therein, a carriage assembly moveable within the movement space, and a first resheathing lock having a locked position and an unlocked position. The delivery device further includes a catheter assembly, including a first shaft around which a valve-receiving compartment is defined, the first shaft being fixedly connected to one of the frame or the carriage assembly, and a distal sheath operatively connected to the carriage assembly. The distal sheath is moveable between a closed condition adapted to maintain the valve in the compartment and an open condition adapted to fully deploy the valve. With the resheathing lock in the locked position, the distal sheath is unable to move to the open condition to fully deploy the valve.
