Staged development devices and methods for transcatheter heart valve delivery
First Claim
1. A delivery device for a collapsible prosthetic heart valve, the delivery device comprising:
- an operating handle, including;
a frame;
a carriage assembly moveable in a longitudinal direction relative to the frame;
a coupler; and
a deployment actuator constrained relative to the coupler in the longitudinal direction,the coupler having a locked condition in which the coupler is connected to the frame in a fixed position and in which rotation of the deployment actuator moves the carriage assembly in the longitudinal direction relative to the coupler, and an unlocked condition in which the coupler, the deployment actuator, and the carriage assembly are movable together in the longitudinal direction, the coupler being operatively connected to the carriage assembly for movement therewith; and
a catheter assembly, including;
a first shaft around which a compartment is defined, the first shaft being operatively connected to the frame, the compartment being adapted to receive the valve in an assembled condition; and
a distal sheath operatively connected to the carriage assembly, the distal sheath being moveable between a closed condition and an open condition,wherein movement of the carriage assembly in the longitudinal direction moves the distal sheath between the closed condition and the open condition.

Abstract
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.

19. A method of delivering a collapsible prosthetic heart valve in a patient, the method comprising:
-
providing a delivery device having a catheter assembly and an operating handle, the catheter assembly including a compartment adapted to receive the valve in an assembled condition, the operating handle including a frame, a carriage assembly moveable in first and second opposite longitudinal directions, a coupler, and a deployment actuator constrained relative to the coupler in the longitudinal directions, the coupler operatively coupling the carriage assembly to the frame; loading the valve into the compartment of the catheter assembly, the compartment and the valve being covered by a distal sheath of the catheter assembly; rotating the deployment actuator to move the carriage assembly of the operating handle relative to the coupler and the frame in a first longitudinal direction, while the coupler is in a locked condition in which the coupler is connected to the frame in a fixed position; and unlocking the coupler from the frame and translating the coupler together with the carriage assembly to continue movement of the carriage assembly in the first longitudinal direction. - View Dependent Claims (20)
