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 housing defining a movement space therein;
a carriage assembly moveable in a longitudinal direction within the movement space and including a body and a toothed rack extending from the body;
a deployment actuator coupled to the housing and rotatable relative to the housing, the deployment actuator including a knob rotatable about a central axis that extends transverse to the longitudinal direction; and
a coupling assembly configured to rotate with the deployment actuator, the coupling assembly having an engaged position with the toothed rack in which rotation of the deployment actuator moves the carriage assembly in the longitudinal direction, and a disengaged position from the toothed rack in which rotation of the deployment actuator does not move the carriage assembly in the longitudinal direction; and
a catheter assembly, including;
a first shaft around which a compartment is defined, the first shaft being operatively connected to the housing, 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 covering the compartment and an open condition uncovering the compartment for deployment of the valve,wherein movement of the carriage assembly in the longitudinal direction in the movement space moves the distal sheath between the closed condition and the open condition.

Abstract
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.

13. 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 housing defining a movement space therein, a carriage assembly moveable in first and second longitudinal directions within the movement space and including a body and a toothed rack extending from the body, a deployment actuator coupled to the housing and rotatable relative to the housing the deployment actuator including a knob rotatable about a central axis that extends transverse to the first and second longitudinal directions, and a coupling assembly configured to rotate with the coupling assembly having an engaged position with the toothed rack in which rotation of the deployment actuator moves the carriage assembly in the longitudinal direction, and a disengaged position from the toothed rack in which rotation of the deployment actuator does not move the carriage assembly in the longitudinal direction the deployment actuator; loading the valve into the compartment of the catheter assembly and covering the compartment and the valve with a distal sheath of the catheter assembly; inserting the catheter assembly into the patient so that the valve is positioned at a target location within the patient; partially deploying the valve by moving the carriage assembly of the operating handle in the first longitudinal direction along a first portion of the movement space; and fully deploying the valve by continuing movement of the carriage assembly in the first longitudinal direction along a second portion of the movement space. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
