Apparatus and methods for delivery of transcatheter prosthetic valves
First Claim
1. An apparatus, comprising:
- a catheter assembly including a sheath and a hub;
a handle assembly including an actuator, and configured to be removably coupled to the catheter assembly; and
a valve holding tube defining a lumen configured to receive a prosthetic heart valve in a compressed configuration, the valve holding tube configured to be removably coupled to the handle assembly,a distal end portion of the valve holding tube configured to be received within an interior region of the of the hub when the valve holding tube is coupled to the handle assembly, andthe actuator, when actuated, configured to move the handle assembly distally such that the prosthetic heart valve moves distally out of the valve holding tube and out a distal end of the sheath such that the prosthetic heart valve is free to move to a biased expanded configuration.

Abstract
In some embodiments, an apparatus includes a catheter assembly and a handle assembly that can be removably coupled to the catheter assembly. A valve holding tube defines a lumen configured to receive a prosthetic mitral valve in a compressed configuration and can be removably coupled to a distal end portion of the handle assembly. The valve holding tube can be received within a hub of the catheter assembly when coupled to the handle assembly. The actuator when actuated is configured to cause the tensioning unit to travel along a traveler strap of the catheter assembly moving the handle assembly distally such that a distal end of an elongate shaft of the handle assembly moves the prosthetic mitral valve distally out of the valve holding tube and out a distal end of the sheath such that the prosthetic mitral valve is free to move to a biased expanded configuration.

6. A kit, comprising:
-
a valve delivery device including a catheter assembly, a handle assembly removably couplable to the catheter assembly and a valve holding tube removably couplable to the handle assembly, the catheter assembly configured to engage a portion of the handle assembly such that when the valve delivery device is actuated, the handle assembly is moved distally and pushes a prosthetic heart valve out of the valve holding tube and out a distal end of the catheter assembly; and a valve loading device, the valve loading device configured to receive a prosthetic heart valve and move the prosthetic heart valve from a biased expanded configuration to a controlled compressed configuration when disposed within the valve loading device. - View Dependent Claims (7, 8, 9, 10, 11)

12. A method, comprising:
-
inserting a prosthetic heart valve into an interior region of a valve loading device while in a biased expanded configuration; moving the prosthetic heart valve from the biased expanded configuration to a compressed configuration while disposed within the valve loading device; transferring the prosthetic heart valve while in the compressed configuration from the valve loading device to a valve holding tube; after transferring the prosthetic heart valve to the valve holding tube, coupling the valve holding tube with the prosthetic heart valve disposed therein in the compressed configuration to a distal end portion of a handle assembly; and
inserting a sheath of a catheter assembly into a heart. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
