Apparatus and methods for delivery of transcatheter prosthetic valves
First Claim
1. An apparatus, comprising:
- a catheter assembly including a sheath, a hub and a traveler strap;
a handle assembly including an actuator, a tensioning unit coupled to the actuator, and an elongate shaft, the handle assembly configured to be removably coupled to the catheter assembly; and
a valve holding tube defining a lumen configured to receive a prosthetic mitral valve in a compressed configuration, the valve holding tube configured to be removably coupled to a distal end portion of the elongate shaft of 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 elongate shaft of the handle assembly, andthe actuator, when actuated, configured to cause the tensioning unit of the handle assembly to travel along the traveler strap and move the handle assembly distally such that a distal end of the elongate shaft 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.

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.

9. A method, comprising:
-
coupling a valve holding tube to a distal end portion of a handle assembly, the valve holding tube having a prosthetic mitral valve disposed therein in a compressed configuration; inserting a sheath of a catheter assembly into a heart and extend to the left atrium; after the inserting the sheath of the catheter assembly, inserting a distal end portion of the valve holding tube into a hub of the catheter assembly; and actuating the handle assembly such that the handle assembly is moved distally and a distal end of the handle assembly moves the prosthetic mitral valve distally out of the valve holding tube and out a distal end of the sheath and into the left atrium of the heart, the prosthetic mitral valve configured to move to a biased expanded configuration when uncompressed by the valve holding tube and the sheath. - View Dependent Claims (10, 11, 12, 13)

14. 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 including a traveler strap configured to engage a tensioning unit of the handle assembly such that when the valve delivery device is actuated, the handle assembly is moved distally along the traveler strap and pushes a prosthetic mitral 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 mitral valve and move the prosthetic mitral valve from a biased expanded configuration to a controlled compressed configuration within the valve loading device. - View Dependent Claims (15, 16, 17, 18, 19)
