APPARATUS AND METHODS FOR DELIVERY OF TRANSCATHETER PROSTHETIC VALVES

摘要

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.

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, and the 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.
