APPARATUS AND METHODS FOR DELIVERY, REPOSITIONING, AND RETRIEVAL OF TRANSCATHETER PROSTHETIC VALVES
First Claim
1. An apparatus, comprising:
- a catheter assembly including an elongate sheath defining a delivery lumen;
a valve holding tube defining an interior region configured to receive therein a prosthetic heart valve, the valve holding tube having a distal end portion configured to be releasably coupled to the hub of the catheter assembly; and
a handle assembly including a housing and a delivery rod, a distal end portion of the housing configured to be releasably coupled to a proximal end portion of the valve holding tube such that a distal end of the delivery rod is disposed within the interior region of the valve holding tube proximally of the prosthetic heart valve,the delivery rod configured to be actuated to move distally relative to the housing to move a prosthetic heart valve disposed within the valve holding tube out of the valve holding tube and distally within the elongate sheath of the catheter assembly,the catheter assembly configured to be actuated to move proximally relative to the housing such that the prosthetic valve is disposed outside of the lumen of the elongate sheath.

Abstract
Apparatus and methods are described herein for use in the delivery and deployment of a prosthetic mitral valve into a heart. In some embodiments, an apparatus includes a catheter assembly, a valve holding tube and a handle assembly. The valve holding tube is releasably couplable to a proximal end portion of the catheter assembly and to a distal end portion of the handle assembly. The handle assembly includes a housing and a delivery rod. The delivery rod is configured to be actuated to move distally relative to the housing to move a prosthetic heart valve disposed within the valve holding tube out of the valve holding tube and distally within a lumen of the elongate sheath of the catheter assembly. The catheter assembly is configured to be actuated to move proximally relative to the housing such that the prosthetic valve is disposed outside of the lumen of the elongate sheath.

27. A method, comprising:
-
coupling a valve holding tube to a distal end portion of a handle assembly of valve delivery device, the valve holding tube having a prosthetic heart valve disposed therein in a collapsed configuration; coupling the valve holding tube to a hub of a catheter assembly of the valve delivery device such that the valve holding tube is disposed between the catheter assembly and the handle assembly; inserting distal end portion of the catheter assembly into a heart and extend into a left atrium of heart; actuating a first actuator to move the prosthetic heart valve distally into a distal end portion of a lumen defined by a sheath of the catheter assembly; and after the actuating the first actuator, actuating a second actuator to move the sheath proximally relative to the handle assembly such that prosthetic heart valve is disposed outside a distal end of the sheath and within the left atrium of the heart. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34)
