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.
