Embodiment Construction

[0068] Described herein are devices and methods for delivering and deploying a prosthetic heart valve (eg, a prosthetic mitral valve) into the heart. In some embodiments, a delivery device as described herein can be used to deploy and reposition a prosthetic heart valve. In some embodiments, a delivery device as described herein may include a two-stage controlled deployment mechanism for allowing precise valve deployment. A delivery device as described herein may comprise a single 34Fr all-in-one system capable of accommodating various valve sizes. In some embodiments, described herein are repositioning and retrieval devices that can be used to reposition and / or retrieve a deployed prosthetic heart valve. The repositioning and retracting device may include a two-stage controlled capture of a prosthetic valve implanted in the heart to reposition and / or remove / retrieve the prosthetic valve.

[0069] Although some embodiments are described herein with reference to a prosthetic ...

Abstract

Devices and methods for delivering and deploying a prosthetic mitral valve into the heart are described herein. In some embodiments, a device includes a catheter assembly / valve retention tube and a handle assembly. A valve retention tube is releasably coupled to the proximal portion of the catheter assembly and the distal 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 retaining tube out of the valve retaining tube and distally within the lumen of the elongated 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 the lumen of the elongate sheath.
