1. A delivery system for controlled deployment of a replacement mitral valve, the delivery system comprising:
- a first member configured to at least partially restrain a first end of the replacement mitral valve;
a second member configured to at least partially restrain a second end of the replacement mitral valve having a plurality of anchors extending towards the first end in a deployed position;
a tether configured to at least partially encircle the replacement mitral valve at a base of the anchors and radially restrain at least a portion of the replacement mitral valve after the second member has been removed from the second end of the replacement mitral valve but with the first member still at least partially restraining the first end of the replacement mitral valve; and
a tether retention assembly configured to restrain the tether such that the tether can be tensioned to restrain at least a portion of the replacement mitral valve, the tether retention assembly comprising a C-lock.

Abstract
Devices, systems and methods are described herein a prosthesis for implantation within a lumen or body cavity and delivery devices for delivering the prosthesis to a location for implantation. A delivery system can include a plurality of components which are moveable relative to each other. The delivery system can include a nose cone which can cover at least a first end of the prosthesis, an outer elongate member which can cover at least a second end of the prosthesis, and a tether which can at least partially restrain the prosthesis from deployment.

17. A delivery system for controlled deployment of a replacement mitral valve, the delivery system comprising:
-
a first member configured to at least partially restrain a first end of the replacement mitral valve; a second member configured to at least partially restrain a second end of the replacement mitral valve having a plurality of anchors extending towards the first end in a deployed position; and a tether configured to at least partially encircle the replacement mitral valve at a base of the anchors and radially restrain at least a portion of the replacement mitral valve after the second member has been removed from the second end of the replacement mitral valve but with the first member still at least partially restraining the first end of the replacement mitral valve; wherein the first member comprises a first shaft and the second member comprises a second shaft, the second shaft being positioned over the first shaft and slidable relative to the first shaft; wherein the first member comprises an inner retention ring configured to engage the first end of the replacement mitral valve, the inner retention ring connected to a distal portion of an inner retention shaft, the inner retention shaft being positioned between the first shaft and the second shaft and being slidable relative to the first shaft; and wherein the inner retention ring comprises a cavity at or near a distal end of the inner retention ring and a compressible member received at least partially within the cavity, the compressible member having a compressed diameter and an expanded diameter.
