1. A prosthetic mitral valve system comprising:
- a valve assembly comprising an expandable valve frame and an occluder attached to the expandable valve frame;
an anchor assembly comprising an expandable anchor frame that defines a longitudinal axis, the anchor assembly configured to selectively couple with the valve assembly; and
a control wire slidably engaged with the expandable anchor frame at a plurality of engagement locations at a mid-body region along the longitudinal axis of the expandable anchor frame, the control wire being manipulable to increase and decrease a diameter of the expandable anchor frame during implantation of the anchor assembly.

Abstract
Prosthetic heart valves described herein can be deployed using a transcatheter delivery system and technique to interface and anchor in cooperation with the anatomical structures of a native heart valve. Some embodiments of prosthetic mitral valves described herein include an anchor portion that couples the prosthetic mitral valve to the anatomy near the native mitral valve, and a valve portion that is mateable with the anchor portion.

26. A prosthetic mitral valve system comprising:
-
a valve assembly comprising an expandable valve frame and an occluder attached to the expandable valve frame; an anchor assembly comprising an expandable anchor frame that defines a longitudinal axis, the anchor assembly configured to selectively couple with the valve assembly; and a control wire slidably engaged with the expandable anchor frame at a plurality of engagement locations at a mid-body region along the longitudinal axis of the expandable anchor frame, the control wire being manipulable to increase and decrease a diameter of the expandable anchor frame during implantation of the anchor assembly; wherein the control wire is a first control wire, and further comprising a second control wire slidably engaged with the expandable anchor frame at a proximal end region of the expandable anchor frame; wherein the proximal end region of the expandable anchor frame comprises a plurality of arched atrial holding features, and wherein the second control wire is manipulable such that tensioning the second control wire draws the plurality of arched atrial holding features radially inwards towards the longitudinal axis and slackening the second control wire allows the plurality of arched atrial holding features to extend transversely outward in relation to the longitudinal axis; wherein;
the expandable valve frame comprises three valve frame lobes disposed on a proximal end portion of the expandable valve frame;
the expandable anchor frame comprises three anchor frame lobes disposed on a proximal end portion of the expandable anchor frame; and
wherein, while the valve assembly and the anchor assembly are coupled, each valve frame lobe of the three valve frame lobes is aligned with a respective anchor frame lobe of the three anchor frame lobes;wherein the plurality of arched atrial holding features comprises three arched atrial holding features; and wherein each arched atrial holding feature of the three arched atrial holding features is aligned with a corresponding valve frame lobe of the three valve frame lobes and with a corresponding anchor frame lobe of the three anchor frame lobes. - View Dependent Claims (27, 28, 29, 30)
