1. An implantable heart valve device, comprising:
- a tubular frame having a proximal end, a distal end and a central lumen extending therethrough;
the frame comprising at least a first pair of adjacent struts joined at a proximally facing apex, and at least a second pair of adjacent struts joined at a distally facing apex;
a plurality of distally facing anchors coupled with the frame and configured to embed into tissue surrounding a native mitral valve;
a valve coupled with the frame to regulate blood flow through the central lumen; and
a moveable restraint coupled with the frame and configured to restrain the frame at a desired width; and
an annular seal carried by the frame, for inhibiting perivalvular leaks.

Abstract
Features for a heart valve device are described. The device may include a frame with anchors configured to secure the device to tissue. The frame may include a flared end or skirt for additional securement of the implanted device. The device may include a seal such as a barrier and/or cuff for preventing leakage. The device may contract for endovascular delivery of the device to the heart and expand for securement within the heart, such as the within the native mitral valve annulus. The device may include a replacement valve. The valve may have leaflets configured to re-direct blood flow along a primary flow axis.
