1. A method of deploying an expandable prosthetic mitral valve device in a subject, said method comprising:
- deploying a first component of said prosthetic mitral valve device in a left atrium, the first component including an annulus part;
deploying a second component of said prosthetic mitral valve in a left ventricle, the second component including a ventricle part; and
approximating said first and said second components so that one or more leaflets of a native mitral valve are trapped between said first and said second components,the method being performed using apparatus comprising;
the prosthetic mitral valve device for fitted insertion to a native mitral valve annulus of a heart of the subject, the prosthetic mitral valve comprising the annulus part and the ventricle part; and
a deployment device for deployment of the prosthetic mitral valve device, the deployment device comprising;
a delivery housing configured to house the annulus part and the ventricle part of the prosthetic mitral valve device in radially-compact configurations, wherein;
the annulus part and the ventricle part are each configured to be radially expandable subsequent to release from the delivery housing, andthe expanded ventricle part and the expanded annulus part are shaped to mate in a deployed mating configuration, such that there is a gap between the ventricle part and the annulus part, the gap being configured to accommodate one or more leaflets of the native mitral valve; and
an approximator that is configured, while attached to both the annulus part and the ventricle part;
to force each of the annulus part and the ventricle part toward the other from initially separated positions into the mating configuration, such that the one or more leaflets of the native mitral valve are held within the gap between the ventricle part and the annulus part; and
to secure the annulus part and the ventricle part in the mating configuration.
