Claim 0:
1. A transcatheter atrio-ventricular valve prosthesis disposable in a connection channel of a native heart valve between atrial and ventricular chambers of a heart having a circumferential connection channel wall structure, the transcatheter atrio-ventricular valve prosthesis comprising:
an inner device including an inflow end and an outflow end and comprising a support structure that is radially expandable, the support structure including on an outer periphery thereof a compressible structure that is configured to be compressed into a compressed state when the prosthesis is deployed in the connection channel of the native heart valve;
a valve disposed within and attached to the inner device; and
an outer device comprising a plurality of arms coupled to an outflow end of the inner device, the plurality of arms extending from the outflow end towards the inflow end of the inner device, each arm of the plurality of arms having a single axial end that is connected to the support structure and a free end, the plurality of arms being configured to:
receive a portion of the circumferential connection channel wall structure, and clamp the portion of the circumferential connection channel wall structure in a groove formed between the plurality of arms and the inner device by compressing the compressible structure into a compressed state when the prosthesis is deployed in the connection channel of the native heart valve, and
radially wrap free ends of native valve leaflets of the connection channel wall structure.
