1. A device to occlude and electrically isolate a body lumen comprising an implantable occlusion apparatus (3) operably attached to an elongated catheter member (4) configured for transluminal delivery and deployment of the occlusion apparatus in the body lumen, the occlusion apparatus comprising:
a radially self-expansible element (5) comprising a wire mesh cage detachably attached to the elongated catheter member, and adjustable between a contracted orientation suitable for transluminal delivery and a deployed orientation configured to occlude the body lumen; and
an energy delivery element (6, 14, 21) comprising an array of electrodes configured to deliver energy to surrounding tissue to ablate the tissue,
in which the energy delivery element is associated with the radially expansible element and configured to be left in-situ in the body lumen when the catheter member is detached from the occlusion apparatus,
in which the array of electrodes is configured to generate an electrical map or profile of an ablation zone and the surrounding tissue electrical impedance measurements to characterize the electrical properties of the tissue as a measurement and confirmation of ablation effectiveness.
