Claims20
A medical device comprising:
- a deployable applicator head comprising an expandable outer balloon having a plurality of perforations and an expandable inner balloon configured to maintain separation between an exterior surface of the inner balloon and an interior surface of the outer balloon thereby forming an interior chamber;
- and
- a plurality of conductive wires disposed within the interior chamber and configured to conduct energy to be carried by a conductive fluid passing through one or more of the plurality of perforations, each of the plurality of conductive wires having a substantially constant cross-section along its length.
A medical device comprising:
- a deployable applicator head comprising a self-expandable mesh body;
- an electrical element configured to deliver an electric current to the self-expandable mesh body when in an expanded configuration;
- and
- a nonconductive handle having a lumen extending therethrough that is in connection with the self-expanding mesh body.
