Abstract
A medical device includes an energy-generating unit configured to produce energy for conduction through tissue to treat tissue. Waste heat produced by the energy-generating unit during energy production is conducted to tissue to facilitate treating tissue.
Claims21
1-17. (canceled)
A medical device, comprising:
- first and second electrically and thermally conductive tissue treating surfaces;
- an electrical conductor disposed in electrical communication with the first tissue treating surface and configured to conduct RF energy to the first tissue treating surface for conducting RF energy through tissue disposed between the first and second tissue treating surfaces for heating tissue via Joule heating to treat tissue;
- and
- an electrically insulative thermal conductor disposed in thermal communication with the first tissue treating surface and configured to conduct heat to the first tissue treating surface for heating tissue adjacent the first tissue treating surface via conductive heating to facilitate treating tissue.

A medical device, comprising:
- first and second electrically and thermally conductive tissue treating surfaces;
- and
- an electrical conductor electrically coupled to the first tissue treating surface, the electrical conductor configured to conduct RF energy to the first tissue treating surface for conducting RF energy through tissue disposed between the first and second tissue treating surfaces for heating tissue via Joule heating to treat tissue;
- heat-generating electronics;
- and
- an electrically insulative thermal conductor thermally coupling the heat-generating electronics and the first tissue treating surface, the electrically insulative thermal conductor configured to conduct heat produced by the heat-generating electronics to the first tissue treating surface for heating tissue adjacent the first tissue treating surface via conductive heating to facilitate treating tissue.
3 more elements
A method of treating tissue, comprising:
- conducting RF energy, via an electrical conductor, to a first electrically and thermally conductive tissue treating surface such that the RF energy is conducted through tissue disposed between the first tissue treating surface and a second electrically and thermally conductive tissue treating surface to heat tissue via Joule heating to treat tissue;
- and
- conducting heat, via an electrically insulative thermal conductor, to the first tissue treating surface such that the first tissue treating surface is heated to heat tissue adjacent the first tissue treating surface via conductive heating to facilitate treating tissue.
