1. An expandable device for thermally affecting tissue, the device comprising:
- a fluid conduit, the fluid conduit including;
a fluid inlet conduit;
a fluid outlet conduit; and
a substantially planar spiral-shaped section having a first end and a second end;
a first lumen and a second lumen extending the length of the spiral-shaped section;
wherein the first lumen is connected to the second lumen at the second end of the spiral-shaped section, and wherein the fluid inlet conduit and the fluid outlet conduit are arranged to couple with the first end of the spiral-shaped section, wherein the spiral-shaped section defines a tissue contact region, the tissue contact region being operable to contact and thermally affect a tissue to be treated.

Abstract
A method and expandable device for thermally affecting tissue in which there is a fluid conduit. The fluid conduit defining a spiral-shaped element. The fluid conduit includes a wall defining an inner volume. The inner volume being configured to pass thermally transmissive fluid. Optionally, the tissue contact region is operable to have a first contact surface area and a second contact surface area in which the second contact surface area is larger than the first contact surface area. A method of use of the device is provided.
