1. An electrode deployment apparatus for treatment of tissue in a body lumen, the apparatus comprising:
- an expansion member having a surface; and
a dimensionally-stable support having a first end, a second end and a surface;
a plurality of electrodes arranged on the surface of the support;
the support and the expansion member coupled together at attachment sites near the first end and the second end of the support, the support furled around the expansion member in a non-overlapping configuration to provide a circumferential portion of the expansion member covered by the support.

Abstract
Devices and methods are provided for treatment of tissue in a body lumen with an electrode deployment device. Embodiments typically include a device with a plurality of electrodes having a pre-selected electrode density arranged on the surface of a support. The support may comprise a non-distensible electrode backing that is spirally furled about an axis and coupled to an expansion member such as an inflatable elastic balloon. In some embodiments, the balloon is inflated to selectively expose a portion of the electrode surface while maintaining the electrode density.
