Devices and methods for treatment of luminal tissue
First Claim
1. An electrode deployment apparatus for treatment of tissue in a body lumen, the apparatus comprising:
- a plurality of electrodes arranged on a surface of a dimensionally stable support at a pre-selected electrode density; and
an expansion member coupled to the support to deploy and selectively expose a portion of the electrode surface while shielding a remaining portion and maintaining the electrode density.

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.

34. A method for deploying electrodes to treat tissue in a body lumen, said method comprising:
-
positioning an array of electrodes having a pre-selected electrode density within the body lumen; and
exposing an area of the array sufficient to engage a wall of the lumen while maintaining the electrode density, wherein the size of the exposed area will vary depending on the size of the body lumen. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46)
