DEVICES FOR REMODELING TISSUE OF OR ADJACENT TO BODY PASSAGE

摘要

PROBLEM TO BE SOLVED: To provide devices for remodeling tissue of or adjacent to a body passage.SOLUTION: A device 120 comprises: a catheter 130 extending to an expandable member disposed along a longitudinal axis L from the proximal end to the distal end thereof, the expandable member defining a plurality of circumferential zones A, B, C, D along the longitudinal axis in an expanded state; and a plurality of assemblies, each assembly comprising a bipolar electrode pair coupled to the expandable member, and each assembly comprising a distal electrode longitudinally separated from a proximal electrode by an intermediate tail. Each circumferential zone comprises at least one electrode of at least one of the plurality of circumferential zones. Energy applied by the plurality of assemblies forms at least one treatment region in each circumferential zone.SELECTED DRAWING: Figure 1B
