INDUCING DESIRABLE TEMPERATURE EFFECTS ON BODY TISSUE

摘要

The present invention relates to a system for remodeling tissue disposed about a blood vessel, the system comprising an endovascular catheter having an energy delivery portion, the energy delivery portion having a plurality of bipolar electrode pairs mounted on an outer surface of a balloon of the catheter and arranged in an array, wherein adjacent bipolar electrode pairs are spaced around the axis of the balloon so that the energy delivery results in gaps between adjacent electrode pairs about the axis of the balloon; and an energy source coupleable with the catheter, the energy source configured to deliver controlled quantities of energy to each of the bipolar electrode pairs in response to an input.
