Abstract
An electrosurgical balloon includes an inflatable balloon body formed of a non-conductive substrate material. One or more electrodes are disposed on an exterior surface of the balloon body. The electrodes can include a pair of bipolar electrodes, and the balloon body can have at least one fluid outlet hole configured to provide fluid to the pair of bipolar electrodes. A second inflatable balloon body can be disposed inside the first inflatable balloon body. The electrosurgical balloon can be incorporated into a catheter assembly, in which the electrosurgical balloon is a balloon electrode tip at a distal end of a catheter.
Claims3
An electrosurgical balloon, comprising:
- an inflatable balloon body having a proximal end and a distal end and defining a circumference, wherein the balloon body is formed of a nonconductive substrate material;
- a pair of bipolar electrodes disposed on an opposite sides of an exterior surface of the inflatable balloon body, the pair of electrodes including a first electrode and a second electrode in a bipolar electrode configuration, each the first electrode and the second electrode extending partially around the circumference of the inflatable balloon body;
- and
- at least one fluid outlet hole in the balloon body configured to provide a conductive fluid from a fluid source to the pair of bipolar electrodes.
