Abstract

A method and system are provided treating a tissue site of a ti ssue structure that has at least a first and second tissue plan e. An energy delivery device is provided. A barrier is created between the first and second tissue planes. At least a portion of an energy delivery device(10) is positioned at the tissue site. Sufficient energy is delivered from the energy delivery device to create cell necrosis of at least a portion of the first tissue plane.
