First Claim
Patent Images
1. An energy delivery device for delivering energy from an energy supply unit to a target region beneath a surface of tissue, the device comprising:
- a device body having a tissue engaging surface, here the tissue engaging surface allows orientation of the device body on the surface of tissue;
a first plurality of energy transfer elements being advanceable from the device body at an oblique angle relative to the tissue engaging, surface;
a stabilization plate adjacent to the tissue engaging surface and being spaced from the plurality of energy transfer elements; and
a connector adapted to couple the energy supply unit to the plurality of energy transfer elements;
wherein the tissue engaging surface and stabilization plate are positioned such that when the tissue engaging surface is placed on the surface of tissue and the first plurality of energy transfer elements is advanced into the surface of tissue at an entry point, the first plurality of energy transfer elements enters the tissue at the oblique angle relative to the tissue surface while the tissue engaging surface and the stabilization plate reduce movement of the surface of tissue adjacent to the entry point.

117. A system configured to treat tissue, the system comprising:
-
all array of electrically isolated electrode pairs adapted to penetrate the tissue; and a controller for providing energy to at least one of the electrode pairs in the array of electrode pairs, where the controller independently controls application of energy between electrode pairs in the array to confine flow of energy to between each electrode in the pair to create a plurality of fractional lesions within the tissue between adjacent electrode pairs. - View Dependent Claims (118, 119, 120, 121, 122)
