Devices and methods for percutaneous energy delivery

摘要

The invention provides a system and method for percutaneous energy delivery in an effective, manner using one or more probes. Additional variations of the system include array of probes configured to minimize the energy required to produce the desired effect.

主权项

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, where 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 axially spaced from the device body adjacent to the tissue engaging surface and being spaced from the plurality of energy transfer elements where axial spacing of the stabilization plate allows direct visual observation of the stabilization plate by a user when placed against the surface of tissue; 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 and where the stabilization plate is located directly above the target region on the surface of tissue.
