1. A system comprising:
- a) a primary catheter, wherein said primary catheter comprises a hollow primary lumen;
b) a channel catheter, wherein said channel catheter is concentrically positioned within said hollow primary lumen, and wherein said channel catheter comprises a channel lumen;
c) a steerable navigation catheter, wherein said steerable navigation catheter is configured to fit within said channel lumen, and wherein said steerable navigation catheter comprises a steerable tip and position sensing element; and
d) a microwave energy delivery device,wherein said energy delivery device is configured to fit within said channel lumen,wherein the microwave energy delivery device is of sufficient length to extend from the mouth of a human subject, through the trachea of the human subject, into the lung of the human subject and to the peripheral lung of the human subject,wherein the diameter of the microwave energy delivery device is approximately 2 mm or less;
wherein the microwave energy delivery device is flexible;
wherein the microwave energy delivery device comprises an inner conductor, an outer conductor, and a stylet tip,the inner conductor is a conductor of microwave energy,the outer conductor is a conductor of microwave energy,the inner conductor having a proximal end and a distal end,the outer conductor having a proximal end and a distal end,the stylet tip having a proximal end and a distal end,the stylet tip attached at the distal end of the microwave energy delivery device;
wherein the microwave energy delivery device has therein one or more coolant channels for circulating and recirculating coolant, wherein the one or more coolant channels does not extend to the distal end of the stylet tip;
wherein the microwave energy delivery device has thereon a temperature sensor.

Abstract
The present invention relates to comprehensive systems, devices and methods for delivering energy to tissue for a wide variety of applications, including medical procedures (e.g., tissue ablation, resection, cautery, vascular thrombosis, treatment of cardiac arrhythmias and dysrhythmias, electrosurgery, tissue harvest, etc.). In certain embodiments, systems, devices, and methods are provided for delivering energy to difficult to access tissue regions (e.g. peripheral lung tissues), and/or reducing the amount of undesired heat given off during energy delivery.
