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 treating a tissue region (e.g., a tumor) through application of energy.

Claims

1. A system comprising:

a) a first component comprising a microwave energy source and a coolant source comprising a coolant;

b) a second component for delivering microwave energy and the coolant from the first component, wherein said second component is separate from said first component;

c) one or more procedure device hub-energy delivery device cables;

d) a procedure device hub configured to receive the microwave energy and the coolant from the second component,

said procedure device hub comprising

a plurality of connection ports for attachment of the one or more procedure device hub-energy delivery device cables, wherein the one or more procedure device hub-energy delivery device cables connect said procedure device hub with an energy delivery device, wherein the energy delivery device has an exterior and an interior, wherein the one or more procedure device hub-energy delivery device cables are configured to deliver the microwave energy and the coolant from the procedure device hub to the interior of the energy delivery device,

wherein said procedure device hub is configured to perform adjustments of said delivery of said microwave energy and said coolant, wherein said adjustments comprise turning on said energy delivery device, turning off said energy delivery device, calibrating a timing of the delivery of said microwave energy and said coolant to said energy delivery device for purposes of avoiding undesired tissue heating during use of said energy delivery device, and calibrating a delivery amount of said microwave energy and said coolant to said energy delivery device for purposes of avoiding undesired tissue heating during use of said energy delivery device,

wherein said procedure device hub is separate from said energy delivery device,

wherein said procedure device hub is separate from said second component, wherein the second component comprises one or more cables connecting the first component with the procedure device hub,

wherein said procedure device hub is separate from said first component,

e) a processor comprising an algorithm, wherein the processor is configured to communicate with the procedure device hub, wherein the algorithm is configured to direct said procedure device hub to perform said adjustments of said delivery of said microwave energy and said coolant.

2. The system of claim 1, wherein said procedure device hub is mounted to a table, a cart, or a bed.

3. The system of claim 1, wherein said microwave energy source is locatable outside of a sterile field and said procedure device hub is locatable within or outside of said sterile field.

4. The system of claim 1, wherein said second component comprises a transport sheath encompassing said one or more cables connecting the first component with the procedure device hub.

5. The system of claim 1, wherein said procedure device hub has therein a power splitter for adjusting an amount of the microwave energy delivered to said energy delivery device.

6. The system of claim 1, wherein each of said one or more procedure device hub-energy delivery device cables is less than four feet in length.

7. The system of claim 1, wherein said coolant is carbon dioxide gas.

8. The system of claim 7, wherein said carbon dioxide gas is at its vapor-liquid critical point.

9. The system of claim 1, wherein said procedure device hub or said first component has a sensor configured to automatically inhibit the delivery of microwave energy upon an occurrence of one or more of the undesired tissue heating, undesired leak, or undesired change in pressure.
