Method of treating back pain with microwave sources
First Claim
1. A method for treating back pain of a subject, the method comprising:
- forming a bore into a bony structure of a vertebral body of a spine of the subject;
inserting a distal end of an energy delivery device within the vertebral body through the bore,wherein the energy delivery device comprises a cooling balloon;
wherein the energy delivery device comprises one or more energy sources;
activating the one or more energy sources to deliver energy to a target region within the vertebral body sufficient to denervate the target region; and
circulating cooling fluid through the energy delivery device to cool the balloon;
wherein the energy delivery device is positioned within the bony structure of the vertebral body when the one or more energy sources are activated; and
wherein the one or more energy sources comprise one or more microwave sources.

Abstract
An ultrasound therapy system and method is provided that provides directional, focused ultrasound to localized regions of tissue within body joints, such as spinal joints. An ultrasound emitter or transducer is delivered to a location within the body associated with the joint and heats the target region of tissue associated with the joint from the location. Such locations for ultrasound transducer placement may include for example in or around the intervertebral discs, or the bony structures such as vertebral bodies or posterior vertebral elements such as facet joints. Various modes of operation provide for selective, controlled heating at different temperature ranges to provide different intended results in the target tissue, which ranges are significantly affected by pre-stressed tissues such as in-vivo intervertebral discs. In particular, treatments above 70 degrees C., and in particular 75 degrees C., are used for structural remodeling, whereas lower temperatures achieve other responses without appreciable remodeling.
