Implantable thermal treatment method and apparatus
First Claim
1. A method for providing long-term thermal therapy to a patient, comprising:
- positioning a delivery assembly at a location associated with a region of tissue of a spinal joint;
wherein the delivery assembly comprises a needle;
wherein the needle is delivered into and through at least a portion of a bony structure to the location;
wherein positioning a delivery assembly comprises positioning the delivery assembly into and through at least a portion of a vertebral body to the location, said vertebral body comprising a bony structure located above a lower vertebral endplate and below an upper vertebral endplate;
delivering a long-term thermal therapy implant through the needle to a treatment location within the bony structure of the vertebral body;
implanting the long-term thermal therapy implant at the treatment location;
delivering a therapeutic level of energy from the implant to the tissue; and
heating the region of tissue associated with the spinal joint so as to cause a therapeutic result in the tissue.

Abstract
A long-term implantable 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 effected 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 achieves other responses without appreciable remodeling.
