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. |

Method and device for quantification of neuromuscular stimulations due to RF-currents
A two-part NMS-test bench is provided with which instruments, generator voltages, and surgery modes can be evaluated with regard to neuromuscular stimulations. By separating the NMS-test bench in a first part for application of the instrument and in the second part for evaluation of the physiological effect on nerves, a measurement free of artifacts is possible. The spatial and timely separation of the RF-application from the recording of the compound action potentials makes RF-disturbances ineffective. The electrical signals gained in the instrument test chamber can be pre-processed. The recorded electrical signals emitted from the instrument can be evaluated at the nerve model an arbitrary number of times. The variance involved with the recording of compound action potentials during direct use of the instrument can thus be minimized. The separated test of the signals at the nerve model avoids thermal damage of a prepared nerve and falsification of measurement results. |
