Title: Method for ultrasonic treatment of disc disease

Abstract: The present invention relates to a device for non-invasive treatment of biological tissue, whereby the treatment aim at changing or degenerating said tissue. This device has a treatment transducer (2) comprising at least one ultrasonic transducer (3 and/or 4) which is provided to treat intervertebral discs (1), preferably nucleus pulposus (1a), by means of ultrasound, whereby the ultrasonic field of the ultrasonic transducer (3 and/or 4) is focused in said intervertebral disc (1), preferably in nucleus pulposus (1a), for heating the tissue therein, to such temperatures that the tissue in the focal area (5) degenerates, whereby the pressure in the intervertebral disc (1) and thus, the pressure against the spinal cord (6) is reduced.
