Patent ID: 7883481

Claim:
An ultrasound treatment device comprising: an optical navigating device having at least one diagnostic camera that is adapted to produce at least one picture or image of an anatomic structure of a treatment area; at least one therapeutic ultrasound transducer adapted for insertion through the skin of a patient having a vertebral column and placement against an intervertebral disc to be treated; and having a longitudinally extending side wall and a distal end wall; at least one cooling chamber in which cooling liquid is provided; at least one ultrasound transmitting element provided at one end of the cooling chamber, where the orientation of at least one ultrasound transmitting element is substantially distally-directed, whereby the at least one ultrasound transmitting element is configured to substantially transmit through the distal end wall, and where the cooling chamber with cooling liquid is located between the at least one ultrasound transmitting element and the distal end wall and being configured to cool the ultrasound transmitting element and the tissue closest to the ultrasound transducer; and at least one temperature sensor provided to measure the temperature at the treatment area, wherein the optical navigating device further comprises at least one signal receivinq or signal sending unit, at least one position transmitter, and a reference device wherein the at least one signal receiving or signal sending unit is adapted to send signals to and receive reflected or other signals from the at least one position transmitter on: a) the reference device wherein the reference device has a set position relative to the disc, and b) the therapeutic ultrasound transducer such that the position thereof relative to said treatment area can be determined.
