Abstract: A minimally invasive applicator device for treatment of intervertebral tissue containing at least one target nerve includes an insertion device having a proximal end and a distal end for insertion into the intervertebral tissue containing at least one target nerve, an ultrasound transducer device coupled to the distal end of the insertion device, and an external RF power generator electrically that provides power to the ultrasound transducer device. The ultrasound transducer device includes an array of a plurality of transducer crystals which are all aligned along a line defined by an axis enclosed by each of the plurality of transducer crystals disposed sequentially and longitudinally adjacent each other along the axis to form a customized flexible array along the applicator device. Ultrasound radiative output treatment outward from the axis of the transducer crystals allows for treatment of the intervertebral tissue containing at least one target nerve.

Abstract: An ultrasound device and method for the treatment of intervertebral disc tissue for remediation of back pain. An applicator comprises a catheter and/or needle with a distal tip including one or more ultrasound transducer crystals. The crystals produce high-powered ultrasound energy that is transmitted and absorbed in the disc tissue. The resulting temperature elevation of the disc tissue shrinks the collagen fibers in the surrounding tissue, and/or destroying small nerves that may have invaded and innervated the surrounding degenerated tissue, and can provide increased structural integrity and disc support for the fragmented nucleus pulposus to relieve pressure on the spinal nerves.

Abstract: An apparatus and method for shielding non-target tissues and organs during thermotherapy, brachytherapy or other treatment of a diseased target tissue. The apparatus includes a catheter shaft having input and output lumens and at least one inflatable balloon. A plurality of input lumens within the catheter shaft allows the passage of liquid or gas through an input port and into the interior of the balloon thereby inflating the balloon. The gas or liquid can then be cycled through the inflated balloon through an output port and output lumen and out of the catheter shaft. Temperature sensors or other sensors may be attached to the balloon or catheter to monitor temperature or other conditions at the treatment site. The catheter is positioned between the target tissue or organ and sensitive non-target tissues in proximity to the target tissue and inflated causing a physical separation of tissues as well as a physical shield.
