  • Patent number: 9649127
    Abstract: A system for thermal treatment or ablation of tissue includes an ultrasonic thermal ablation probe, an ultrasonic three-dimensional imaging probe that captures an image from radio frequency image data obtained before the radio frequency image data is processed, a control system for multi-axis control of the imaging probe's position, and an ultrasonic feedback mechanism that measures ultrasound echo strain to estimate heat-induced structural changes of an area surrounding the ultrasonic thermal ablation probe, from the image. The ultrasonic thermal ablation probe is either an interstitial ablator inserted into tissue, a natural cavity or a vessel to emit high intensity ultrasound energy to deposit thermal dose, or an external applicator that emits a directional high intensity ultrasound energy to deposit thermal dose via surface contact with tissue. The control system adjusts power levels of the ultrasonic thermal ablation probe based on the estimated heat-induced structural changes.

  • Publication number: 20150367147
    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.

  • Publication number: 20150216621
    Abstract: Disclosed is a system and method for registering images from two medical imaging modalities in a six-degree-of-freedom coordinate space, for the purpose of providing real time registered imagery for optimization of medical procedures. The system and method uses fiducial that is visible to the first imager and in a fixed position and orientation relative to the second imager. The first imager may be an X-ray device such as a C-arm fluoroscope, and the second imager may be a Transrectal Ultrasound (TRUS) device.

  • Patent number: 9060670
    Abstract: Three dimensional heat-induced echo-strain imaging is a potentially useful tool for monitoring the formation of thermal lesions during ablative therapy. Heat-induced echo-strain, known as thermal strain, is due to the changes in the speed of propagating ultrasound signals and to tissue expansion during heat deposition. This paper presents a complete system for targeting and intraoperative monitoring of thermal ablation by high intensity focused acoustic applicators. A special software interface has been developed to enable motor motion control of 3D mechanical probes and rapid acquisition of 3D-RF data (ultrasound raw data after the beam-forming unit). Ex-vivo phantom and tissue studies were performed in a controlled laboratory environment. While B-mode ultrasound does not clearly identify the development of either necrotic lesions or the deposited thermal dose, the proposed 3D echo-strain imaging can visualize these changes, demonstrating agreement with temperature sensor readings and gross-pathology.

  • Publication number: 20150018727
    Abstract: A high-power ultrasound heating applicator for minimally-invasive thermal treatment of uterine fibroids or myomas. High-Intensity interstitial ultrasound, applied with minimally-invasive laparoscopic or hysteroscopic procedures, is used to effectively treat fibroids within the myometrium in lieu of major surgery. The applicators are configured with high-power capabilities and thermal penetration to treat large volumes of fibroid tissue (>70 cm3) in short treatment times (3-20 minutes), while maintaining three-dimensional control of energy delivery to thermally destroy the target volume.
