    Abstract: HIFU treatment of localized prostate cancer includes identifying the cancer locations in a patient's prostate and visually segmenting the patient's prostate into areas for analysis and treatment. The section including the most aggressive cancer is determined to be the primary area and subjected to a first full HIFU treatment for a period intended to ablate the cancer. HIFU treatment is then stopped on the primary area, allowing it to rest, while simultaneously subjecting the next contiguous area of the prostate to HIFU treatment to ablate any additional areas of suspected cancer. HIFU treatment is then stopped in the contiguous area. The primary area is then subjected to a second full HIFU treatment for a period sufficient to ensure the complete ablation of the cancerous tumor. Repeating alternating full HIFU treatment on subsequent contiguous areas of the prostate ensures the complete ablation of any cancerous tumors in the prostate.

  • Patent number: 9757582
    Abstract: In the treatment of a tumor (126) with radiation therapy (122) is enhanced by a weak magnetic field (130), the field strength time sequence of exposure and shape and contour of the magnetic field are varied to achieve desired results. In one separate aspect, exposure to a magnetic field (130) is continued after exposure to a free radical-creating therapy is ceased or diminished, thereby increasing the lifetimes of free radicals that have already been created. In another preferred embodiment a magnetic field (13) is strategically placed to avoid extending the lives of free radicals in tissue through which a free radical-creating beam must pass, to reach a tumor. This application discloses quantitative parameters for field strength and exposure time to create concentrations and reactivity of free radicals, including long-lived free radicals and discloses the use of shaped, contoured, and designed electromagnetic fields. A treatment planning station (200) is also disclosed.

  • Patent number: 9724158
    Abstract: A microwave ablation system includes a power source. A microwave antenna is adapted to connect to the power source via a coaxial cable that includes inner and outer conductors having a compressible dielectric operably disposed therebetween. The inner conductor in operative communication with a radiating section associated with the microwave antenna. The outer conductor includes a distal end transitionable with respect to each of the inner conductor, compressible dielectric and radiating section from an initial condition wherein the distal end has a first diameter to a subsequent condition wherein the distal end has second diameter. Transition of the distal end from the initial condition to the subsequent condition enhances the delivery of microwave energy from the power source to the inner conductor and radiating section such that a desired effect to tissue is achieved.
