  • Patent number: 10315055
    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.

    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 side wall of the moxibustion canister is provided with several air inlets (7) and air outlets (11), so the combustion speed of the moxa column (5) can be adjusted through the size of the air outlets, thereby adjusting the temperature and time of the moxibustion.

  • Patent number: 9393080
    Abstract: To improve the overall navigation process for minimally invasive repair of heart valve leaflets, an augmented reality technique capable of providing a robust three-dimensional context for transesophogeal echocardiography data has been developed. In the context of various embodiment of the invention, augmented reality essentially refers to a system in which the primary environment is virtual but the environment is augmented by real elements. In this real-time environment, the surgeon can easily and intuitively identify the tool, surgical targets, and high risk areas, and view tool trajectories and orientations.

  • Patent number: 9259287
    Abstract: Patient specific temperature distribution in organs, due to an ablative device, is simulated. The effects of ablation are modeled. The modeling is patient specific. The vessel structure for a given patient, segmented from medical images, is accounted for as a heat sink in the model of biological heat transfer. A temperature map is generated to show the effects of ablation in a pre-operative analysis. Temperature maps resulting from different ablation currents and ablation device positions may be used to determine a more optimal location of the ablative device for a given patient. Other models may be included, such as accounting for the tissue damage during the ablation.
