  • Devices and methods for treatment of cancers
    Patent number: 10322298
    Abstract: Devices and methods for brachytherapy treatment are disclosed. One aspect is a poly(methyl methacrylate) apparatus for brachytherapy treatment at the vaginal apex. Another aspect is a poly(methyl methacrylate) apparatus for brachytherapy treatment in the distal two-thirds of the vagina. Another aspect is a poly(methyl methacrylate) apparatus for brachytherapy treatment of cancers that are offset from the vaginal apex. Other aspects include methods for guiding needles for treatment of cancers at the vaginal apex, in the distal two-thirds of the vagina, and that are offset from the vaginal apex.

  • Enhanced micro-radiation therapy and a method of micro-irradiating biological systems
    Patent number: 7283610
    Abstract: A micro-radiation therapy apparatus includes an isotope-based micro-radiotherapy brachytherapy small animal irradiator useful for radiating a biological system, the irradiator having an external radiation source proximate the biological system comprising a collimated radiation beam. A method of effectively irradiating at least one cell in a biological system includes applying micro-radiation from an isotope-based micro-radiation small animal irradiator, the irradiator having an external radiation source proximate the biological system including a collimated radiation beam to a target cell of the biological system.
