  • Patent number: 10391330
    Abstract: Products, compositions, systems, and methods for modifying a target structure which mediates or is associated with a biological activity, including treatment of conditions, disorders, or diseases mediated by or associated with a target structure, such as a virus, cell, subcellular structure or extracellular structure. The methods may be performed in situ in a non-invasive manner by application of an initiation energy to a subject thus producing an effect on or change to the target structure directly or via a modulation agent. The methods may further be performed by application of an initiation energy to a subject in situ to activate a pharmaceutical agent directly or via an energy modulation agent, optionally in the presence of one or more plasmonics active agents, thus producing an effect on or change to the target structure. Kits containing products or compositions formulated or configured and systems for use in practicing these methods.

  • Publication number: 20190184190
    Abstract: A phosphor-containing drug activator activatable from a Monte Carlo derived x-ray exposure for treatment of a diseased site. The activator includes an admixture or suspension of one or more phosphors capable of emitting ultraviolet and visible light upon interaction with x-rays, wherein a distribution of the phosphors in the diseased target site is based on a Monte Carlo derived x-ray dose distribution. A system for treating a disease in a subject in need thereof, includes the drug activator and a photoactivatable drug, one or more devices which infuse the photoactivatable drug and the activator including the pharmaceutically acceptable carrier into a diseased site in the subject; and an x-ray source which is controlled to deliver the Monte Carlo derived x-ray exposure to the subject for production of ultraviolet and visible light inside the subject to activate the photoactivatable drug and induce a persistent therapeutic response, the dose comprising a pulsed sequence of x-rays delivering from 0.

  • Publication number: 20190168015
    Abstract: A system and method for light stimulation within a medium. The system has a reduced-voltage x-ray source configured to generate x-rays from a peak applied cathode voltage at or below 105 kVp, and a plurality of energy-emitting particles in the medium which, upon radiation from the x-ray source, radiate at a first lower energy than the x-ray source to interact witht least one photoactivatable agent in the medium. The method introduces the plurality of energy-emitting particles into the medium, radiates the energy-emitting particles in the medium with x-rays generated from a peak applied cathode voltage at or below 105 kVp; and emits a lower energy than the x-ray source to interact with the medium or with at least one photoactivatable agent in the medium.
