  • Patent number: 9421280
    Abstract: A method of determining the patency of a donor organ or at least one vessel to a donor organ in a donor subject includes administering a fluorescent dye to the donor subject, applying a sufficient amount of energy to the vessel such that the fluorescent dye fluoresces, obtaining a fluorescent image of the donor organ or the vessel attached to a donor organ, and observing the image to determine if a fluorescent signal is continuous through the vessel. A continuous fluorescent signal in the donor organ or vessel indicates the respective donor organ or vessel is patent.

  • Publication number: 20150112193
    Abstract: Methods for assessing perfusion in a portion of tissue in an animal may include administering a fluorescent dye to the animal such that the fluorescent dye enters the portion of tissue, exciting the fluorescent dye within the portion of tissue with a source of illumination such that the fluorescent dye emits radiation, capturing the radiation emitted by the fluorescent dye with a camera, and obtaining at least one image of the fluorescence radiation emitted from the portion of tissue

  • Publication number: 20150112192
    Abstract: Methods for assessing blood flow in vasculature in a portion of tissue in an animal may include administering a fluorescent dye to the animal such that the fluorescent dye enters the portion of tissue, exciting the fluorescent dye within the portion of tissue with a source of illumination such that the fluorescent dye emits radiation, capturing the radiation emitted by the fluorescent dye with a camera capable of capturing a series of angiographic images within the portion of tissue, and evaluating the series of angiographic images to assess blood flow in the vasculature in the tissue portion.

  • Patent number: 8892190
    Abstract: Method for assessing the patency of a patient's blood vessel, advantageously during or after treatment of that vessel by an invasive procedure, comprising administering a fluorescent dye to the patient; obtaining at least one angiographic image of the vessel portion; and evaluating the at least one angiographic image to assess the patency of the vessel portion. Other related methods are contemplated, including methods for assessing perfusion in selected body tissue, methods for evaluating the potential of vessels for use in creation of AV fistulas, methods for determining the diameter of a vessel, and methods for locating a vessel located below the surface of a tissue.
