  • Method for detection of fibrin clots
    Patent number: 6977068
    Abstract: A method for the detection of fibrin in a source, in particular the in vivo detection of a fibrin in a patient, the method comprising supplying to the source or patient an amount of a detectable reagent comprising a plurality of discrete particles, each of the particles comprising a plurality of layers of carbon and being capable of binding to fibrin; and detecting the presence of the particles in the source. The particles may also comprise a detectable marker encased in said plurality of layers of carbon, the presence of said marker being capable of detection in said source.

  • Device for producing a gas-lite radionuclide composition
    Patent number: 5228444
    Abstract: A diagnostic device, composition and method of diagnosing airway dysfunction in a patient, the apparatus and method require the subjecting of a pharmaceutical acceptable radionuclide, that is the composition, to an elevated temperature in an enclosed spaced to produce an inhalable gas-light product containing the vapour of the radionuclide in the space, delivery of the inhalable gas from the space is governed with the inhalable gas being inhaled by a patient to enable a film to be located adjacent the airways enabling mapping of the deposition of the radionuclide in the airways of the patient's lungs.

    Inventor: William M. Burch
  • Method of forming a radioactive metallic vapor
    Patent number: 5064634
    Abstract: A diagnostric device, composition and method of diagnosing airway dysfunction in a patient is disclosed. The apparatus and method require the subjecting of a pharmaceutical acceptable radionuclide, that is the composition, to an elevated temperature in an enclosed space in the presence of either an inert gas or oxygen to produce an inhalable product. The product is inhaled by a patient. A film is located adjacent the airways enabling mapping of the deposition of the radionuclide in the airways of the patient's lungs.

  • Diagnostic compositions
    Patent number: 4280991
    Abstract: The invention discloses diagnostic compositions for use in obtaining images of a patient's lungs. The basic components of the composition of the invention are sodium pertechnetate which is radioactive and ethanol. This composition may be combusted and the resulting products cooled or alternatively the composition may be inserted into a pressure vessel with an aerosol. In both cases a gas like mixture results. A particular advantage is that a patient is able to breath the mixture of the invention in a normal way and does not need to undergo any training in inhalation.
