Theodore F. Bolles has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Technetium-labeled complexes, production and use thereof
    Patent number: 4208398
    Abstract: Novel chemical complexes containing a radioactive technetium isotope are kidney specific when the complexing agents are certain ionic, water-soluble mercaptans. The complexes can be made by reducing pertechnetate ion and reacting the reduced technetium species with the mercaptan. The complexes are normally used in a biologically sterile, substantially isotonic aqueous medium, for diagnostic purposes.
    Type: Grant
    Filed: April 21, 1975
    Date of Patent: June 17, 1980
    Assignee: Hoffman-La Roche Inc.
    Inventors: David O. Kubiatowicz, Theodore F. Bolles
  • Technetium-labeled complexes, production and use thereof
    Patent number: 4031198
    Abstract: A radiopharmaceutical kit for complexing a liver-specific agent labeled with technetium-99m comprising (1) a biologically sterile aqueous medium wherein the complex formation occurs, (2) a complexing agent which is a lipophilic mercaptan or thioketal and (3) a pharmaceutically acceptable reducing agent for technetium-99m.
    Type: Grant
    Filed: May 30, 1974
    Date of Patent: June 21, 1977
    Assignee: Minnesota Mining and Manufacturing Company
    Inventors: Richard A. Jackson, Theodore F. Bolles
  • Optically-transparent radiation-shielding composition
    Patent number: 3937970
    Abstract: An optically transparent, essentially colorless radiation shielding material for high energy radiation contains a combination of lead or thallium salts of C.sub.1 to C.sub.5 organic acids and may contain lead or thallium salts of mineral acids. Shields of complex shapes are easily constructed.
