David O. Kubiatowicz 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).

  • Shielding device for radioactive seed
    Patent number: 4509506
    Abstract: Radioactive seeds contained in a suture material are shielded during shipping and storage inside a curved tube of dense material having two open ends. The suture material protrudes through at least one end of the tube. Preferably, one end of the suture material has removable means for preventing the end from entering the tube prematurely, and the other end is attached to a needle.The seeds spaced from the open ends of the curved tube so as to prevent radiation from escaping from the tube.
    Type: Grant

    Date of Patent: April 9, 1985
    Assignee: Minnesota Mining & Manufacturing Co.
    Inventors: David C. Windorski, David O. Kubiatowicz
  • Radioactive iodine seed
    Patent number: 4323055
    Abstract: Improved radioactive iodine seeds are disclosed wherein the carrier for the radioisotope is a rod-like member which is detectable by X-rays and occupies a substantial portion of the space within the seed.

  • 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.
