  • Enhanced cardiac radionuclide imaging techniques
    Patent number: 7526331
    Abstract: A cardiac imaging technique comprises (a) introducing a sufficient quantity of a not highly attenuating gas into the stomach of a patient to distend the stomach wall of the patient; and (b) while the stomach wall of the patient is distended, performing radionuclide imaging of the heart and/or of the heart's contents. Preferably, the gas used to distend the stomach wall is introduced into the patient (i) by having the patient ingest a substance that, when contacted with water or with stomach contents, produces the gas, (ii) by having the patient imbibe a liquid which has been mixed or combined with a gas-producing substance, or (iii) by having the patient imbibe a liquid into which the gas has been dissolved.

  • Rubbery products that shrink due to the application of energy and hypo-allergic rubbery products
    Patent number: 6946172
    Abstract: Rubbery products having a transition temperature that shrink from a second shape and size toward their original shape and size upon application of energy equivalent in result to raising the temperature of the rubbery product above the transition temperature. Also, hypo-allergenic rubbery products made from polybutadiene and its copolymers, trans-1,4-polybutadiene and its copolymers, synthetic isoprene and its copolymers, or synthetic cis-1,4-polyisoprene and its copolymers. Such rubbery products (not all of which need to be made to shrink) can be used in condoms, gloves, catheters, baby-bottle nipples, and dental dams, to name just a few.
