  • Publication number: 20040058432
    Abstract: An organ perfusion apparatus and method monitor, sustain and/or restore viability of organs and preserve organs for storage and/or transport. Other apparatus include an organ transporter, an organ cassette and an organ diagnostic device. The method includes perfusing the organ at hypothermic and/or normothermic temperatures, preferably after hypothermic organ flushing for organ transport and/or storage. The method can be practiced with prior or subsequent static or perfusion hypothermic exposure of the organ. Organ viability is restored by restoring high energy nucleotide (e.g., ATP) levels by perfusing the organ with a medical fluid, such as an oxygenated cross-linked hemoglobin-based bicarbonate medical fluid, at normothermic temperatures.

  • Patent number: 5897007
    Abstract: A nursing bottle helps reduce tooth decay. The nursing bottle contains a first reservoir for water, a second reservoir for a cariogenic liquid, and a nipple with two fluid flow paths. The first fluid flow path runs from the cariogenic liquid reservoir to an outlet opening in the tip of the nipple. The second fluid flow path runs from the water reservoir to lateral outlet openings near the tip of the nipple. When the reservoirs are filled and the bottle is used, the water enters the baby's mouth nearer the teeth than does the cariogenic liquid, thereby rinsing the teeth and reducing tooth decay.
