  • Publication number: 20160042084
    Abstract: Methods of monitoring, maintaining, and/or restoring viability of at least one organ in a perfusion apparatus are disclosed. The methods include monitoring data comprising information relating to events occurring while at least one organ is present in a perfusion apparatus to form a data record. And they further include connecting the perfusion apparatus to a network through wiring or wirelessly, and continuously uploading the data record to a database at a location away from the perfusion apparatus in such a manner that a database computer that obtains the data record from the database can at least one of manage, track, monitor, and diagnose the at least one organ in the perfusion apparatus in real-time based upon the information in the data record.

  • Patent number: 8962303
    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. In perfusion, organ perfusion pressure is preferably controlled in response to a sensor disposed in an end of tubing placed in the organ, by a pneumatically pressurized medical fluid reservoir, providing perfusion pressure fine tuning, overpressurization prevention and emergency flow cut-off. In the hypothermic mode, the organ is perfused with a medical fluid, preferably a simple crystalloid solution containing antioxidants, intermittently or in slow continuous flow. The medical fluid may be fed into the organ from an intermediary tank having a low pressure head to avoid organ overpressurization. Viability of the organ may be automatically monitored, preferably by monitoring characteristics of the medical fluid perfusate.

  • Patent number: 8609400
    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. Viability of the organ may be automatically monitored, preferably by monitoring characteristics of the medical fluid perfusate. The perfusion process can be automatically controlled using a control program.

  • Patent number: 8431385
    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: 8431523
    Abstract: Oligomeric acylated biosurfactants (“OABs”) having low critical micelle concentrations of from about 1.0 ppm to about 200 ppm, preferably less than about 50 ppm, in an aqueous solution of Minimal Essential Media that can lower the surface tension in the aqueous MEM environment to less than about 50 dynes/cm2 and have the ability to increase metabolic soluble proteins and/or increase synthesis of extracellular skin matrix proteins and/or increase rates of cell turnover while at the same time exhibiting comparatively low toxicity—preferably, an LD50 of greater 200 ppm in 37 year-old female fibroblast cells. Another aspect of the present invention is directed to the use of OABs in formulations that are topically-applied, by which is meant the formulation is placed in direct contact with the skin, hair and nails as well as mucosa of the eyes, ears, nose, mouth, anus and vagina.
