Blood Patents (Class 424/529)
  • Patent number: 7498156
    Abstract: This invention is directed towards a method of using visible light at wavelengths of at least 500 nm and above in combination with a sensitizer having a flavin moiety to reduce any pathogens that may be contained in blood and blood components. By exposing the blood and blood components to light of 500 nm and higher, only the sensitizer that is bound to nucleic acids of the pathogens will be activated, thus destroying the sensitizer-pathogenic nucleic acid complex. Because unbound sensitizer is not activated at this wavelength, damage to blood and blood components caused by photolysis of unbound sensitizer may be avoided.

    Abstract: A process for manufacturing a fibrin membrane from blood plasma that was partially depleted and subjected to coagulation by adding a solution of a physiological coagulating agent, leaving the mixture to stay until forming a gelatinous blood clot, and then dehydrating said blood clot to obtain a fibrous membrane, which is subjected to washing with softening agents and then to drying until obtaining a flexible and mouldable membrane. The membrane so obtained is capable to provide an immediate and complete haemostasis, followed by a whole reabsorption, without risk of adhesions with the neighboring tissues, up to the cicatrisation of the injured tissue. The membrane is mouldable and elastic, and is provided with high mechanical properties. It may be soaked with disinfectant agents, drugs or tissue growth factors.

  • Patent number: 6942879
    Abstract: A novel cell seeded hollow fiber bioreactor is described as a potential bioartificial kidney. Endothelial cells along with pericyte, vascular smooth muscle, and/or mesangial cells or any mesenchymally derived support cells are seeded along a hollow fiber in a perfused bioreactor to reproduce the ultrafiltration function and transport function of the kidney. Maintenance of tissue specific function and ultrastructure suggest that this bioreactor provides an economical device for treating renal failure.

  • Patent number: 6855489
    Abstract: Systems and methods treat plasma carrying contaminants and cellular matter that are capable of entraining contaminants. The systems and methods separate cellular matter from the plasma by filtration, thereby removing contaminants entrained within the cellular matter. The system and methods add to the plasma a photoactive material. The systems and methods emit radiation at a selected wavelength into the plasma to activate the photoactive material and thereby eradicate the contaminant that is free of entrainment by cellular matter.

  • Publication number: 20040253317
    Abstract: Pharmaceutical preparation for the treatment and follow-up care of tumors that comprises the blood plasma or predetermined blood plasma components of equidae animals with pair number of fingers, preferably cattle being not endangered lethally by leucosis. The predetermined fraction is the material bovin 40 and/or bovin 300 constituting the difference detectable by electrophoresis between the lipid-free fraction taken from a cattle having leucosis and the lipid-free fraction taken from a healthy cattle.
