  • Patent number: 9888680
    Abstract: The vasculature of a donor lung is perfused with a lung preserving fluid to preserve its structure. At the same time, a decellularization fluid is perfused through the airways, which strips away donor cells. The decellularized region is then seeded with pulmonary cells of the transplant recipient, which regenerate the lung. The pulmonary cells may be derived from stem cells, and the decellularization can be targeted to reduce the quantity of cells required.

  • Publication number: 20170246339
    Abstract: The present invention provides hemostatic compositions comprising components of the flowers of pharmaceutical chamomile (Chamomilla recutita), the leaves of dioecious nettle (Urtica dioica), kaolin, chitosan, fibrinogen and thrombin. Further inclusion of a biocompatible polymeric base, particularly an alignate, generates a composition with superior and broad spectrum hemostatic capabilities, including the ability to arrest arterial hemorrhage. The invention further provides methods of using the inventive compositions in to reduce or stop bleeding, as well as a variety of apparatuses useful in hemostatic contexts that incorporate the inventive compositions. In one particular embodiment, the invention provides hemostatic dressings in which a polymeric layer incorporating chamomile, nettle, kaolin, chitosan, fibrinogen and thrombin components is applied to a textile or fabric material, for example a non-woven viscose.
