  • Publication number: 20040170664
    Abstract: Injured nerves are reconnected and regenerated by inserting injured nerve ends into a collagen tube having an outer compact smooth barrier surface preventing ingrowth of connective tissue, avoiding formation of scar tissue and allowing for unimpaired healing of injured nerves. The tube has an inner fibrous surface opposite the outer smooth barrier surface. The soft fibrous inner surface of the tube facilitates nerve growth promotion.

  • Patent number: 6641571
    Abstract: Patients undergoing cardiopulmonary bypass surgery are treated perioperatively with methylol transfer agents, such as Taurolidine. Patients undergoing crystalloid cardioplegia who are treated with taurolidine show reduced levels of IL-6 and increased levels of IL-10 when compared to crystalloid cardioplegia patients administered a placebo. Crystalloid cardioplegia patients administered Taurolidine also show reduced levels of IL-6 and increased levels of IL-10 when compared to blood cardioplegia patients who were administered Taurolidine.

  • Patent number: 6482240
    Abstract: Collagen membranes are formed from porcine rinds (i.e., pig skins) for us in a variety of applications and, most preferably, for wrapping food products, such as hams and the like. First, after removing skins from the porcine, the skins are promptly frozen. In later processing, the rinds are thawed and then enzymatically defatted. Then, a quick alkalinic hydrolyzation is performed on the rinds. Then, an acidic hydrolyzation is performed on the rinds. The rinds are then ground into a gel-like fluid mass. Finally, the fluid mass is extruded, sheeted and dried into a collagen membrane. The collagen membrane produced can be, in preferred embodiments, used for wrapping food products, such as hams.
