  • Patent number: 6579537
    Abstract: A method of producing a pharmaceutical preparation comprising fibronectin and fibrinogen is disclosed. The method involves admixing into a starting solution of fibrinogen and fibronectin, in a single step, a precipitating composition comprising a polyalkylene glycol and at least one of glycine and &bgr;-alanine which forms a precipitate. Next, the precipitate is collected and a pharmaceutical preparation is prepared from the precipitate. The pharmaceutical preparation has a fibronectin:fibrinogen ratio from about 0.02 to about 0.2.

  • Patent number: 5962405
    Abstract: The invention relates to storage-stable fibrinogen preparations for preparing concentrated fibrinogen solution for use as a tissue adhesive or for preparing fibrinogen solutions for other uses, for example, for infusion purposes. The fibrinogen preparations are characterized in that(i) the lyophilized preparation comprises a substance improving the solubility of fibrinogen such that the reconstitution time is up to 15 minutes, preferably less than 7 minutes, when dissolving with water at room temperature to a solution with a fibrinogen concentration of at least 70 mg/ml and(ii) the ready-to-use tissue adhesive solution obtained from the preparation forms fibrin clots having physiological fibrin structure after mixing with a thrombin-CaCl.sub.2 solution.

  • Patent number: 4735616
    Abstract: An arrangement for applying a tissue adhesive based on human or animal proteins, to seamlessly or seam-supportingly connect human or animal tissue or organ parts by uniting with blood-clot-promoting coagulation factors (thrombin). The arrangement includes a plurality of syringe bodies commonly actuatable by pistons and to which a connecting head is attachable. The syringe bodies have equal effective strokes, yet one of them, i.e., that destined to contain the protein solution, has a cross sectional area that is two to nine times larger than the other one(s). There may be applied tissue adhesives having a fibrinogen content of from 2 to 12%.
