Methods of making concentrated fibrinogen containing compositions and associated systems for preparing fibrin glue

摘要

The present invention is drawn to concentrated fibrinogen compositions and associate methods and use thereof. The concentrated fibrinogen compositions can be produced by adding a sufficient amount of a cationic agent, such as protamine, to a fibrinogen containing fluid to cause the fibrinogen to form a fibrinogen precipitate; collecting the fibrinogen precipitate by a collection means, such as centrifugation; and suspending or solubilizing the fibrinogen precipitate in a liquid vehicle to form a concentrated fibrinogen composition. The concentrated fibrinogen compositions can be incorporated into systems for making fibrin glues and be used in treating wounds.
