ClotFoam is a sealant and hemostatic agent for use in cases of non-compressible hemorrhage for moderate to severe bleeding. It can be applied in the operating room through laparoscopic ports, or directly over lacerated tissue in laparotomy procedures or outside the operating room through a mixing needle and/or a spray injection method following intracavitary severe trauma or surgery. Its crosslinking technology generates an adhesive scaffold that carries a fibrin sealant required for hemostasis. Clotfoam produces a foam that spreads throughout a body cavity reaching the lacerated tissue to seal tissue and promote the coagulation cascade. The composition is biocompatible and non-inflammatory.The invention uses fibrin monomer polymerized by a change of pH as active sealing component. The viscoelastic properties of the foam as well as the rapid formation of a fibrin clot ensure that the sealant remains at the site of application without being washed away by blood.
