Beschreibung
Zusammenfassung:	Hemostatic foams Abstract The invention is directed to hemostatic foams and to the preparation of such foams. In a first aspect, the present invention provides a biodegradable hemostatic foam comprising a polymer blend of a water-soluble polymer and a phase-separated polyurethane comprising an amorphous segment and a crystalline segment, wherein at least said amorphous segment comprises a hydrophilic segment. L'invention porte sur des mousses hémostatiques et sur la préparation de telles mousses. Dans un premier aspect, la présente invention fournit une mousse hémostatique biodégradable comprenant un mélange de polymères constitué d'un polymère hydrosoluble et d'un polyuréthane à phases séparées comprenant un segment amorphe et un segment cristallin, au moins ledit segment amorphe comprenant un segment hydrophile.
