Abstract: The present invention is directed to a powder delivery system containing a composition comprising gelatine or collagen powder having a mean particle size of at least 10 ?m. The gelatine or collagen powder is typically in dry form, i.e. no liquid components and/or propellants are added to the composition. The present invention is also directed to an improved powder delivery system which contains a protective structure, such as a skirt, located close to the orifice of the delivery system. In a further aspect, the present invention is directed to gelatine- or collagen-based compositions useful in haemostatic applications. In a further aspect of the invention the powder delivery system comprises gelatine or collagen powder in a dry form ready to use. Further the powder delivery system in a dry form might comprise an agent incompatible with moisture and/or water.

Abstract: The present invention relates to a haemostatic composition comprising a biologically absorbable material and hyaluronic acid or a derivative thereof, methods of producing such compositions and the use of these compositions. In particular the method of producing said haemostatic composition comprises treating it with dry heat at a temperature between 110-200° C.
