Abstract

The present invention includes both sterilized and unsterilized hemostatic compositions that contain a continuous, biocompatible liquid phase having a solid phase of particles of a biocompatible polymer suitable for use in hemostasis and which is substantially insoluble in the liquid phase, and a discontinuous, biocompatible gaseous phase, each of which is substantially homogenously dispersed throughout the continuous liquid phase, methods for making such compositions, medical devices that contain sterilized hemostatic compositions disposed therein and methods of making such devices.
