Abstract
A fluidized, injectable tissue graft composition is described. The composition comprises comminuted intestinal submucosa or protease-digested intestinal submucosa. Methods for the preparation and use of injectable tissue graft compositions are described. In preferred embodiments the tissue graft material is prepared from the intestinal submucosa comprising the tunica submucosa, the muscularis mucosa and the stratum compactum of a segment of intestinal tissue of a warm-blooded vertebrate. Effective amounts of the fluidized graft compositions can be injected to promote repair tissue defects by inducing formation of endogenous tissues.
