Abstract:
An implantable article comprising a dissolvable sponge derived from the mixture of chitosan, a first polysaccharide and a second polysaccharides. The polysaccharides have different number average molecular weight characteristics to enable the control of the mechanical features of the sponge.

Claim (Index 20):
A method comprising:\n (a) mixing chitosan, a first polysaccharide and a second polysaccharide to form a solution, wherein the first polysaccharide and the second polysaccharide are distinct from chitosan, the first polysaccharide and the second polysaccharide have different number average molecular weight characteristics, and the solution has a viscosity of at least 0.05 Pals at 225 l/s and at 25\u00b0 C., (b) freezing the solution, and (c) lyophilizing the frozen solution to form a dissolvable sponge, wherein the first polysaccharide and the second polysaccharide number average molecular weight characteristics are such that the dissolvable sponge exhibits a wet compression strength or a dry compression strength of at least 20 grams according to the Compression Test, and a dissolution rate of greater than or equal to 1 day according to the Dissolution Test.
