Abstract: A malleable polysaccharide soft tissue filler for filling tissue cavities or voids such as those resulting from tumor removal or other tissue resection. The soft tissue filler includes a first cross-linking polysaccharide, preferably a beta-D glucan, and a second cross-linking polysaccharide. The soft tissue filler is both porous and malleable and can be formed to accommodate the tissue cavity or void. The soft tissue filler can include an embedded marker for locating on medical imaging. Methods of making the soft tissue filler including lyophilizing an aqueous polysaccharide suspension are disclosed. The second cross-linking polysaccharide provides for increased structural integrity in a high-porosity and malleable soft tissue filler in which the respective cross-linking polysaccharides synergistically provide structural scaffolding for one another. Methods of use are also disclosed.
