Compositions, systems, methods, etc., related to fucan-dendrimer complexes wherein a fucan molecule is linked or otherwise attached to a dendrimer. For example, the current compositions can comprise fucan covalently linked, conjugated, attached, tagged, adducted, bound, etc., to a dendrimer. These fucan-dendrimer complexes include fucan-hyperbranched polyglycerol, fucan-hyperbranched poly(glycerol ester), fucan-hyperbranched poly(1,3-diether), fucan-poly(3-ethyl-3-(hydroxymethyl)oxetane), fucan-hyperbranched polyesters, fucan-hyperbranched polyethylene, fucan-hyperbranched polystyrene, fucan-hyperbranched poly(urea-urethanes), fucan-hyperbranched polyethyleneimine, fucan-hyperbranched poly(amido amine)s, fucan-hyperbranched polyphosphates, fucan-hyperbranched polypeptides, fucan-hyperbranched polysaccharides, fucan-hyperbranched polyacrylates and fucan-hyperbranched beta-cyclodextrin. These fucan-dendrimer complexes may be used in medically and/or pharmaceutically effective compositions, for a plurality of applications, including the treatment of fibrous adhesions. In some embodiments, the fucan is fucoidan.
