Patent ID: 7879107

Claim:
A method of promoting osteogenesis comprising the steps of: a) providing a composition comprising a bone endogenous material in a flow phase; b) applying said composition to a site within a patient where it is desired to synthesize new bone; c) cross-linking said bone endogenous material at the application site to transform said composition from said flow phase to a congealed phase; and d) providing a dual mode porosity system in said composition in said congealed phase, said congealed phase of said composition having a first order porosity having a mean Stokes pore diameter of 0.1-300×10 −10 meters and a second order porosity having a mean Stokes pore diameter on the order of 10 −6 meters, said first order porosity being provided in bone endogenous material comprising a material selected from the group consisting of alginates, vitrogens, vitronectins, chitosans, and mixtures thereof.
