Claim:
1. A system for repairing a bone defect, comprising: a porous foam scaffold comprised of a shape memory polymer selected from the group consisting of poly(tert-butyl acrylate/butyl acrylate), poly-DL-lactide, and poly-DL-lactide/polyhedral oligomeric silsesquioxane that is configured for expansion in response to a first stimulus after being positioned within a bone defect; a sleeve comprised of a second shape memory polymer having reinforcing fibers therein that is configured for radial contraction in response to a second stimulus positioned around said bone defect and said porous foam; and a sheet of cells cultured on a shape memory polymer substrate to have a morphology conducive to vascularization applied to said sleeve.
