Hybrid Tissue Scaffold for Tissue Engineering: 8,815,594

A hybrid tissue scaffold is provided which comprises a porous primary scaffold having a plurality of pores and a porous secondary scaffold having a plurality of pores, wherein the secondary scaffold resides in the pores of the primary scaffold to provide a hybrid scaffold. The pores of the porous primary scaffold may have a pore size in a range of 0.50 mm to 5.0 mm, and the pores of the porous secondary scaffold may have a pore size in a range of 50 .mu.m to 600 .mu.m. The primary scaffold may provide 5% to 30% of a volume of the hybrid scaffold.
