METHOD FOR OBTAINING GRADED PORE STRUCTURE IN SCAFFOLDS FOR TISSUES AND BONE, AND SCAFFOLDS WITH GRADED PORE STRUCTURE FOR TISSUE AND BONE

摘要

A scaffold for at least one of: tissue regeneration and bone growth, the scaffold being fabricated from at least two polymers, the polymers being of differing rates of bio degradability. A first of the at least two polymers is able to be leached by a solvent, and all other polymers of the at least two polymers being either inert to the solvent or having a lower dissolution rate in the solvent. The scaffold has a graded porosity with high porosity at a surface of the scaffold, and low porosity at a core of the scaffold.
