Abstract
The present specification discloses porous materials, methods of forming such porous materials, materials and devices comprising such porous materials, and methods of making such materials and devices.
Claims21
A method for forming an elastic, porous structure suitable for implantation in a mammal, the method comprising the steps of:
- a) coating porogens with a matrix material base to form a matrix material-coated porogen mixture;
- b) filtering the matrix material-coated porogen mixture through a sieve to remove excess matrix material;
- c) pouring the filtered mixture into a mold;
- d) treating the filtered mixture to form a scaffold comprising fused porogens and cured matrix material, wherein the scaffold comprises a three-dimensional structure in the form of the mold;
- and
- e) removing the fused porogens from the scaffold, wherein fused porogen removal results in a porous material comprising the cured matrix material defining an array of interconnected pores.
