ABSTRACT:
The present invention is directed to methods of forming doubly porous devices having a first porous portion with continuously interconnected pores and a second porous portion with continuously interconnected pores utilizing at least one removable open-cell porous mold form. The mold form is made from a selected material comprising particles having predetermined sizes and shapes which is capable of forming a stable mold form under selected conditions and of being removed under selected conditions. At least one stable coating layer is molded from the mold form to define a membrane separating the first porous portion and the second porous portion of said device. Alternatively, two different materials can be molded with the mold form into a doubly porous device comprising interlocked materials.
