Abstract
Heteromorphic sponges are described which have matrix structures with oriented substructures added to facilitate cellular invasion. A sponge may be used as a wound implant by cutting it to the shape of a wound bed and placing therein. The matrix structure provides conduits which assist invasion of the sponge by cells which degrade the sponge and lay down new tissue to replace it. The incorporation of active agents in the matrix and/or substructures enhances wound healing.
