1. A porous material comprising a substantially non-degradable, biocompatible elastomer matrix defining an array of interconnected pores, the matrix made by the steps ofa) fusing porogens to form a porogen scaffold comprising fused porogens;
- b) coating the porogen scaffold with an elastomer base to form an elastomer coated porogen scaffold;
c) curing the elastomer coated porogen scaffold; and
d) removing the porogen scaffold, wherein porogen scaffold removal results in a porous material, the porous material comprising a substantially non-degradable, biocompatible, elastomer matrix defining an array of interconnected pores.

9. A porous material made by a process comprising the steps of:
-
a) fusing porogens to form a porogen scaffold comprising fused porogens;
wherein substantially all the fused porogens are each connected to at least two other fused porogens, and wherein the diameter of substantially all the connections between each fused porogen in between about 15% to about 99% of the mean porogen diameter;b) coating the porogen scaffold with an elastomer base to form an elastomer coated porogen scaffold; c) curing the elastomer coated porogen scaffold; and d) removing the porogen scaffold from the cured elastomer, wherein porogen scaffold removal results in a porous material, the porous material comprising a three-dimensional, substantially non-degradable, biocompatible, elastomer matrix defining an array of interconnected pores. - View Dependent Claims (10, 11, 12)
