At least partially resorbable reticulated elastomeric matrix elements and methods of making same
First Claim
1. A matrix comprising a biocompatible, cross-linked, biodegradable, elastomeric polyurethane, the matrix having a continuous-interconnected void phase, wherein the matrix is configured to be implantable in a human body and to support a biological tissue in-growth, wherein the matrix comprises a biodegradable, polyol-derived soft segment and an isocyanate-derived hard segment, and wherein said matrix is reticulated, wherein the continuous-interconnected void phase extends from an interior portion to an exterior surface of said matrix;
- wherein a path through the void phase can be drawn in a substantially linear direction across an entirely of said matrix beginning at any portion of an exterior surface of said matrix containing said void phase.

28. A matrix comprising a biocompatible, cross-linked, biodegradable, elastomeric polyurethane, the matrix having a continuous-interconnected void phase, wherein the matrix is configured to be implantable in a human body and to support a biological tissue in-growth, wherein the matrix comprises a biodegradable, polyol-derived soft segment and an isocyanate-derived hard segment, and wherein said matrix is reticulated, wherein said isocyanate hard segment is substantially non-crystalline;
- wherein a path through the void phase can be drawn in a substantially linear direction across an entirely of said matrix beginning at any portion of an exterior surface of said matrix containing said void phase.
