Claims26
An implantable device for promoting tissue ingrowth therein comprising:
- a reticulated, resiliently-compressible, elastomeric matrix comprising a continuous network of solid structures defining a void space therein, wherein said void space comprises a plurality of interconnected pores forming a continuous network of intercommunicating passageways extending from an interior portion to an exterior surface of said matrix,
- wherein said matrix comprises a biocompatible, cross-linked polycarbonate polyurethane-urea formed by a reaction of a mixture comprising:
- (i) a polycarbonate polyol, and
- (ii) an isocyanate component comprising at least about 5% by weight of said isocyanate component of 2,4′-diphenylmethane diisocyanate, and
- wherein said matrix is substantially free of isocyanurate linkages.
