ABSTRACT:
A porous bioabsorbable surgical implant material is prepared by coating particles of bioabsorbable polymer with tissue ingrowth promoter. Typical bioabsorbable polymers include polymers of glycolide, lactide, caprolactone, trimethylene carbonate, dioxanone, and physical and chemical combinations thereof. The tissue ingrowth promoter can include calcium hydroxide and/or a hydrophilic coating material. The hydrophilic coating material can be bioabsorbable or non-bioabsorbable. A typical non-bioabsorbable hydrophilic coating material is polyhydroxyethyl methacrylate (PHEMA). The bioabsorbable implant material may also contain a therapeutic agent. Typical therapeutic agents include an antimicrobial agent, dye, growth factors and combinations thereof.
