Abstract
A glass, glass-ceramic, or ceramic bead is described, with an internal porous scaffold microstructure that is surrounded by an amorphous shield. The shield serves to protect the internal porous microstructure of the shield while increasing the overall strength of the porous microstructure and improve the flowability of the beads either by themselves or in devices such as biologically degradable putty that would be used in bone or soft tissue augmentation or regeneration. The open porosity present inside the bead will allow for enhanced degradability in-vivo as compared to solid particles or spheres and also promote the growth of tissues including but not limited to all types of bone, soft tissue, blood vessels, and nerves.
Claims8
A shielded glass scaffold comprising
- sintered 45S5 bioactive glass fibers and 45S5 bioactive glass beads, some of the fibers and beads being bonded to one another to create a sintered, porous agglomerate having a melted and then cooled shield of fused glass about the sintered agglomerate, thereby forming the shielded glass scaffold.
A glass scaffold comprising sintered fibers and sintered beads formed from two or more different glass compositions and being a sintered agglomerate with a melted and cooled shield of fused glass about the sintered agglomerate.
