Patent ID: 8481066

Claim:
A three-dimensional scaffold with interconnected pores for repair of tissue comprising: a scaffold body for structural support of the tissue scaffold comprising: scaffold body components bonded to each other to define the scaffold body and provide a scaffold body compressive strength of greater than 0.4 MPa, wherein the scaffold body components are of a component material comprising, by weight %: B 2 O 3 50 to 90 Na 2 O 0 to 25 Li 2 O 0 to 25 K 2 O 0 to 25 Rb 2 O 0 to 25 CaO 0 to 40 MgO 0 to 25 SrO 0 to 40 BaO 0 to 50 P 2 O 5 0 to 10 SiO 2 0 to 18 Al 2 O 3 0 to 3 F 0 to 4 transition metal elements 0 to 10 cumulative; wherein the component material comprises two or more oxides from among Li 2 O, Na 2 O, K 2 O, and Rb 2 O in a cumulative concentration between 5 and 25 wt % and two or more oxides from among MgO, SrO, BaO, and CaO in a cumulative concentration between 1 and 45 wt %, wherein the scaffold body has a porosity between about 15 and about 90 vol %, and wherein less than 5 wt % of the component material is crystalline material; wherein the component material comprises less than 0.5 wt % Ca.
