A bone graft delivery device comprising:
- a porous biodegradable graft body for inducing bone growth at a surgical site, the porous biodegradable graft body having demineralized bone matrix (DBM) fibers disposed within the porous biodegradable body, and DBM powder disposed adjacent to, on or in the DBM fibers, wherein the porous biodegradable graft body facilitates transfer of cells into and out of the porous biodegradable graft body to induce bone growth at the surgical site.
A bone graft delivery device comprising:
- a porous biodegradable graft body for inducing bone growth at a surgical site, the porous biodegradable graft body having demineralized bone matrix (DBM) fibers and DBM powder suspended in a polymer matrix that is disposed within the porous biodegradable body, wherein the porous biodegradable graft body facilitates transfer of cells into and out of the porous biodegradable graft body to induce bone growth at the surgical site.
A method of making a bone graft delivery device, the method comprising:
- adding DBM fibers to DBM powder to form a mixture;
- adding the mixture of DBM fibers and the DBM powder to a collagen slurry;
- drying the collagen slurry to form a sponge;
- and disposing the sponge within a biodegradable mesh bag.
