System and method for pressure mixing bone filling material

摘要

A method for treating a vertebral bone comprises providing a bone filling material and mixing the bone filling material in a vessel to form a bone augmentation material. The method further comprises pressurizing the vessel with a pressurization source to retain a plurality of voids within the bone augmentation material. The method further includes inserting a material delivery device into the vertebral bone and injecting the bone augmentation material with the retained plurality of voids from the material delivery device and into the vertebral bone.

1. A method for treating a vertebral bone comprising:
providing a bone filling material; mixing the bone filling material in a vessel to form a bone augmentation material comprising an osteoinductive material; pressurizing the vessel with a pressurization source to retain a plurality of voids within the bone augmentation material while the bone augmentation material is in the vessel; inserting a material delivery device into the vertebral bone; injecting the bone augmentation material with the retained plurality of voids from the material delivery device and into the vertebral bone, and each of the plurality of voids is between 1 and 2000 microns in diameter, wherein the step of mixing and the step of pressurizing occur simultaneously.
