  • Patent number: 8567162
    Abstract: The present disclosure relates to a dynamic bioactive bone graft material and a method of handling the material to prepare an implant. In one embodiment, a method of preparing a dynamic bioactive bone graft implant is provided. The method includes the step of providing a porous, fibrous composition of bioactive glass fibers, wherein the fibers are characterized by fiber diameters ranging from about 5 nanometers to about 100 micrometers, and wherein the porosity of the matrix ranges from about 100 nanometers to about 1 millimeter. The porous, fibrous composition is introduced into a mold tray, and a shaped implant is created using the mold tray. The composition may be wetted with a fluid such as saline or a naturally occurring body fluid like blood prior to creating the shaped implant. In another embodiment, the porous, fibrous composition is provided with the mold tray as a kit.

  • Patent number: 4487371
    Abstract: A novel comminution apparatus and method for comminuting a granular feed into a product having a predetermined particle size. The comminution apparatus includes a high-speed cutter member operating inside a screen enclosure having adjustable openings in the screen enclosure. A lever arm is used to adjust the relative openings between an inner screen and an outer screen of the screen enclosure with the size of the openings in the screen enclosure predetermining the particle size range passing therethrough. Rotation of the cutter member creates an air flow outwardly through the screen enclosure while an air recycle system directs the airflow across the outlet to a feed hopper to carry the particulate feed into contact with the cutter assembly.
