Abstract: A porous, self-sustaining body useful as a scaffold for bone grafting is provided. The scaffold comprises a carbonaceous matrix comprising a continuous phase having a surface and defining a plurality of open spaces throughout the matrix. The internal and external surfaces of the matrix are coated with a layer or film selected from the group consisting of osteogenic materials, therapeutic agents, and combinations thereof. The porous body comprises organic materials and is substantially free of metals. Methods of making and using the porous self-sustaining body are also provided, along with kits for facilitating the same.

Abstract: An intervertebral implant for placement in the intervertebral space between two adjacent vertebral bodies is provided. The implant comprises a hollow cage and a porous core received within the cage. The cage comprises a superior surface configured to contact a first vertebral body, an inferior surface configured to contact a second vertebral body, and an outer wall extending between the superior surface and inferior surface. The outer wall comprises an exterior surface defining the outer perimeter of the implant, and an interior surface defining an inner (hollow) space or void. The porous core is received within the inner space or void, and preferably fills the void. The core comprises a carbonaceous matrix comprising a continuous phase having a surface and defining a plurality of open spaces throughout said matrix. Suitable carbonaceous matrices are selected from the group consisting of carbon foam, graphite foam, and combinations thereof.

Abstract: A radiolucent surgical instrument comprising an internal stiffener composed of a first composite material having a first modulus and an overmold component formed around at least a portion of the internal stiffener and composed of a second composite material having a second modulus. The first modulus may be greater than the second modulus. The overmold component may be formed around the internal stiffener via injection molding. The internal stiffener may be a structural laminate fabricated by composite ply lay-up and cure and may have a bending stiffness between approximately 10 MSI and 16 MSI. The overmold component may be a short fiber reinforced thermoplastic form and may have a non-uniform distribution of thickness. The surgical instrument may include, for example, retractors, forceps, elevators, dissectors, suction tubes, drill guides, or separators.
