Abstract: An article includes multiple layers of polyaryletherketone (PAEK), in which each layer is composed of a continuous length of PAEK, in which the continuous length of PAEK in at least one of the layers includes an interior portion, and an exterior surface including crystalline regions, in which a crystallinity of the exterior surface is higher than a crystallinity of the interior portion. The cross-sectional area of the continuous length of PAEK is non-uniform within each layer. Each layer defines a plane, and a portion of the continuous length of PAEK in each layer extends out of the plane defined by the layer. The multiple layers of PAEK define a network of interconnected pores.

Abstract: A bone graft composition comprising a viable, osteogenic cellular material combined with a viscous cryoprotectant that includes a penetrating cryoprotective agent and a non-penetrating cryoprotective agent. The viscosity of the cryoprotectant is such that the composition is malleable, cohesive and capable of being formed into desired shapes.

Abstract: A spinal implant body 100, including a body volume 101 having an inferior portion 102A, a superior portion 102B, and a central portion 102C disposed between the inferior and superior portions 102A, 102B. The body 100 further includes a first bioactive polymer portion 117A distributed throughout body volume 101, a second bioactive ceramic portion 120A distributed throughout the body volume 101, and a third interconnected pore network portion 105A (which may be filled with a fourth fugitive portion 140A) distributed throughout the body volume 101. The central portion 102C is less porous than the inferior and superior portions 102A, 102B and the pores in the inferior portion 102A are on average larger than the pores in the central portion 102C.

Abstract: The present disclosure provides novel bone matrix (BM) materials, and methods for preparation and use of the demineralized bone matrix materials and compositions therefrom. The methods of preparation include the use of a closed-vessel demineralization system, as well as simple, easily reproducible process steps, and significantly shortened times for demineralization. These novel BM materials do not require the inclusion of carriers and/or delivery agents, or the addition of binders, and can be made in various forms, including a clay, putty, crush, powder, or gel. The novel BM compositions and methods disclosed herein may, illustratively, have applications in the medical field, such as in surgical bone graft applications, in the repair and/or regeneration of bone and bone-related tissue, and the like.

Abstract: Shaped, composite bodies are provided. One portion of the shaped bodies comprises an RPR-derived porous inorganic material, preferably a calcium phosphate. Another portion of the composite bodies is a different solid material, preferably metal, glass, ceramic or polymeric. The shaped bodies are especially suitable for orthopaedic and other surgical use.

Abstract: An apparatus for the delivery of a biological composite and a method, kit, and system for preparing a biological composite is described herein. The biological composite includes both inorganic and biological materials.

Abstract: Shaped, preferably porous, inorganic bodies are provided which are prepared from a reactive blend. In accordance with one preferred embodiment, the solution is absorbed into a porous sacrificial substrate such as a cellulose sponge. The solution-saturated substrate is heated and an oxidation-reduction reaction occurs thereby forming an inorganic solid. A shaped, inorganic body is formed in situ. Optional, but preferred additional thermal treatment of the shaped, inorganic body removes the organic substrate, leaving an inorganic body that faithfully mimics the porosity, shape, and other physical characteristics of the organic substrate. Inorganic substrates may also be used to good effect. Large varieties of shaped bodies can be prepared in accordance with other embodiments of the invention and such shapes find wide use in surgery, laboratory and industrial processes and otherwise. The invention also provides chemically and morphologically uniform powders, including those having uniformly small sizes.
