  • Patent number: 8372157
    Abstract: An osteoconductive backing implant for joint revisions is provided that may enhance bone healing and, for cementless implants, bony integration of the implant. The backing implant comprises a generally planar surface that may be formed into a generally hemispherical shape. In one embodiment, the backing implant comprises a disc having an inner hole and an outer edge, at least one slit extending from the inner hole to the outer edge. The disc may be formed from a coherent mass of elongate, mechanically entangled demineralized bone particles.

  • Patent number: 8323700
    Abstract: The present invention relates to a method for making bone particles from bone of a variety of sizes and a workpiece forming and holding device for use with the method. The workpiece forming device includes a base and a base frame attached to the surface of the base. An apparatus for forming a solidified mass of bone and immobilization medium is also provided which includes the workpiece forming device and a detachable former member enclosing the base frame. Bone is immersed in an immobilization medium within such workpiece forming device, which is solidified to form a solidified mass of bone and immobilization medium and then subdivided to provide particles of bone in association to with immobilization medium. The immobilization medium may be optionally removed to leave bone particles suitable for use in orthopedic applications including implants.

  • Patent number: 4073776
    Abstract: A tackifier system which includes the reaction product of oxirane bearing materials with alkyl phenol novolacs for elastomers of alpha-olefin polymers which are sulfur curable.The invention is directed to reaction products of alkyl phenol novolacs with oxirane bearing materials. The reaction products of alkyl phenol novolacs with oxirane bearing materials have been found to be excellent tackifiers for various types of elastomers.Further, the invention is directed to elastomer compositions containing reaction products of alkyl phenol novolacs with oxirane bearing materials. Elastomer compositions containing the reaction products of alkyl phenol novolac resins with oxirane bearing materials exhibit excellent tack properties.Tackifiers are employed in elastomeric compositions to produce wider practical ranges of elastomer properties, such as stiffness and tack. Tackifiers are used to improve adhesion, and sometimes cohesion without necessarily stiffening or softening the elastomer composition.

  • Patent number: RE29157
    Abstract: Superior polychloroprene adehsives are prepared by incorporating the reaction product of an alkali catalyzed alkyl phenol-formaldehyde resin and zinc resinate. Preferably an arylphenol and/or bisphenol A is also incorporated. Also preferably rosin is included in the composition. Other zinc compounds, e.g. zinc oxide, zinc borate, zinc phosphate, zinc carbonate, and zinc salicylate can be used in place of zinc resinate.
