Patents by Inventor Barry L. Eppley

Barry L. Eppley has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7138442
    Abstract: A bone cement having a dry component including a large constituent and a small constituent. The small constituent fills a substantial volume of the interstitial spaces between the particles of the large constituent. Therefore, only a second or minor interstitial space is left remaining between the individual particles of the small constituent and the particles of the small constituent and the particles of the large constituent. Therefore, a reduced amount of a polymerizable component need be added to the dry component to form a bone cement. Such a bone cement formulation decreases the exothermic temperature of the bone cement and decreases the possibility of tissue necrosis in the implantation area.
    Type: Grant

  • Patent number: 6187044
    Abstract: Compositions and methods are disclosed for filling prostheses for implantation into human soft tissue. The compositions comprise at least one nonionic surfactant, such as a polysorbate, which can be provided to fill a physiologically compatible shell or containment sac of the prosthesis. The liquid compositions of the present invention have a relatively high viscosity and are quickly absorbed from body tissues, metabolized and excreted with no known adverse effect. The compositions can be injected into the physiologically compatible shell either before, during or after the surgical implantation procedure.

  • Patent number: 5916200
    Abstract: The invention relates to an apparatus and method for stabilization of a shunt relative to a bone. The apparatus includes a body member and a plurality of attachment members forming a part of the body member. Each of the attachment members are operable to receive a bone screw so as to secure the body member to the bone. A plurality of movable fingers are movably attached to the body member. The plurality of movable fingers are adapted to engage and stabilize various size shunts relative to the bone.

  • Patent number: 5569250
    Abstract: A biocompatible osteosynthesis plate operable for being enhanced in a substantially secured relation to a plurality of adjacent bone portions is provided. The biocompatible osteosynthesis plate includes an elongated section having a top face and a bottom face, at least one fastener opening disposed between the top face and the bottom face, and means disposed upon elongated section to permit the formation of additional fastener openings therethrough during a surgical procedure. The osteosynthesis plate is in a first configuration at a first thermochemical state and is operable to be converted to a second thermochemical state so that it may be deformed prior to fixation. The osteosynthesis plate may further include means disposed upon the elongated section for enhancing structural rigidity, which may be provided as one or more raised surfaces, or rails, disposed upon the top face of the osteosynthesis plate.

  • Patent number: 5092883
    Abstract: A material with chemically induced surface charges is employed to foster formation of mammalian hard and soft connective tissues. The material may be in the form of beads such as ion exchange resins. Bead materials with a negative surface charge stimulate formation of hard tissue within long bones and foster bony repair of defects in parietal bones and in mandibular rami. Beads with positively charged surfaces engender formation of large quantities of soft dense connective tissue when implanted into defects in the cranium or when used as an onlay on the nasal bone surface. The use of such beads or other charged biodegradable materials and the use of other surface charged materials with different physical configurations provides significant improvement in hard and soft connective tissue repair, augmentation and replacement in medical fields such as orthopaedic and maxillofacial surgery.
