    摘要: There is provided an implant retaining device, which has the effect of preventing an intervertebral implant from jutting out of the receiving bed. The implant retaining device generally includes a plate having at least one throughbore to receive a screw, and a screw for securing the plate to the vertebrae. The plate may be dimensioned to cover a portion of the opening of a receiving bed, and thus, need only be secured to a single vertebral body. In an alternate embodiment, the plate may be used during bone fracture correction procedures to prevent a bone screw from backing out of engagement with adjacent bone sections. A method of retaining an intervertebral implant using the device is also provided.

    摘要: An interference screw suitable for surgical use is provided. The interference screw is constructed from bone and includes an elongated body having an outer threaded surface, a tapered insertion end and a central throughbore. Insertion tool engaging structure is formed along the walls defining the throughbore. The insertion tool engaging structure extends from the proximal end of the elongated body over a substantial portion of the length of the elongated body. The insertion tool engaging structure functions to distribute the forces required to insert the interference screw throughout the body of the interference screw to prevent fracturing of the interference screw during insertion into bone.

    摘要: A process for producing spherical, non-porous hydroxyapatite particles having a size which does not exceed 250 microns and having a density of at least 3.00 g/cc. The process comprises agglomerating in the presence of water as the only additive hydoxyapatite powder feedstock having a purity of at least 97%, and having metallic impurities which do not exceed 500 ppm, to form hydroxyapatite particles having a size which does not exceed 350 microns. The particles are then dried and then sintered at a temperature from about 1,100.degree. C. to about 1,200.degree. C. to provide spherical, non-porous hydoxyapatite particles which do not exceed 250 microns and having a density of at least 3.00 g/cc. Such particles have a variety of medical uses, including bone replacement, implant coatings, and dental applications such as alveolar ridge augmentation, root extraction site fillings, restoration of periodontal osseous lesions, and soft tissue augmentations.

    摘要: An interconnect connects a vial to a syringe for the transfer of material to the syringe or back to the vial. The interconnect includes a vial connecting mechanism and a tapered sleeve to receive the syringe. A metering port allows control of the material transfer rate and prevents partial transfers which could cause material spillage.

    摘要: Perfluorination of 2,2,4,4-tetramethylpentane by direct fluorination with F.sub.2 or like reagents at low temperature, using inert gaseous diluents, yields a mixture of perfluoro 2,2,4,4-tetramethylpentane and 3-hydro-nonadecafluoro 2,2,4,4-tetramethylpentane together with lesser amounts of 3,3-dihydro-octadecafluoro 2,2,4,4-tetramethylpentane. The perfluoro and nonadecafluoro-tetramethylpentane mixture is useful in synthetic blood substitute compositions.
