    摘要: A method of manufacturing an osteoinductive osteoimplant is provided which comprises the steps of: demineralizing part or all of at least one surface of a monolithic section of cortical bone to a depth of at least about 100 microns; and, configuring the monolithic section of cortical bone to provide an osteoimplant possessing an outer surface possessing at least one demineralized zone and a non-demineralized zone. An implant produced according to the above method demonstrates improved osteoinduction without producing any clinically significant reduction of strength in critical regions of the osteoimplant.

    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.
