  • Publication number: 20080194729
    Abstract: The invention relates to a novel bioactive and osteoconductive bone cement and a method for producing the same from polyacrylates or polymethylacrylates by addition of small amounts of polymerizable monomers containing anionic groups which cause the cement surface to mineralize after being incubated in simulated body fluid and in which the obtained mineralized layers contain calcium phosphate phases such that the formation of fibrous intermediate layers is prevented once the bone cement has been implanted in bones. Optionally, other additives, e.g. biocompatible calcium salts, and/or biocompatible buffering substances, or x-ray contrast agents, antibiotics, antimicrobial agents, and/or anti-inflammatory agents can be added in order to improve the properties of the cement for individual purposes.

  • Publication number: 20060275339
    Abstract: The invention concerns the use of polyhexamethylene biguanide in PMMA bone cements, which preferably do not contain antibiotics. The cements exhibit a concentration of active principle not exceeding 1 wt. % relative to the total weight of the cement, which is a concentration sufficiently high to prevent microbial colonization of the cement surface. The cements do not cause durable alteration of the healing process.

  • Publication number: 20050111300
    Abstract: A device for the storage, mixing and discharge of liquid and pulverulent materials for medical use has a mixing cylinder (1), a perforated mixing plunger (8), which is axially and rotatably movable in the mixing cylinder (1) by means of an actuation rod (9), an axially displaceable discharge plunger (4), a sealable discharge aperture (3) in the mixing cylinder (1) and means for actuation of the discharge plunger (4). The discharge plunger (4) has in its interior a sealable storage chamber (14) for the accommodation of one of the materials to be mixed, so that pre-packaged amounts of the materials to be mixed can be introduced separately into the device, even without packaging, and stored over an extended period. The discharge plunger (4) engages with the mixing cylinder (1) via an actuation thread, so that rotation of the discharge plunger (4) relative to the mixing cylinder (1) enables discharge of the mixed materials.

  • Publication number: 20050079198
    Abstract: The invention describes an article made from chitosan-coated metal, where an impermeable chitosan layer having a barrier action is present on the metal through electrochemical polarisation in a chitosan-containing solution. The incorporation of biologically active components into the chitosan coating enables the coating to be matched to various applications and the bio-compatibility of correspondingly modified surfaces to be increased. Metallic articles or surfaces coated in this way are used, for example, as material for medical implants.
