  • Patent number: 9957311
    Abstract: Surface-binding peptides have the capability of binding to surfaces of biocompatible materials and can thereby be used to immobilize various heterologous molecules of interest onto the surface. This means that surfaces of, for instance, implants and implantable medical devices can be tailored to present various characteristics by immobilizing selected heterologous molecules of interest on the surfaces of the implants and implantable medical devices. The surface-binding peptides consist of 5-17 consecutive amino acids of an extended beta-hairpin motif EIIATMKKKGEKRCLNP (SEQ ID NO: 57) in Interferon gamma-induced protein 10 (IP-10).

  • Patent number: 8784845
    Abstract: The present invention teaches the use of a metal or an oxide of a metal having a capability of reducing the amount of the chemokine IP-IO in a sample and/or reducing the production of IP-IO in cells. The metal is a metal of group 4 or 5 in the periodic table of the elements and preferably titanium. These metals and metal oxides can selectively bind IP-IO to its surface to thereby scavenge IP-IO from the surrounding medium. In addition, a metal-cell contact induces a reduction in the production of IP-IO from IP-IO producing cells. The metals and metal oxides of the present invention can therefore be used for treating and/or preventing medical conditions characterized by adverse IP-IO expression, such as inflammatory reactions.

  • Patent number: 7955613
    Abstract: A bioartificial implant comprises a semipermeable barrier designed from one side to allow diffusion or prevent diffusion of predetermined substances/materials/molecules/cells/cell lines produced in the human body to the other opposite side of the barrier, and from said other opposite side to allow diffusion or prevent diffusion of predetermined substances which are the same as or different from the first mentioned substances/materials/molecules/cells/cell lines. The semipermeable barrier has a surface coating at least on said one side a bioactive metal, such as titanium, which surface coating is permeable to allow said diffusions. In a method for reducing the risk of formation/growth of connective tissue in connection with an implant which comprises a semipermeable barrier, the barrier is provided at least on one side with a permeable coating of bioactive metal. An example of the use of the implant is bioartificial pancreas.

  • Publication number: 20080188857
    Abstract: In a method and a device for improving the fixing of an elongate prosthesis in a bone cavity, said fixing being provided by a bed in which the prosthesis has been driven down by vibration, a ring of a flexible, essentially plastic material is arranged around the proximal part of the prosthesis so that the ring fills the space between the bone wall and the prosthesis, whereupon the ring is compacted and compressed, after which strokes are made on the prosthesis in its longitudinal direction for final fixing thereof in the bed. The ring significantly improves the strength of the prosthesis in the bed.

    Abstract: A method and an insertion unit for inserting an elongate prosthesis into a prosthesis fixing device. This device comprises a bed of grains and biocompatible material, and a vibrating tool is used for insertion, the vibration head of which performs an oscillating motion back and forth about a swivelling axis (3?). According to the invention, said axis (3r) of the vibrating tool essentially coincides with the longitudinal axis (I1) of the elongate prosthesis (1). The method and the insertion unit provide a prosthesis fixing device consisting of said bed, in which the grains are evenly packed along the length of the prosthesis.
