  • Publication number: 20060154206
    Abstract: The invention relates to a method for treating an implant surface intended for implantation into bone tissue comprising providing fluorine/and/or fluoride on at least a part of the implant surface, and providing, on the implant surface, a microroughness having a root-mean-square roughness (Rq and/or Sq) of ?250 nm and/or comprising pores having a pore diameter of ?1 ?m and a pore depth of ?500 nm. The invention also relates to an implant comprising a surface having the above characteristics.

  • Publication number: 20050234558
    Abstract: The invention relates to a method for treating an implant surface intended for implantation into bone tissue wherein a microroughness comprising pores and peaks having a pore diameter of ?1 ?m, a pore depth of ?500 nm, and a peak width, at half the pore depth, of from 15 to 150% of the pore diameter is provided. The invention also relates to an implant comprising a surface having the above characteristics.

  • Patent number: 6486140
    Abstract: The use of chitosan and a polysaccharide immobilized thereto selected from heparin, heparan sulphate and dextran sulphate for the manufacture of an agent capable of preventing or substantially reducing undesirable adhesion of damaged tissue with adjacent or surrounding tissues in connection with wound healing; and a process for the use of such agent.
    Type: Grant
    Filed: October 5, 1999
    Date of Patent: November 26, 2002
    Assignee: Medicarb AB
    Inventors: Hans-Arne Hansson, Gunilla Johansson-Rudén, Olle Larm
  • Publication number: 20020138092
    Abstract: Use of one or more saccharides, for example one or more non-toxic mono-, di-, tri-, oligo- or polysaccharides, in the manufacture of a biocompatible glue for adhering a first structure to a surface of a second structure. The biocompatible glue can be adapted to act as a temporary glue. In this case the glue may be used to enable a medical structure to be transferred from a medical instrument onto the surface of a structure of a human or animal body, for example as in the transfer of a buffer material from the fork of a surgical stapler to a diseased lung after one or more rows of staples have been fired through the buffer material into the lung during lung volume reduction surgery for treating emphysema. The biocompatible glue can also to advantage be used to adhere or secure medical structures to a structure of a human or animal body direct, such as in the case of a patch being applied to the skin of a mammal.
