Abstract: A method and a device for treating at least a part of an individual's skin having a natural first polarization state. The method comprises the steps of applying at least two electrodes on the individual's skin at a distance from each other, and supplying a direct current to said electrodes to form an electrical potential difference between said electrodes on said part of the skin in order to bringing said part of the skin into a second polarization state, which is different from the first. The part of the skin is then suitable subjected to further treatment for example using cosmetics or pharmaceuticals. The invention can be utilized in the field of cosmetics and for therapy, and it can be used e.g. for accelerating skin care processes.

Abstract: Porous bioabsorbable, bioactive and load-bearing composite medical device structure includes a plurality of regular textile planar layers (1a, 1b . . . ) formed of continuous bioabsorbable polymer matrix and bioceramic fibers acting as reinforcements, both included in continuous fibrous elements (3) forming the textile layers. The layers are placed on top of each other to form a structure having two dimensions (x, y) at right angles to each other according to the two dimensions of the textile layer and a third dimension (z) perpendicular to them and resulting from the piling of the layers. A plurality of passages extend through the layers as a result of the openings (2) defined by portions of the continuous fibrous elements (3) extending substantially in the direction of the plane.

Abstract: A bioabsorbable implant or its part consists of a structure having a varying characteristic in at least in one direction defining a gradient corresponding this characteristic. The structure comprises bioabsorbable polymer and another substance within or next to said bioabsorbable polymer. The structure is constituted of a wound or folded blank (1) having a direction of variation (L) of a characteristic (Ch) which is at least one of the following: concentration of the other substance, species of the other substance, type of the bioabsorbable polymer, or porosity (size of openings in the blank), said structure having a winding axis or fold lines substantially perpendicular to said direction of variation (L). This results in said varying characteristic in the structure in said at least one direction defining the gradient and traversing superposed layers formed of sections of the blank (1) that are successive in said direction of variation (L).

Abstract: A porous composite suitable for filling a recess or a through-passing hole in an implant. The composite includes particles A prepared from a bioactive material and particles B prepared from a non-bioactive material or weakly bioactive material, which is sintratable with the bioactive material, such that particles A and particles B have been sintered together to a porous composite. Particles A and particles B are essentially homogeneous in size. Also disclosed is an implant which contains a core and the composite.
