Abstract: An implant with anti-inflammatory or antibacterial effects, or both, for implantation in a human or animal body, the implant having a set of porous grains or granules, wherein at least a plurality of the porous grains or granules include titanium, one or more titanium oxides or titanium alloy and have a titanium oxide layer on their surface and have a mean length from one side to the opposite side, through a geometrical center, of at least 200 ?m and up to 5 mm and a mean specific surface area of at least 0.15 m2/g according to the BET method. Also featured is a population of grains or granules having anti-inflammatory or antibacterial effects, or both. Further featured is a method of producing an implant, a method for deriving a population of grains or granules, and a method for treating a condition with a porous grain or granule.

Abstract: The present invention refers to a method for treatment of an inflammatory and/or bacterial condition, wherein particles of microstructure comprising titanium, titanium alloy, at least one titanium oxide or a combination thereof, and having a surface with at least a substantial part consisting of at least one type of titanium oxide, are brought into contact with at least one infected site in a human or animal body by insertion, injection or implantation, which at least one infected site exhibits the inflammatory and/or bacterial condition. Moreover, the present invention refers to an injectable suspension comprising the particles according to the invention and a fluid vehicle for use as a medicament. Finally, the present invention also defines use of the particles of microstructure according to the invention for the manufacture of a medicament in the form of an injectable suspension.
Abstract: The present invention relates to an irregularly shaped grain for providing ingrowth and growth of connective tissue as well as growth of other cell types leading to cluster of cells, tissues and parts of organs. Said grain includes multiple pores that are continuous through said grain, and openings of said multiple pores and ducts or passages interconnecting at least a portion of said multiple pores have a width of greater than about 10 ?m. Said grain is preferably a metal or metal alloy. The invention also relates to different applications of the grains.
Abstract: A body, such as a grain, for providing ingrowth and growth of bone tissue and/or connective tissue. The body consists of a plastic or non-essentially elastic biocompatible material, preferably metal or metal alloy. It is also porous, having the following porosity characteristics: (a) the porosity is continuous and (b) the opening of cavities/indentations/pockets and the ducts connecting them has the width of >about 50 ?m for bone tissue and >about 10 ?m for connective tissue. In a method of making such a body, the body has been produced by blowing gas into a melt of metal. An advantageous use of bodies according to the invention is enclosing thereof in a casing, formed with openings, for making an implant, such as a spinal implant.
