Abstract: Copolymer-modified nanoparticles produced by a process in which nanoparticles are ablated by laser radiation from a surface of a substrate in a liquid include an amphiphilic copolymer.

Abstract: A vascular prosthesis includes a prosthesis wall whose outer surface has at least one reinforcing means, the surface of the prosthesis wall and the surface of the at least one reinforcer being coated, at least in part, with an antimicrobial layer.

Abstract: A medical device includes a porous article of expanded polytetrafluoroethylene (ePTFE) having a microstructure of nodes interconnected by fibrils, and a coating including an antimicrobial material at the surface of the porous article, wherein the microstructure at a surface of the porous article is only partially coated with the antimicrobial material.

Abstract: The invention relates to a method for placing a flexible jacket 3 on a natural vessel section 5, in particular a vein, to a device for placing a flexible jacket 3 in accordance with said method, and to an auxiliary instrument 1 for use in said method. The method comprises the following steps: pushing the jacket 3 onto a tubular application aid 2, filling the vessel section with a fluid, introducing, in particular pulling, the filled vessel section 5 into the application aid 2, the filling of the vessel section and the introduction of the vessel section 5 into the application aid 2 being carried out with the assistance of a tubular auxiliary instrument 1, and pulling the application aid 2 and the tubular auxiliary instrument 1 apart while at the same time pulling the vessel section 5 out of the application aid 2 and depositing the jacket 3 on the surface of the vessel section 5.

Abstract: The invention relates to an antimicrobial implant with a flexible porous structure composed of a biocompatible synthetic material which comprises particles of at least one antimicrobial agent.

Abstract: The object of the invention is a nonwoven vascular prosthesis (1) with pleats (3) in the vessel wall (2). In a process for producing the pleated, nonwoven vascular prosthesis, the vessel wall is formed on a rod-shaped core (6) having a corrugated surface (7) corresponding to the pleats.

Abstract: A flat implant for use in surgery is described. The implant includes a flexible fabric comprising two sides and having on one side a substantially closed surface and on the other side a three-dimensional microstructure permitting a growing in of cells. The implant can be more particularly used for the treatment of wall defects in body cavities, such as abdominal wall defects.
