Abstract: The invention concerns polyurethane (PUR) having an antithrombogenic coating, wherein the antithrombogenic coating comprises at least one antithrombogenic substance covalently bound to a surface of the PUR via at least two bonds, wherein a first of said bonds is an amide bond between the surface of the PUR and a polyethyleneimine (PEI) and a second of said bonds is between the PEI and the antithrombogenic substance, wherein the surface of the PUR had been activated by use of a carbon dioxide plasma or a plasma modified by addition of carbon dioxide before the first of said bonds was formed.

Abstract: A hernia mesh fabric for repair of in particular inguinal or hiatus hernias comprises a base sheet (1) of layered, flexible mesh material; a passage (3) in the base sheet (1) for a body canal, in particular for the spermatic cord or the oesophagus; an insertion slit (5) between the contour (4, 9) of the base sheet (1) and the passage (3) for insertion of the body canal into the passage (3); and a sewing bridge (7) which is located in the vicinity of the mouth (6) and able to be folded down on the insertion slit (5) and, on both sides thereof, to be stitched to the mesh material of the base sheet (1).

Abstract: An implantable prosthesis for repairing hernia defects comprises a basic structure (6) which is provided with concertina pleats (3) that are parallel to a direction of extension. They are fixed by a fixing arrangement so that the basic structure (6) is approximately hourglass-shaped in a plan view.

Abstract: A soft tissue implant such as a breast implant, calf muscle prosthesis and the like, comprises an external shell-type envelope (1) of flexible plastic material, in particular of silicone; a liquid to viscous filler material (5) contained in the envelope (1); and a metal-containing, biocompatible, continuous coating (9) on the outside (7) of the envelope (1).

Abstract: An absorbable implant comprises a basic compound made of a material which can be absorbed by the body of the implant recipient. A coating which contains titanium partially covers the basic compound, so that the latter comprises coating-free zones for the body to engage and absorb.

Abstract: A surgical flat implant for preventing tissue-to-tissue adhesion in operated areas, in particular for post-operative repair in pericardial, peritoneal and gynaecological surgery, comprises at least one layer (1) of a thin, bioresorbable, smooth film and a stabilizing layer in form of a reinforcing mesh (2) of plastic material which is provided with a metal-containing, biocompatible, continuous coating (4).
