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 tubular vessel prosthesis includes an inner surface and an outer surface and a wall, where the vessel prosthesis has a coloration on the inner and/or outer surface which brings about a contrast between the inner surface and outer surface.

Abstract: A woven aortic sinus prosthesis has a first substantially cylindrical section position away from a patient's heart, which optionally passes into an aortic arch of the patient, a second section having a greater diameter than the first section and forming a bulb, which second section is connected to the first section, and optionally a third substantially cylindrical section close to the heart, which is connected to the bulb section, wherein the prosthesis is continuously woven and has a constant number of warp yarns over its axial length, whereby there is a greater distance between the warp yarns in a region of the bulb section than in the first and third cylindrical sections.

Abstract: A woven textile vascular prosthesis including a tubular trunk and at least one fork, each fork having an apex located between outgoing tubular branches with a small diameter, wherein at least a portion of a wall of the prosthesis in a zone of the apex is woven more densely than in other zones having an original weave construction.

Abstract: A surgical implant is made from biocompatible fiber material as a woven textile fabric, in particular in the form of a vascular prosthesis, the woven fabric being so configured that its permeability to blood is so low that the blood impregnates the textile fabric upon implantation and seals it off by coagulating, but does not flow through it.

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: A medical device comprising a porous article of expanded polytetrafluoroethylene (ePTFE) having a microstructure comprising nodes interconnected by fibrils, wherein the microstructure at a surface of the article at least partially includes nodes having segments free of fibrillate interconnections.

Abstract: A sheathing has a longitudinal direction and a transverse direction for restoring function of venous valves of varicose veins in the form of a planar, flexible piece of material, wherein the piece of material includes a nonwoven material.

Abstract: High-purity, acetone-soluble, absorbable components of medical devices are designed for optimum interfacing with human blood or the cell lining of a body cavity, and are formed of a crystalline, segmented l-lactide polyaxial copolymer structurally tailored to have certain molecular dimensions, thermal and physicomechanical properties, and solubility characteristics to allow their uses, optimally, as parts of vascular, urological, and post-surgical adhesion prevention devices.

Abstract: A tubular implant that replaces natural blood vessels includes a prefabricated vascular prosthesis with an internal surface, an external surface and a wall, wherein the internal and/or external surface of the prefabricated vascular prosthesis has a polyurethane coating.

Abstract: The invention relates to a textile vascular prosthesis (1) with a circulatory pleating formed by folds (4), and with an arch-shaped longitudinal flexion (2) extending over at least a partial section and formed by asymmetric shortening gathering of the prosthesis wall by means of at least one longitudinal seam (7) extending along the partial section. The at least one longitudinal seam gathers the prosthesis wall while preserving the accordion-like structure (4) and the compacted state of the pleating (4) in the longitudinal direction.

Abstract: Textile vascular prostheses having a coating include an absorbable polymer in the form of a three-armed polyester having terminal hydroxyl groups from hydroxy acids polymerized onto a central trifunctional hydroxy compound, the three arms being tetrapolymers of lactide, ?-caprolactone, trimethylene carbonate and glycolide. The polymer is composed of about 30 to about 45 mol % of lactide, about 20 to about 40 mol % of ?-caprolactone, about 10 to about 28 mol % of trimethylene carbonate and about 10 to about 25 mol % of glycolide.

Abstract: Sheathing for reinforcing natural veins for use as surgical implants in the form of textile netting that is configured by forming a seamless, tubular, essentially pile-less, knit fabric and has loops having large, open apertures having essentially polygonal shapes is made available.

Abstract: A tubular vessel prosthesis includes an inner surface and an outer surface and a wall, where the vessel prosthesis has a coloration on the inner and/or outer surface which brings about a contrast between the inner surface and outer surface.

Abstract: Sinus patches for replacing defective sinuses at the aortic sinus include a flat, flexible, domed piece of wall material which, except for possibly having pleats, has a three-dimensional dome shape, which is determined by the wall material itself.
