Abstract: A device, whose purpose is such internal shielding of a vascular anastomosis that undesirable perivascular vibration is avoided, is created from a stiff or possibly moderately elastic, non-resorbable, biologically inert, non-moistenable and sterilizable material. The shield has the form of an incomplete tube (4), whose length is at least five times larger than the diameter of the targeted vessel or substitute. This incomplete tube (4) in the third and fourth fifths of its length (counting counter to the course of blood flow) is provided with an orifice (5) having a width of at least one quarter of the circumference of the tube. From the apical end of the orifice (5) and/or from the rear end of the said orifice (5) projects a gradually tapered tongue-shaped structure (6, 10) which is moderately bow-curved externally. The margin (8) of the orifice (5) and all margins of the device are blunt, and the whole internal surface of the device is highly polished.

Abstract: A device for non-surgical sealing of the interstice in the wall of a vessel is provided. The device includes a tubular, resorbable collagen plug 4 having longitudinal cut 8 in the form of a V. The device can further include applicator 5. The opening of cut 8 of plug 4 is located on the peripheral portion of plug 4. The internal diameter of plug 4 corresponds to the external diameter of catheter 3 which is introduced into vessel 1. The external diameter of plug 4 corresponds to the external diameter of applicator 5. Plug 4 includes inner and outer layers of resorbable collagen which have differing swelling rates. Applicator 5 includes longitudinal cut 10 in the form of a V. The opening of cut 10 is located on the peripheral side of applicator 5 relative to vessel 1.

Abstract: The invention relates to three-layer vascular prostheses comprising an internal layer 1, a middle layer 2 and an external layer 3 which is characterized in that the middle layer 2 is made from a physiologically non-resorbable, porous material, and the internal layer 1 and the external layer 3 are self-supporting and are made from a physiologically resorbable, fibrillar material, and are tanned. The internal layer 1 and the external layer 3 preferably consist of collagen, but have different resorbability. The middle layer 2 is preferably made from inert fibers, preferably synthetic fibers, by means of textile technology. The biologically resorbable layers preferably comprise chemically or physically bonded or incorporated pharmacologically active substances.

Abstract: A device for osteosynthesis of bones by intra-marrowial fixation includes a tube (2) made of a non-elastic material, adapted to be inserted into the marrow cavity of a bone (1), one end (2') being sealed, and the other end being open, and a connection part (13), comprising a fixation part (4) designed to be inserted into the tube (2) for the fixation of the tube (2) in a hole of the bone (1), and a vent part (12) designed to be inserted into the fixation part (4) and for a tight connection therewith, and including a connection (8) for a line (14) for introducing a pressurized biologically inert liquid (10) into the tube (2) and releasing it therefrom, and a valve (9) for opening and closing the liquid passage through the vent. The tube (2) is filled with a biologically unobjectionable sterilizable liquid (10), for example water, gelatin solution or dextran solution, under a pressure of 200 to 1000 kPa.
