  • Patent number: 8152857
    Abstract: A tension-free elastic tape is used for the surgical treatment of female urinary incontinence. The tape has a textile structure that allows ingrowth of the tape into the connective tissue. On its longitudinal edges, the tape has edge threads (2, 4, 6, 8) that project from the textile structure of the tape and that especially facilitate a good primary anchoring of the tape in the tissue. The edge threads are firmly incorporated in the structure of the tape.

  • Patent number: 7198799
    Abstract: A biologically resorbable nerve guide rail with a microporous guide tube of polymers of hydroxycarboxylic acids, where the porosity allows a metabolism through the tube wall, but prevents the passage of cells, and optionally several monofilaments of polymers of hydroxycarboxylic acids located in the guide tube, is characterized in that the inner surface of the tube and/or the surface of the monofilaments have an orientation aid for longitudinally oriented colonization with Schwann's cells.

  • Patent number: 6736731
    Abstract: A cross member unit for universal joints has a cross member (6) with four trunnions (17). Each two trunnions define a common longitudinal axis (7). Each trunnion (17) has an end face (18), a first sealing face (21) and a pre-sealing face (24). The pre-sealing face (24) is remote from the end face 18 and has a diameter increasing relative to the first sealing face (18). A bearing bush (9) is on each trunnion (17). Each bearing bush (9) has an open end 29 and has rolling contact members 27 rotatably supporting the trunnion (17) around the longitudinal axis (7) of the trunnion (17). An annular seal (30) is provided in each bearing bush 9. The annular seal (30) is held in the bearing bush 9 by a press fit. The annular seal (30) includes an annular carrier (31) which projects from the open end (29) of the bearing bush (9). The annular seal includes at least one first sealing lip (35) which is in contact with the first sealing face (18) of the trunnion (17).

  • Patent number: 5104398
    Abstract: A surgical suturing thread is coated with a fatty acid metal salt. For this purpose it is dissolved in an organic solvent and the suturing thread is coated with the hot solution, whose temperature is so high that the fatty acid metal salt remains in the dissolved state. The solvent is then evaporated from the thus applied coating at elevated temperature.
