  • Patent number: 5800544
    Abstract: The damaged portion of an injured tendon or ligament (C) ("connective cord") is inserted into a thin, hollow sleeve (100, 110, 120, 130, 140, 160, 180, 200, 240, 260, 270, 300, 390, generically designated "S") and is connected to the sleeve (S) such that the cord-sleeve combination can immediately withstand normal tensile forces. the interconnection can be mechanical, such as by pins (22, 22', 148, 150, 164, 188, 190, 206, 206', 210, 226, 230, 238, 239, 266, 286, 308) extending through the sleeve (S) and cord (C). The sleeve (S) can be bioabsorbable over a sufficiently long period of time that the cord (C) is healed by the time the sleeve (S) is absorbed.

  • Patent number: 5344602
    Abstract: A workpiece of a fiber-containing composite material is formed in a kinematically admissible manner by applying a tension loading to the workpiece in a transverse direction and passing the workpiece in the transverse direction through apparatus having a bending roller extending in the longitudinal direction over substantially the entire length of the workpiece. The workpiece is formed over the bending roller by introducing a net bending deformation into the workpiece and progressively propagating the bend transversely through the workpiece as the workpiece is moved in the transverse direction. The transverse laminar length of the workpiece remains substantially unchanged during the forming process. Preferably, the workpiece is contained within a vacuum bag during the forming operation.
