  • Publication number: 20180008253
    Abstract: An access device for accessing an intervertebral disc having an outer shield comprising an access shield with a larger diameter (˜16-30 mm) that reaches from the skin down to the facet line, with an inner shield having a second smaller diameter (˜5-12 mm) extending past the access shield and reaches down to the disc level. This combines the benefits of the direct visual microsurgical/mini open approaches and the percutaneous, “ultra-MIS” techniques.

  • Publication number: 20150045890
    Abstract: An intervertebral disc prosthesis comprises a structure having a rigid upper plate, a rigid lower plate, and a core inserted between said plates, the structure being made from thermoplastic material, the core further comprising a thermoplastic monomaterial having graduated elastic and damping properties. According to one alternative, the core is composed of an elastomeric central nucleus surrounded by one or more rings which are referred to as rings having ranks j relative to the core, and which are more rigid.

  • Patent number: 8337560
    Abstract: An intervertebral disk prosthesis, having a rigid top plate, a rigid bottom plate, and an elastically deformable intermediate cushion housed between the two inner surfaces of the plates. The cushion, at rest, possesses a wedge-shape possessing at least one front notch open into the larger end of the wedge and one rear notch open into the narrower end. The faces of the notches co-operate by contact over an area of magnitude that varies as a function of the intensity and/or direction of the load to which the prosthesis is subjected. The bottoms of the notches are spaced apart from each other and situated in the narrower half of the prosthesis.

  • Publication number: 20110270311
    Abstract: Implant for the cervical spine comprising an anterior plate (1) for maintaining a bone graft, bone anchorage screws (6,7,8) for the plate and means (22) for blocking the screws and preventing any migration of the screws, characterized in that the blocking means comprises at least one slide (22) slidably mounted on the plate so as to be applicable on at least one anchorage screw head (15, 16). The slide cooperates with means (33, 34) for retaining the slide on the head of the screw. The slide may be formed by a thin platelet (22a) which is provided with lateral flanges (25) and is slidable in a complementary cavity (18) provided in the plate (1) while being flush with the surface of the plate (1). The plate (1) includes ramps (26) for retaining the slide (22) on which the flanges (25) are slidable, the slide (22) being slidable to a position in which it at least partly overlaps the heads of the associated screws (6 or 7) and is locked in position by suitable means.

  • Patent number: 7819920
    Abstract: A vertebral replacement implant includes two longitudinal elements slidably mounted with respect to each other, and locking elements. These locking elements include, on one of the longitudinal elements, an anchor surface, and on the other of the longitudinal elements, an anchor shoe guided in translation to take up a first position in which the elements slide freely with respect to each other, and a second position in which the anchor shoe cooperates with the anchor surface to lock the elements together, with a system converting a rotational movement into a translational movement transmitted to the anchor shoe.
