  • Patent number: 11752004
    Abstract: A system configured to increase height of a vertebral body. An implant includes plates each defining a bearing surface configured to be moved away from one another to expand the implant within the vertebral body. Supports are each coupled to one of the plates and include a reduced thickness portion defining a material web configured to plastically deform during expansion of the implant. The system includes an implant carrier with which an end element of the implant is removably coupled, and a rod configured to be translated relative to the implant carrier to cause expansion of the implant. An opposed portion may be coupled to the supports and configured to receive a longitudinal force to be moved relative to the end element. Second supports may be each coupled to the end element and one of the plates. Each of the second supports may plastically deform during expansion of the implant.

  • Patent number: 8236056
    Abstract: The invention provides an intervertebral implant for the lumbo-sacral joint, the implant consisting in a spacer suitable for being placed between the fifth lumbar vertebra and the sacral vertebra articulated thereto, the body of said spacer presenting in its top face a groove extending in the midplane of the spacer and suitable for receiving the spinous process of said lumbar vertebra. A longitudinal housing oriented orthogonally to said groove is formed in the bottom face and is suitable for receiving the top portion of the sacral vertebra. The longitudinal housing is defined by an extension and by a tab of width narrower than the width of the body of the spacer. The section of the housing in the midplane of the space is generally U-shaped, being inclined relative to the bottom of the groove.

  • Patent number: 7704281
    Abstract: An intervertebral implant for the lumbo-sacral joint is provided. The intervertebral implant comprises a spacer adapted to fit between the fifth lumbar vertebra and the sacral vertebra articulated thereto and a strap. The spacer comprises a body. The body comprises a top end face and a bottom end face opposite the top end face. The top end face comprises a groove that extends along a midplane of the spacer. The groove comprises a first side and a second side, wherein between the first side and the second side the groove is adapted to receive the spinous process of said lumbar vertebra. The bottom end face comprises a longitudinal housing. The longitudinal housing extends orthogonal to the groove. The longitudinal housing is adapted to receive and rest directly on a top portion of the sacral vertebra.

  • Patent number: 5757473
    Abstract: An optical strain sensor for measuring microdeformations of a surface with a resolution of at least 0.2 microns. The sensor comprises at least one camera for taking photographs of areas of the surface, the photographs being separated by a known fixed distance from one another before deformation has occurred. Templates are selected on the photographs taken before deformation, relocalized on photographs taken after deformation of the surface, and the deformation is derived from the computation of the difference in distances between the templates before and after deformation has occurred.
