  • Patent number: 11369419
    Abstract: The present invention generally relates to bone implants. More specifically, the present invention relates to bone implants used for the fixation and or fusion of the sacroiliac joint and/or the spine. For example, a system for fusing and or stabilizing a plurality of bones is provided. The system includes an implant structure having a shank portion, a body portion and a head portion. The body portion is coupled to the shank portion and is configured to be placed through a first bone segment, across a bone joint or fracture and into a second bone segment. The body portion is configured to allow for bony on-growth, ingrowth and through-growth. The head portion is coupled to the proximal end of the shank portion and is configured to couple the shank portion to a stabilizing rod. Methods of use are also disclosed.

  • Patent number: 11234830
    Abstract: Bone implants, including methods of use and assembly. The bone implants, which are optionally composite implants, generally include a distal anchoring region and a growth region that is proximal to the distal anchoring region. The distal anchoring region can have one or more distal surface features that adapt the distal anchoring region for anchoring into iliac bone. The growth region can have one or more growth features that adapt the growth region to facilitate at least one of bony on-growth, in-growth, or through-growth. The implants may be positioned along a posterior sacral alar-iliac (“SAI”) trajectory. The implants may be coupled to one or more bone stabilizing constructs, such as rod elements thereof.

  • Patent number: 8465547
    Abstract: Methods and devices for spacing vertebral members using modular intervertebral devices and insertion tools. The devices may include opposing first and second endplates, and an intermediate member configured to fit between and support the endplates. The insertion tool may include an elongated handle and a distracter. A method of inserting the device using the tool may include inserting the endplates positioned on opposing sides of the handle into the intervertebral space and positioning the endplates in the intervertebral space relative to first and second vertebral members. The method may include deploying the distracter and increasing a distance between the endplates. Another step may include inserting the intermediate member into the intervertebral space and between the endplates and supporting the endplates with the intermediate member. The insertion tool may then be removed from the intervertebral space.

  • Patent number: 7901458
    Abstract: An implant for placing in the spine is disclosed. The implant has a tool engaging surface on its trailing end configured for intimate engagement with an insertion tool. The insertion tool configuration is particularly suited for implants made of brittle materials including bone and bone substitutes. Also disclosed is an insertion tool having a gripping end adapted for intimate engagement with an implant. In one embodiment, the insertion tool is operable by axial movement of one gripping arm with respect to the other.

  • Patent number: 7879096
    Abstract: An expandable medical implant for supporting skeletal structures. The medical implant having a length along its expandable dimension. The implant having a first tubular member with a connection end, an opposite skeletal interface end, and a central expansion instrument opening. Also, the implant has a second tubular member with a connection end configured to engage with the connection end of the first tubular member. The second tubular member having an opposite skeletal interface end. Additionally, an expansion instrument is insertable through the central expansion instrument opening and expandable against the first tubular member and the connection end of the second tubular member to expand the medical implant. The combined first and second tubular members are of a greater dimension along the length of the implant than the combined first and second tubular members are in any dimension perpendicular to their length.
