  • Patent number: 8328871
    Abstract: An expandable medical implant for supporting bone structures is disclosed. The implant may include an outer member and an inner member receivable in the outer member. One of the outer and inner members includes a tapered surface and the other of the outer and inner members includes a scalloped surface. The implant may also include a locking element disposed between the tapered surface and the scalloped surface. The tapered surface may be movable relative to the locking element to transversely shift the locking element into engagement with the scalloped surface to inhibit a decrease in the overall implant height.

  • Publication number: 20120048092
    Abstract: The present application is directed to devices and methods for cutting a spinal implant. In one embodiment, the device includes a handle and a head. The handle is sized to receive a predetermined length of the implant. A head is rotatably attached to the handle and includes a blade. After the implant is inserted into the handle, the head is rotated causing the blade to move around the implant and cut an excessive length from the predetermined length.

  • Patent number: 7998214
    Abstract: A vertebral implant comprises a tubular body sized to fit between two vertebral endplates and a pair of ring-shaped cleat assemblies. Each cleat assembly comprises an outer end wall, an inner end wall, and a side wall which defines a hollow bore. One or more spikes extend from each outer end wall, and each hollow bore is sized to fit over an end of the tubular body and slidably pass from the end along at least a portion of the length of the tubular body.

  • 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.

  • Patent number: 7674294
    Abstract: An end device attached to an implant and methods of use. The end device comprises a base having a receiving area, an opening, and at least one gate that is selectively positionable between open and closed orientations. The implant is sized to fit through the opening and into the receiving area when the gate is in the open orientation. Once inserted, the gate is sized to extend across at least a section of the opening and prevent the implant from escaping.

  • Patent number: 7621953
    Abstract: The present application is directed to spacing devices that attach directly or indirectly to vertebral implants. The spacing device may include a first side that faces the implant, and an angled second side that faces towards a vertebral member. The angled second side matches the shape of the vertebral member. The devices may further include apertures that receive spikes that extend outward from the implant. The second side may also include spikes that bite into and maintain the position of the device against the vertebral member. In one method of use, the spacing device may be rotated relative to the implant for the angled second side to match the vertebral member. The apertures are then placed over the spikes that extend outward from the implant to connect the spacing device to the implant.
