Embodiments of the invention include expandable, implantable devices and methods. Devices expand linearly to provide secure fixation between or among anatomical structures. In some embodiments, an implant replaces one or more vertebral bodies of the spine.

Expandable implant, instrument, and method

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.

Centrally driven expandable implant

Intervertebral spacers are provided for use in orthopedic treatment of spinals defects. The intervertebral spacer is formed of a shape memory polymer. The spacer can be fabricated into a desired configuration and then deformed into an alternative or deformed configuration. Cooling the deformed spacer effectively freezes the spacer into its deformed conformation. The deformed configuration can be selected to facilitate implantation of the spacer into a prepared disc space between adjacent vertebrae. During operation, the surgeon can heat the spacer to allow it to revert to its original configuration. The spacer in its original conformation is sized to restore and/or maintain the adjacent vertebrae in a desired conformation and disc space height.

Laterally expanding intervertebral fusion device

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.

End device for a vertebral implant

Embodiments of the invention include expandable, implantable devices and methods with a locking feature. Devices expand linearly to provide secure fixation between or among anatomical structures. In some embodiments, an implant replaces one or more vertebral bodies of the spine.

Locking expandable implant and method

This invention relates to intervertebral spacers for use in orthopedic treatment of spinal defects. The intervertebral space is formed of a shaped memory polymer material. The spacer can be fabricated into a desired configuration and then deformed into an alternative or deformed configuration. Cooling the deformed spacer effectively freezes the spacer into its deformed conformation. The deformed configuration can be selected to facilitate implantation of the spacer into a prepared disc space between adjacent vertebrae. During operation, the surgeon can heat the spacer to allow it to revert to its original configuration. The spacer in its original conformation is sized to restore and/or maintain the adjacent vertebrae in a desired conformation and disc space height.

Vertically expanding intervertebral body fusion device

This invention relates to intervertebral spacers for use in orthopedic treatment of spinal defects. The intervertebral space is formed of a shape memory polymer. The spacer can be fabricated into a desired configuration and then deformed into an alternative or deformed configuration. Cooling the deformed spacer effectively freezes the spacer into its deformed conformation. The deformed configuration can be selected to facilitate implantation of the spacer into a prepared disc space between adjacent vertebrae. During operation, the surgeon can heat the spacer to allow it to revert to its original configuration. The spacer in its original conformation is sized to restore and/or maintain the adjacent vertebrae in a desired conformation and disc space height.
