Abstract
Intervertebral devices and systems, and methods of their use, are disclosed having configurations suitable for placement between two adjacent vertebrae, replacing the functionality of the disc therebetween. Intervertebral devices and systems contemplated herein are implantable devices intended for replacement of a vertebral disc, which may have deteriorated due to disease for example. The intervertebral devices and systems are configured to allow for ample placement of therapeutic agents therein, including bone growth enhancement material, which may lead to better fusion between adjacent vertebral bones. The intervertebral devices and systems are configured for use in minimally invasive procedures, if desired.
Claims21
-24. (canceled)
An intervertebral device, comprising:
- a base including a bottom surface, a first end and a second end;
- a first body portion slidably attached to the base and configured to move at least parallel to a longitudinal axis of the base, the first body portion including a first plurality of engaging elements,
- a second body portion including a top surface, the second body portion slidably attached to the base and configured to move at least perpendicular to the longitudinal axis of the base,
- the base including a second plurality of engaging elements, the first and second pluralities of engaging elements being configured to prevent movement of the second body portion when a compression force is present between the top surface of the second body portion and the bottom surface of the base.
An intervertebral device system, comprising:
- an intervertebral device, including:
- a base including a bottom surface, a first end and a second end;
- a first body portion slidably attached to the base and configured to move at least parallel to a longitudinal axis of the base, the first body portion including a first plurality of engaging elements;
- and
- a second body portion including a top surface, the second body portion slidably attached to the base and configured to move at least perpendicular to the longitudinal axis of the base, the base including a second plurality of engaging elements, the first and second pluralities of engaging elements being configured to prevent movement of the second body portion when a compression force is present between the top surface of the second body portion and the bottom surface of the base;
- and
- a delivery device, including:
- an expansion tool, the expansion tool having a handle and an elongate shaft coupled to the handle;
- and
- an attachment assembly, the attachment assembly having a first end and a second end, the first end of the attachment assembly being configured to couple to one of the first or second ends of the base and the second end of the attachment assembly being configured to couple with the handle of the expansion tool,
- the elongate shaft of the expansion tool having a proximal end and a distal end, the distal end of the elongate shaft configured to couple with the first body portion, the proximal end of the elongate shaft configured to couple with the handle of the expansion tool, such that movement of the elongate shaft results in movement of the first body portion with respect to the base of the intervertebral device.
