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.
Claims16
An intervertebral device, comprising:
- a base having a bottom surface, a first end, a second end, and a longitudinal axis extending from the first end to the second end;
- a first body portion slidably coupled to the base and configured to move in a first direction with respect to the base, the first body portion including a bottom surface and a first engaging element;
- and
- a second body portion slidably coupled to the base and configured to move in a second direction with respect to the base, the second body portion including a top surface and a second engaging element,
- the first engaging element of the first body portion being configured to couple to the second engaging element of the second body portion, such that coupling of the first and second engaging elements prevents movement of the second body portion in a third direction with respect to the base when a compression force is present between the top surface of the second body portion and the bottom surface of the base, the third direction being substantially opposite to the second direction,
- the first and second body portions being configured such that movement of the first body portion in the first direction does not result in movement of the second body portion in the second direction,
- the first body portion configured to be positioned at one of a plurality of positions along the longitudinal axis of the base, the second body portion configured to be positioned at one of a plurality of positions at least perpendicular to the longitudinal axis of the base, each of the plurality of positions of the first body portion corresponding to a respective one of the plurality of positions of the second body portion.
