Abstract

Embodiments of the present disclosure relate to devices and methods for treating one or more damaged, diseased, or traumatized portions of the spine, including intervertebral discs, to reduce or eliminate associated back pain. In one or more embodiments, the present disclosure relates to an expandable interbody spacer. The expandable interbody spacer may comprise a first jointed arm comprising a plurality of links pivotally coupled end to end. The expandable interbody spacer further may comprise a second jointed arm comprising a plurality of links pivotally coupled end to end. The first jointed arm and the second jointed arm may be interconnected at a proximal end of the expandable interbody spacer. The first jointed arm and the second jointed arm may be interconnected at a distal end of the expandable interbody spacer.

Claims20

Dependent claims

A system for treating a vertebral condition, the system comprising:

an interbody implant configured to transition between a first configuration and a second configuration, wherein the interbody implant comprises:
a first arm including a first end and a second end, wherein the first arm is defined by a plurality of links coupled to one another;
a second arm including a first end and a second end, wherein the second arm is defined by a plurality of links coupled to one another;
a proximal component coupled to the first ends of the first and second arms;
and
a distal component coupled to the second ends of the first and second arms;
an insertion tool for positioning the implant within a patient, the insertion tool comprising:
an elongate member defining a distal end and a lumen extending therethrough, wherein the elongate member is configured to releaseably engage the proximal component of the interbody implant;
and
a shaft member disposed within the lumen of the elongate member and configured to releasably engage the distal component, wherein actuation of the insertion tool moves the elongate member relative to shaft member to transition the implant between first configuration and the second configuration
