Abstract
Systems, devices, and methods for treating the spine are disclosed herein. Medical devices can be positioned along a subject's spine to treat various conditions and diseases. The medical device can include an actuator assembly and a clamp assembly. The actuator assembly can be positioned at an interspinous space between a superior spinous process and an inferior spinous process. The actuator assembly can be used to reconfigure the clamp assembly such that the clamp assembly clamps onto the superior and inferior spinous processes.

A method for delivering a spacer into a subject, the method comprising:
- positioning at least a portion of a spacer comprising an actuator assembly having a body with a longitudinal axis and a clamp assembly including a first wing and a second wing between a superior spinous process and an inferior spinous process of the subject such that the superior spinous process and the inferior spinous process are received by the clamp assembly;
- rotating the first wing and the second wing relative to the body and away from an anterior-posterior orientation towards an inferior-superior orientation;
- and
- rotating a portion of the actuator assembly about the longitudinal axis of the body to move the clamp assembly from an open configuration to a clamping configuration such that the first wing and the second wing move towards one another and towards the body of the actuator assembly in a direction transverse to the longitudinal axis of the body.
A method for delivering a spacer into a subject, the method comprising:
- positioning at least a portion of a spacer comprising an actuator assembly having a body with a longitudinal axis and a clamp assembly including a first wing and a second wing between a superior spinous process and an inferior spinous process of the subject such that the superior spinous process and the inferior spinous process are received by the clamp assembly;
- rotating a portion of the actuator assembly about the longitudinal axis of the body to allow the first wing of the clamp assembly to rotate relative to the body about a first axis of rotation positioned on a first side of a sagittal plane of the subject and the second wing of the clamp assembly to rotate relative to the body about a second axis of rotation positioned on a second side of the sagittal plane opposite the first side and causing the clamping assembly to move from an open configuration to a clamping configuration such that the first wing and the second wing move towards one another and towards the body of the actuator assembly in a direction transverse to the longitudinal axis of the body.
A method for delivering a spacer into a subject, the method comprising:
- positioning at least a portion of a spacer comprising an actuator assembly having a body with a longitudinal axis and a clamp assembly having a first wing and a second wing between a superior spinous process and an inferior spinous process of the subject;
- rotating the first wing and the second wing relative to the body;
- and
- rotating a portion of the actuator assembly about a longitudinal axis of the body with a delivery instrument to move the clamp assembly from an open configuration to a clamping configuration such that the first wing and the second wing move towards the body of the actuator assembly in a direction transverse to the longitudinal axis and engage with the superior and inferior spinous processes.
