This disclosure includes an expansion driver for adjusting expandable implants, the expansion driver including an input shaft operably connected to at least one bevel gear, the at least one bevel gear configured to engage each of a first gear and a second gear; the first gear connected to a first output shaft, the first output shaft terminating in a first driver configured to communicate with a first actuator of an expandable implant; the second gear connected to a second output shaft, the second output shaft annularly disposed around at least a portion of the first output shaft; and at least one pinion configured to transfer a torque from the second output shaft to a second driver extending parallel to the first driver and configured to communicate with a second actuator of the expandable implant. Upon a rotation of the input shaft, a torque is applied to at least one of the first driver and the second driver.

Expansion driver

A system for performing interbody fusion surgery including an expandable intervertebral spacer and specialized instruments for choosing the correct size of implant, implanting the device within the intervertebral space, and for delivery of bone graft or bone substitute to the interior of the implant.

Expandable spinal fusion implant, related instruments and methods

An expandable spinal fusion implant including first and second endplates coupled to an expansion member that sits within a housing. The expansion member is translated by a drive mechanism, whereby translation of the expansion member by the drive mechanism in a distal and proximal directions causes the distance between the endplates to increase and decrease, respectively.

Expandable fusion implant and related methods

An expandable spinal fusion implant including a housing, upper and lower endplates, a wedge positioned within the housing and between the upper and lower endplates and a drive mechanism to urge the wedge distally between the upper and lower endplates to increase the separation between the endplates and expand the overall height of the distal end of the implant.

Lordotic expandable interbody implant and method of using same

Lordotic expandable interbody implant

The present disclosure provides an expandable spinal implant comprising a plurality of moveable endplates pivotably connect to a housing.
