  • Patent number: 11957602
    Abstract: 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.

  • Patent number: 11918489
    Abstract: 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.
