Abstract

An expandable intervertebral implant having an upper body portion, a lower body portion opposite the upper body portion, a wedge member connecting the upper body portion to the lower body portion, a nose member having a tapered distal end and a proximal end opposite the distal end, and an actuator disposed between the nose member and the wedge member, for translation of the wedge member along a longitudinal axis of the implant. A pin disposed in a center of the nose member connects to the actuator for centering the nose member with the actuator. Translation of the wedge member along the longitudinal axis of the implant displaces the upper body portion and the lower body portion away from each other, thereby expanding the intervertebral implant.

Dependent claims

An expandable intervertebral implant comprising:

an upper body portion;
a lower body portion opposite the upper body portion;
a wedge member connecting the upper body portion to the lower body portion;
a nose member having a tapered distal end and a proximal end opposite the distal end, the nose member slidably connected to the upper body portion and the lower body portion;
an actuator having a connection for fitting a driver which engages the actuator where the connection is interior to the wedge member and disposed closer to the nose member than a posterior of the implant, for translation of the wedge member along a longitudinal axis of the implant;
and
the actuator on a first side slidably connected the nose member and on a second side connected to the wedge member
wherein
translation of the wedge member along the longitudinal axis of the implant displaces the upper body portion and the lower body portion away from each other, thereby expanding the intervertebral implant.
