Spinous process fixation system and methods thereof

摘要

An implantable device may be provided. The implantable device may comprise an upper assembly comprising a ramped base and a pair of opposing windows. The pair of opposing windows may extend upward from either lateral side of the ramped base. A gripping assembly may be disposed in each window. The implantable device may further comprise a lower assembly comprising a ramped base and a pair of opposing windows. The pair of opposing windows may extend down from either lateral side of the ramped base. A gripping assembly is disposed in each window. The implantable device may further comprise a ramped actuator assembly disposed between the upper assembly and the lower assembly. The ramped actuator may be configured to transition the implantable device from a collapsed form having a first height to an expanded form having a second height and wherein the second height is greater than the first height.

1. An implantable device, comprising:
an upper assembly configured to grasp a spinous process comprising a base and a pair of opposing windows extending upward from either lateral side of the base, wherein a gripping assembly is disposed in each window; a lower assembly configured to grasp another spinous process comprising a base and a pair of opposing windows extending down from either lateral side of the base, wherein a gripping assembly is disposed in each window; and a ramped actuator assembly disposed between the upper assembly and the lower assembly and configured to transition the implantable device having a first height to an expanded a second height and wherein the second height is greater than the first height wherein the ramped actuator assembly comprises: a front ramped actuator in engagement with the upper assembly and the lower assembly; a rear ramped actuator in engagement with the upper assembly and the lower assembly; and a central screw that extends from the rear ramped actuator through the front ramped actuator wherein when the central screw is rotated in a first direction, the front ramped actuator and the rear ramped actuator are moved toward one another, causing the upper assembly and the lower assembly to move away from one another.
