Abstract: A bone implant system may include a plurality of bone anchors, a superior rod attachable to a superior portion of a bone via the bone anchors, and an inferior rod attachable to an inferior portion of the bone via the bone anchors. The superior rod may have a superior end, and the inferior rod may have an inferior end. The superior rod may telescopically engage the inferior rod such that a cavity is present within at least one of the superior rod and the inferior rod and such that a length of the combined superior and inferior rods, measured between the superior end and the inferior end, is adjustable. The cavity may contain a micropump and a chamber. The micropump may be configured to expel fluid into the chamber to urge the length to increase.

Abstract: Growing rod systems and methods for correcting spinal deformities include at least one growing rod assembly and at least one fluid delivery assembly. Each growing rod assembly includes a fluid actuator that is operable to extend first and second rod segments in opposite directions along the spine. The fluid actuator can be provided by, for example, a piston-cylinder actuator. Each fluid delivery assembly includes a fluid pump operably connectable to a fluid line, which in turn is connected to the fluid actuator. In one embodiment, the fluid actuator is of a linear design. In another embodiment, two linear or curvilinear fluid actuators are provided back-to-back and connected by a connecting rod that mounts to the mid-spine and is contourable. In another embodiment, the fluid actuator is of a curvilinear design to generally conform the normal spine. And in another embodiment, the fluid actuator includes a fluid-over-fluid shock absorber.
