Abstract: An expandable intervertebral cage includes vertically opposed superior and inferior plates and longitudinally opposed distal and proximal wedges disposed between the plates. The wedges define ramps that engage complimentary ramps of the superior and inferior plates to increase a vertical distance between the plates. An actuator is located between the plates, defines a central, longitudinal axis, and is coupled to the wedges such that, as the actuator rotates about the axis, at least one of the wedges moves longitudinally relative to the other, thereby increasing the vertical separation distance. At least one locking component is insertable within a receptacle at least partially defined by the proximal wedge and is configured to transition from an unlocked configuration, where the actuator is rotatable relative to the proximal wedge, to a locked configuration, where the actuator is rotationally affixed relative to the proximal wedge.

Abstract: Anchoring devices for rachidian implants, implants, surgical instruments, and surgical systems and methods are disclosed. In some embodiments, an anchor comprises a stiff plate with a longitudinal axis, configured for penetration of its anterior end into a vertebral surface while its posterior end remains engaged with the implant. An implant may include a locking mechanism for the anchor. An anchor may include an abutment configured to abut a complementary abutment of an implant. In some configurations, inserting an anchor in a passage of an implant may displace a locking mechanism, which may resile and lock the anchor in the implant with complementary abutments of the anchor and implant abutting.

Abstract: An implant for therapeutically separating bones of a joint has two endplates each having an opening through the endplate, and at least one ramped surface on a side opposite a bone engaging side. A frame is slideably connected to the endplates to enable the endplates to move relative to each other at an angle with respect to the longitudinal axis of the implant, in sliding connection with the frame. An actuator screw is rotatably connected to the frame. A carriage forms an open area aligned with the openings in the endplates. The openings in the endplates pass through the carriage to form an unimpeded passage from bone to bone of the joint. The carriage has ramps which mate with the ramped surfaces of the endplates, wherein when the carriage is moved by rotation of the actuator screw, the endplates move closer or farther apart.

Abstract: An expandable interbody fusion implant device has a frame, two ramp assemblies and two overlying base plates driven by two independent drive shafts. The two ramp assemblies include a distal ramp assembly and a proximal ramp assembly. Each ramp assembly has a translating ramp, a first pivoting hinged ramp and a second pivoting hinged ramp. The two overlying base plates include a first base plate overlying a second base plate. Each base plate is hinged to the distal ramp assembly and the proximal ramp assembly at an end of one of said pivoting hinged ramps of each ramp assembly. The two independently driven drive shafts include a first drive shaft for translating the distal ramp assembly and a second drive shaft for translating the proximal ramp assembly to independently expand the implant proximally or distally or both.

Abstract: A spinal implant which is configured to be deployed between adjacent vertebral bodies. The implant has at least one extendable support element with a retracted configuration to facilitate deployment of the implant and an extended configuration so as to expand the implant and effectively distract the disc space, stabilize the motion segments and eliminate pathologic spine motion. The implant has a minimal dimension in its unexpanded state that is smaller than the dimensions of the neuroforamen through which it typically passes to be deployed within the intervertebral space. The implant is provided with a locking system having a plurality of linked locking elements that work in unison to lock the implant in an extended configuration. Bone engaging anchors also may be provided to ensure secure positioning.
