Abstract:
Methods and apparatus for providing correction of one or more maladies or conditions of the spinal column of a living being. In one embodiment, the apparatus includes an implantable device configured to be selectively adjustable in one or more portions thereof so as to permit correction of asymmetries or irregularities of the spinal column via insertion into one or more affected intervertebral disc spaces. In one variant, the implantable device includes upper and lower host elements which are hinged or can pivot relative to one another, and an insertable distraction mechanism which is adjustable to enable one side or the other of the implantable device to alter height. In another variant, both sides of the implantable device can be adjusted for height via the host elements and one or more pivots or hinges. In one implementation, the distraction mechanism is adjustable from multiple approaches into the disc space.
Abstract:
Apparatus and methods for spinal the treatment of abnormal spinal stability and stenosis of the spinal canal. In one embodiment, the apparatus and methods provide treatment via decompression and/or fixation of the spinal canal. One or more implants are used to fixate the posterior column of a spinal segment compromised of the superior and inferior immediately adjacent vertebral bones. In one variant, these disclosed devices are used to fixate the posterior column of a spinal segment while another orthopedic implant is placed into the anterior column of the same spinal segment, thereby providing circumferential decompression.
Abstract:
Orthopedic implant and methods of implantation for fixing adjacent bones. In one embodiment, the implant includes a locking mechanism that is adapted to be advanced by a locking instrument, wherein advancement of the locking mechanism in a first direction produces rotation of a first rigid abutment surface of the implant from a first orientation to a second orientation, and continued advancement of the locking mechanism produces advancement of the first rigid abutment surface towards a second rigid abutment surface of the implant. The continued advancement may also place a compressive load onto the implant sufficient to immobilize the implant relative to a first bony surface and a second bony surface.

Abstract:
Disclosed is a bone fusion cage that contains bone graft and is implanted between bones in a skeletal system. The cage bears structural loads that are transmitted through the bones of the skeletal system and at least partially shields the contained bone graft from the structural loads. The cage is configured to provide a secondary load to the bone graft independent of the structural load to promote fusion of the bone graft to adjacent bones.
Abstract:
Described herein are devices and methods for fusion of adjacent vertebral bones using distractor platforms for exposure and resection of at least a portion of the facet joint, such as in performance of a TLiF procedure. In one embodiment, the distractor platform contains at least a first receptacle and/or extension adapted to couple to the implanted screw/bone marker and the method includes advancing a threaded segment of a bone fastener assembly into the identified first pedicle of the first vertebral bone, the first bone fastener assembly further comprises a second segment adapted to couple with a distraction platform adapted to concurrently attach onto at least one tissue retention blade and adapted to retain the tissue retention blade in the displaced position. Stabilization of a spinal segment is also provided by advancing a substantially concave orthopedic implant through an opening made in a posterior aspect of a disc space.
Abstract:
Disclosed herein are devices and systems adapted to position within a subject and methods of use therewith. The device includes a conduit body having at least a first layer and a second opposable layer manufactured from a biocompatible and malleable material that permits safe positioning within the subject. The device also includes an enclosed intervening cavity positioned between the first and second layers, the first surface of the first layer having at least one feature configured to interlock with the second surface of the second layer. The conduit body is configured to transition from a first state to a second state upon application of a suction force to the intervening cavity wherein the conduit body is less rigid in the first state than when the conduit body is in the second state, and wherein the conduit body is adapted to remain in the second state after removal of the suction force.
Abstract:
An orthopedic device is adapted to fixate the spinous processes of vertebral bones. The device includes at least one bone engagement member. When implanted, a bone engagement member is located on each side of a spinous process and adapted to forcibly abut the side of each spinous process.
