In addition, when used as a pedicle screw fixation system, the KOBRA™GPS Fixation System is indicated for skeletally mature patients: (a) having severe spondylolisthesis (Grades 3 and 4) of the fifth lumbar-first sacral (L5-S1) vertebral joint; (b) who are receiving fusions using autogenous bone graft only; (3) who are having the device fixed or attached to the lumbar and sacral spine (L3 and below); and (4) who are having the device removed after the development of a solid fusion mass. ## Device Story The KOBRA™ GPS Fixation System is a spinal stabilization device consisting of cannulated rods and cannulated multi-axial screws. It is used by surgeons in the operating room to provide immobilization and stabilization of thoracic, lumbar, and sacral spinal segments as an adjunct to fusion. Components are implanted and locked into configurations tailored to the individual patient's anatomy. The system facilitates spinal fusion by maintaining alignment during the healing process. No software or electronic components are involved. ## Clinical Evidence No clinical data provided; substantial equivalence is supported by bench testing. ## Technological Characteristics System consists of cannulated rods and cannulated multi-axial screws for spinal fixation. Materials and design are consistent with previously cleared spinal fixation systems. Mechanical device; no energy source, software, or connectivity. ## Regulatory Identification A spinal intervertebral body fixation orthosis is a device intended to be implanted made of titanium. It consists of various vertebral plates that are punched into each of a series of vertebral bodies. An eye-type screw is inserted in a hole in the center of each of the plates. A braided cable is threaded through each eye-type screw. The cable is tightened with a tension device and it is fastened or crimped at each eye-type screw. The device is used to apply force to a series of vertebrae to correct “sway back,” scoliosis (lateral curvature of the spine), or other conditions. ## Predicate Devices - Vertelink KOBRA™ Fixation System ([K032102](/device/K032102.md)) - CD HORIZON® Spinal System ([K000453](/device/K000453.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Proposed Proprietary Trade Name: Vertelink KOBRA™ Fixation System - III. Classification Name: Spinal Intervertebral Fixation Orthosis and/or Pedicle Screw Spinal System (per 21 CFR Section 888.3060 and/or 888.3070) Class: Class II Product Code: MNH, MNI, KWO #### IV. Product Description The Medtronic Vertelink KOBRA™ GPS Fixation System consists of a variety of cannulated rods and cannulated multi-axial screws used to build a spinal construct. Instrumentation is also available to facilitate implantation of the device components. The KOBRA™ GPS Fixation System is intended to help provide immobilization and stabilization of spinal segments as an adjunct to fusion of the thoracic, lumbar, and/or sacral spine. The KOBRA™ GPS implant components can be rigidly locked into a variety of configurations, with each construct being tailor-made for the individual case. #### V. Indications When used as a pedicle screw fixation system of the non-cervical posterior spine in skeletally mature patients, the KOBRA™GPS Fixation System is indicated for one or more of the following: (1) degenerative spondylolisthesis with objective evidence of neurologic impairment, (2) fracture, (3) dislocation, (4) scoliosis, (5) kyphosis, (6) spinal tumor, and/or (7) failed previous fusion (pseudarthrosis). In addition, when used as a pedicle screw fixation system, the KOBRA™GPS Fixation System is indicated for skeletally mature patients: (a) having severe spondylolisthesis (Grades 3 and 4) of the fifth lumbar-first sacral (L5-S1) vertebral joint; (b) who are receiving fusions using autogenous bone graft only; (3) who are having the device fixed or attached to the lumbar and sacral spine (L3 and below); and (4) who are having the device removed after the development of a solid fusion mass. #### VI. Substantial Equivalence Documentation, including test reports, was provided which demonstrated the Vertelink KOBRA™ GPS Fixation System to be substantially equivalent to the Vertelink KOBRA™ Fixation System components previously cleared in K032102 and to the CD HORIZON® Spinal System (K000453).
