The Devex Mesh System is also indicated for treating fractures of the thoracic and lumbar spine. The Devex Mesh System is designed to restore the biomechanical integrity of the anterior, middle, and posterior spinal column even in the absence of fusion for a prolonged period. The Devex Mesh System is intended for use with supplemental internal fixation. The supplemental internal fixation systems that may be used with the Surgical Titanium Mesh System include DePuy AcroMed titanium plate or rod systems (e.g. Kaneda SR, University Plate, M-2, ISOLA, VSP, Moss Miami, TiMX, Monarch and Profile). ## Device Story Devex Mesh System is a spinal intervertebral body fixation orthosis; used to replace diseased or fractured vertebral bodies in the thoracolumbar spine (T1-L5). Device provides structural support to restore vertebral height and biomechanical integrity of the spinal column. Intended for use in conjunction with supplemental internal fixation systems (e.g., titanium plates or rods). Operated by surgeons in a clinical/surgical setting. Benefits include spinal cord decompression and stabilization of the anterior, middle, and posterior spinal column. ## Clinical Evidence Bench testing only. Biomechanical testing, including static axial compression and dynamic axial compression, was conducted to evaluate performance. ## Technological Characteristics Material: Titanium alloy (Ti-6Al-4V). Form factor: Mesh-based vertebral body replacement cage. Energy source: None (mechanical implant). Connectivity: None. Sterilization: Not specified. ## 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 - Surgical Titanium Mesh System ([K003043](/device/K003043.md), [K020522](/device/K020522.md)) - Stackable Cage System ([K990148](/device/K990148.md), [K001340](/device/K001340.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
