Barricaid is designed to close large defects in the anulus, so to prevent recurrent disc herniation, while allowing the surgeon to preserve more of the patient’s disc.
The Barricaid Annular Closure device consists of a woven polyester occlusion component intended to block an annular defect, while anchored to the adjacent vertebral body by a titanium bone anchor.
Measure size of annular defect following limited discectomy procedure. Patients with a large defect, i.e. 4-6mm in height and 6-12mm in width, are eligible for Barricaid.
Use of Alignment Trial to validate adequate access to the disc space and confirm correct angle for Barricaid implantation.
Position of Barricaid is confirmed under fluoroscopy.
