The Anova Containment Device, in conjunction with traditional rigid fixation, is intended for use in spinal fusion procedures as a means to maintain the relative position of weak bony tissue such as allografts or autografts. The device is not intended for load bearing indications.

The Anova Containment Device is a flexible, synthetic composite implantable mesh. It includes a polyester mesh component connected by a mono-filament suture to a porous expanded polytetrafluoroethylene or "ePTFE" component. This ePTFE component is placed between the polyester mesh and the overlying soft tissues. The ePTFE component is not anchored to the disc. The Anova Containment Device is attached to the spine with four suture anchors (two fastened to the vertebra above and two fastened to the vertebra below the disc). The sutures from the anchors overlay the mesh and hold it against the vertebral body and to reinforce the mesh against pressure from the graft material.
