Barricaid® prosthesis for partial annulus replacement

Specialties: Neurology & neurosurgery

Technology Type: Devices - Procedures

Stage of development: Nearly established

Stage of EAA: Revised assessment

Description, patients and keywords:

The Barricaid® prosthesis (Intrinsic Therapeutics, Massachusetts, United States of America) is a small piece of flexible polymer mesh composed of multiple layers of non-degrading polyethylene terephthalate fibres. The mesh, which contains platinum-iridium markers that make it visible on x-ray images, comes in various sizes (8, 10 and 12 mm) and is preloaded in a single-use delivery system. Towards the end of a spinal discectomy procedure, once the herniated disc material is removed, the Barricaid® mesh is placed on the inner surface of the disc annulus using fluoroscopic guidance and secured to the surrounding vertebral bone with an embedded titanium anchor. The mesh expands across the posterior intervertebral space to close the opening created during discectomy. Placement of the mesh takes an additional 5 to 15 minutes just prior to wound closure in a surgery that takes approximately 2 hours
