Barricaid

Barricaid - Prevent Reherniation. Preserve discs.

Barricaid is an anular closure device by Intrinsic Therapeutics, which can be implanted following a limited microdiscectomy. Using Barricaid reduces the risk of reherniations and preserves the function of the disc.

What is the clinical problem?

In the past, the standard treatment for disc herniation is discectomy. Even if this technique is established as a successful technique, there exists a high risk of reherniation, because the anulus is not completely closed. In patients with anulus defects ≥ 6mm, reherniation occurred in 27% of the treated patients.

To treat patients with large anulus defects and to reduce the risk of reherniation, surgeons started to aggressively remove the remaining parts of the nucleus pulposus. With this approach, revision rates can be reduced, but the clinical outcome and patient satisfaction significantly decreased.

Barricaid is an anulus closure device, that preserves the disc by closing the anulus defect properly and reducing reherniation.

How does Barricaid work?

The Barricaid implant consist of two main parts: A polyester occlusion component that maintains nucleus inside the disc by replacing the defective region of the nucleus, and a titanium anchor, that fixates the implant in the vertebrae, resisting migration of the implant.

Barricaid is implanted in a preloaded condition. If the implant is inserted into the bone, the preloading gets reduced, and the polymeric mesh will be pressed due to the pressure in the disc against its wall, closing the defect. 

 

What are the advantages of Barricaid?

Implanting Barricaid enables a limited microdiscectomy. The native nucleus can be preserved to stabilize the disc. Barricaid restores the original disc height and significantly reduces the risk for a second disc prolapse.

Expected Results

Barricaid has been implanted since 2008. Previous studies showed, that Barricaid is able to significantly reduce the reherniation rate in high-risk patients. Patient satisfaction can be significantly increased.
