Benefits of technology

[0021] The present invention improves upon current techniques by creating a biological disc replacement that induces living, natural fibrous tissue growth into the DDD cavity. It is believed that living, natural fibrous tissue is preferable to dead and/or dying DDD tissue. First, living natural fibrous tissue does not exhibit acidic properties nor leak chemicals that may cause nerve inflammation and back pain. Second, living natural fibrous tissue offers more support and

Embodiment Construction

[0034] The present invention mimics the biomechanics of a natural disc nucleus by inducing natural fibrous tissue growth. FIG. 1 depicts the device 10 of the present invention embodied in a preparation of multilayered bands of suitable fibrous tissue promoting material piled in a circular configuration 12 formed to fit securely in the DDD cavity 14. The suitable fibrous tissue promoting material may include, but is not limited to, autograft, allograft or xenograft of fascia lata and / or throraco-lumbar fascia; natural and / or manmade polymeric fiber; fibrous tissue inducers such as: talc, pharmaceuticals and / or minerals; fibrous tissue morphogenic protein produced by recombinant DNA technology and / or notochord cells from stem cell technology and / or any combination thereof.

[0035]FIG. 2 depicts another embodiment of the device 10 as a tangled knot of suitable fibrous tissue promoting fibers 16. In yet another embodiment, the device is multiple fabric bands made of suitable fibrous tiss...

Abstract

The present invention is a system for a partially biological disc replacement that stimulates natural fibrous, cartilaginous or other tissue growth in the DDD cavity, resulting in a partial biological disc replacement. Multiplicities of fibronous pieces of fibro-cartilaginous tissue promoting material are inserted into the DDD cavity inducing tissue growth. The fibro-cartilaginous tissue

Description

FIELD OF THE INVENTION [0001] The present invention relates generally to the field of systems adapted to replacing or assisting bone of a natural vertebral column of a living body. More specifically, the present invention relates to a system that surgeons can use to construct a semi-biological nuclear replacement that will replace the diseased nucleus and ultimately function in a manner similar to a natural disc nucleus. BACKGROUND OF THE INVENTION [0002] Low back pain is a condition affecting millions of humans. This syndrome causes great personal, economic and social hardship. Resultant consequences to family members, co-workers and the community are significant. [0003] Scientific evidence indicates that the symptoms of low back pain are most commonly caused by degenerative pathology in the spinal motion segment. The spinal motion segment consists of a unit of spinal anatomy bounded by two vertebral bodies that includes the two vertebral bodies and the interposed intervertebral di...
