Problems solved by technology

Additionally, transosseous delivery of therapeutic material through the endplates of the vertebral bodies avoids damage to the outer annulus; however, this method of delivery may affect the endplates, which provide the primary source of oxygen and nutrients to the nearly avascular disc

Abstract

An approach is provided for delivering therapeutic materials to an intervertebral disc via a sub-ligamentous space. The approach includes positioning a tool at an interface of a longitudinal ligament and an outer surface of the intervertebral disc, in which the interface is the sub-ligamentous space. The tool may include a first needle and a second needle housed within the first needle. An insertion end of the first needle may include a shallow beveled end. The approach includes inserting the insertion end of the first needle into the sub-ligamentous space. The approach includes deploying the second needle from within the first needle into at least one of an annulus and a nucleus of the intervertebral disc. The approach includes delivering the therapeutic materials to the at least one of the annulus and the nucleus.

Description

Background technique [0001] Human spines may show increasing signs of degeneration as humans age. Typically, early stages of spinal degeneration can be treated with conservative care, while advanced stages of spinal degeneration may involve structural changes in the spine that require fusion surgery. However, patients in intermediate stages of spinal degeneration often suffer from painful disc degeneration that does not respond to conservative care, leaving patients few options for addressing their discogenic pain. [0002] In recent years, several regenerative therapies and treatments have been developed to aid in the biological and chemical recovery of degenerated intervertebral discs. In these therapies and treatments, therapeutic materials may be delivered to the disc to address discogenic pain and / or degenerative changes in the annulus fibrosus (and specifically the nucleus pulposus of the disc). [0003] Delivery of the therapeutic material to the disc requires punctur...
