About
The objective of this study is to evaluate the safety and performance of the Discure System therapy in subjects with early to moderate degeneration of the disc (DDD).
Full description
A prospective, interventional, multi-center, single arm, open label, feasibility study. The study is designed to evaluate the safety and performance of the Discure System in the treatment of chronic low back pain (with or without radicular pain) of discogenic origin with early to moderate degeneration of the disc (DDD) in levels L1-2 to L5-S1, as confirmed by history and radiographic studies and/or discography, who failed conservative treatment of 12 weeks in duration.
Subjects will be followed at 1,3-, and 6-months post procedure. The primary endpoint will be assessed at the 6-month follow-up visit.
The study will enroll up to 20 subjects at up to 8 sites.

Back Pain characteristics:
Source of pain is the sacroiliac joint or facet joint as determined by the Investigator.
Any prior diagnosis of lumbar vertebral compression fracture, lumbar pars fracture, or lumbar annular tear with disc protrusion of the target operative disc, that is surgical.
Participant has lumbar spondylitis or other undifferentiated spondyloarthropathy at the target disc.
Participant has had previous lumbar spine surgery at level L1-2 to L5-S1
Participant has had previous disc invasive treatment procedures, into the target disc/s, except for contrast media-discography performed at least 2 weeks prior to study enrollment.
Participant has symptomatic involvement of more than two lumbar discs or more than two lumbar discs that satisfy the radiographic profile defined in the Inclusion Criteria
Participant has current infection at the planned procedure site, active systemic infection, or current or prior history of lumbar spinal infection (i.e., discitis, septic arthritis, epidural abscess)
Participant is at higher risk for post-surgical infection (e.g., taking immunosuppressants, has a severe infection or a history of serious infection)
Participant has an active malignancy or tumor.
Participant has had significant systemic disease, such as unstable angina, autoimmune disease, rheumatoid arthritis, diabetes mellitus-insulin dependent, or muscular dystrophy.
Participant has a congenital or acquired coagulopathy or thrombocytopenia.
