|Medtronic Launches the Divergence(TM) Anterior Cervical Fusion System|
System Offers New Approach to Single-Level ACDF Procedures
MEMPHIS, TENN. - October 21, 2014 - Medtronic, Inc. (NYSE: MDT) announced the U.S. launch of the DIVERGENCE(TM) Anterior Cervical Fusion System for the treatment of single-level cervical disc disease today at the 2014 Congress of Neurological Surgeons (CNS) Annual Meeting in Boston.
The DIVERGENCE(TM) System represents a new approach to one-level anterior cervical discectomy with fusion (ACDF) procedures, which traditionally use a four-hole plate and interbody fusion cage. With the DIVERGENCE(TM) System, the plate and interbody cage can be inserted simultaneously using a common set of instrumentation and one surgical technique. Traditional cervical fusion surgery requires a two-step insertion technique for the plate and interbody cage, and each implant requires its own set of instruments and its own surgical technique.
In addition, the DIVERGENCE(TM) System incorporates a laterally-divergent screw insertion technique, which requires less retraction compared to the traditional medially-convergent screw insertion techniques used with other anterior cervical plating systems.
In a 2013 edition of The Spine Journal, Dong-Ho Lee and colleagues published an article entitled "Anterior Cervical Plating Technique to Prevent Adjacent-Level Ossification Development." The study concluded that ACDF patients with plates placed less than 5mm from the adjacent level disc have statistically significant increases in the frequency and severity of adjacent-level ossification disease (ALOD), a condition in which osteophytes (bone spurs) develop at the adjacent level and may become symptomatic. The article also demonstrated that short plates allow for increased screw angulation, longer screw placement, reduced incision size, minimized dissection of the anterior longitudinal ligament (ALL) and limited encroachment by the plate on adjacent-level discs. The DIVERGENCE(TM) System plates are offered in relatively short lengths of 15.5mm to 20.5mm, and are designed for use with hyper-angulated screw insertion techniques.
"The introduction of the DIVERGENCE(TM) Anterior Cervical Fusion System demonstrates Medtronic's commitment to improving how spinal fusions are performed around the world," said Doug King, president of the Spinal business and senior vice president at Medtronic. "Physicians and patients will benefit from having access to these low-profile implants and an insertion technique that makes the ACDF procedure more efficient for the surgeon and less invasive for the patient."
Risks of the DIVERGENCE(TM) Anterior Cervical Fusion System include but are not limited to early or late loosening of any or all components and the development of new radiculopathy, myelopathy or pain.
About the DIVERGENCE(TM) Anterior Cervical Fusion System
The DIVERGENCE(TM) Anterior Cervical Cage component is intended to be used for anterior cervical interbody fusion procedures in skeletally mature patients with cervical disc disease at one level from the C2-C3 disc to the C7-T1 disc. Cervical disc disease is defined as intractable radiculopathy and/or myelopathy with herniated disc and/or osteophyte formation on posterior vertebral endplates producing symptomatic nerve root and/or spinal cord compression confirmed by radiographic studies. This cage is to be used in patients who have had six weeks of nonoperative treatment. The DIVERGENCE(TM) Cage must be used with supplemental fixation. The DIVERGENCE(TM) Cage is also required to be used with autogenic bone graft and/or allogenic bone graft comprised of cancellous and/or corticocancellous bone graft and is to be implanted via an open, anterior approach.
The DIVERGENCE(TM) Anterior Cervical Fusion System incorporates the technology of Gary K. Michelson, MD.
