TranS1 Inc. (TSON) Announces AxiaLIF 1L+ 510(k) FDA Clearance

WILMINGTON, N.C., March 24, 2011 (GLOBE NEWSWIRE) — TranS1 Inc. (Nasdaq:TSON), a pioneer in minimally invasive approaches to lumbar spine surgery, today announced the 510(k) clearance of the AxiaLIF^® 1L+ product line, an instrumentation and implant system for L5-S1 lumbar fusion.

The AxiaLIF 1L+ system represents the next generation of the original AxiaLIF 1L system first launched in 2005 that has a clinical history of over 10,000 implants. TranS1 will commence a limited market release immediately with the new implant and instrumentation and anticipates full commercial release in the second half of 2011.

“Our new AxiaLIF 1L+ system further demonstrates TranS1’s commitment to continuously advance our proprietary AxiaLIF core technology. The 1L+ system builds upon our successful 2L+ system launched last year,” stated Ken Reali, TranS1’s President and CEO. “The modular approach of the 1L+, coupled with the tapered tip design, allows for more precise distraction capabilities and improvement in pull out strength. Further, through our minimally invasive pre-sacral access, the 1L+ implant provides a biomechanically stable implant at the base of the spine.”

“I am particularly excited by the availability of the 1L+ implant,” commented Dr. James Billys from the Florida Orthopedic Institute. “The 1L+ represents a real advancement in the AxiaLIF technology that will allow me to manually distract the L5-S1 disc space providing even greater control of the procedure and ultimately a strong fusion outcome.”
