Schlieren (Zurich), Switzerland, March 13, 2019 – Kuros Biosciences (SIX: KURN) today announced that its Dutch subsidiary, Kuros Biosciences BV, has received clearance for the Kuros TLIF cage from the U.S. Food and Drug Administration (FDA).

About the Kuros TLIF Cage

The Kuros TLIF Cage is intended for use in intervertebral body fusion of the spine. The Kuros TLIF cage is inserted via a posterior approach and can be used in one level or two contiguous levels of the lumbar spine (L1 to S1). The Kuros TLIF cage is designed for use with autograft and/or allograft comprised of cancellous and/or corticocancellous bone graft to facilitate fusion, and is to be used with supplemental posterior spinal fixation systems for use in the lumbar spine that are cleared by the FDA.
