NLT Spine (Kfar Saba, Israel), a maker of minimally invasive spinal technologies, has received FDA approval for the second generation of the PROW FUSION implant and eSPIN discectomy tool. The two devices help to perform lumbar interbody fusion via a small posterior incision in a reliable, safe and minimally invasive procedure. The second generation products make use of fewer instruments, better irrigation, improved material and optimized design.
The PROW FUSION interbody fusion implant, which is used for Transforaminal Lumbar Interbody Fusion (TLIF) procedures, consists of a segmented non-linear structure that is implanted in a straight configuration using a protective conduit. The conduit is pre-inserted using a keyhole incision. When the implant reaches the intervertebral space it takes up a circular form thereby forming a footprint larger than competing technologies. This larger footprint results in larger bone graft volume within the implant.
The eSPIN Discectomy System is used during discectomy for fusion procedures in L2-S1 spinal segments in order to cut and grind intervertebral disc material. The system comes with single use cutting tips, a hand-held instrument, a motor adaptor and a range of access and positioning instruments. Use of the eSPIN system results in removal of 67% more disc volume compared to competing procedures, and 83% fewer passes of the instrument near the exiting nerve. The eSPIN and PROW FUSION systems are designed to be used during minimally invasive spine surgery with spinal fixation systems such as posterior pedicle screw and rod systems.
