Nano implants for the spine get FDA approval
Nano implant technology developed by BMES Fellow Thomas Webster and BMES member Chang Yao has been been cleared by the FDA, according to Nanovis, the company producing the tehcnoloy.Nanovis, announced the successful FDA clearance of its FortiCore TLIF and PLIF interbodies featuring a Nanosurface-enhanced deeply porous titanium scaffold intermolded with a PEEK core.
“Implant nano surface science has advanced from the early days when we simply created nanoroughness for implants because tissues have nanoroughness," Webster said. "Now we understand the mechanisms by which nanotopographies can interact with cellular signaling pathways. I'm delighted that with Nanovis' implants, patients can now benefit from a carefully designed and controlled nanotopography that harnesses this groundbreaking research.” Webster is the Chemical Engineering Department Chair at Northeastern University.
Webster and Yao were early pioneers in the use of nanosurfaces to enhance bone growth.
FortiCore interbodies have deeply porous interconnected titanium scaffolds intermolded with a PEEK core, giving surgeons important fixation and imaging advantages. Data comparing the osseointegration strength of the FortiCore scaffold, PEEK, and allograft to the strength of trabecular host bone was published in Spine in late 2016. Now the titanium scaffolds on the FortiCore TLIF and PLIF interbodies are enhanced with a carefully designed and controlled nanosurface, according to the announcement.
