Stryker Sahara Lateral 3D Spine Implant Cleared

FDA has cleared a Stryker 510(k) for its Sahara Lateral 3D Expandable Interbody System featuring Lamellar 3D Titanium Technology. The company says the 3D-printed lateral expandable fusion device “features passive expansion capabilities that are designed to allow surgeons to achieve up to 30 degrees of sagittal spinal correction in skeletally mature patients.” It also uses a passive expansion mechanism allowing the implant to either be adjusted from a lateral approach intraoperatively or adjusted passively in a staged posterior approach following osteotomy, it says.

The Lamellar 3D Titanium Technology process starts with a titanium powder, Stryker says, and the implants are “grown through the selective application of a high-energy laser beam, incorporating complex internal geometries and a roughened surface architecture. Roughened titanium surfaces have been shown to demonstrate increased protein expression in contrast to smooth titanium surfaces.”
