A subsidiary of WoodWelding SA, Zurich-based SpineWelding AG, has received clearance from the US Food and Drug Administration (FDA) for its Elaris Pedicle Screw System. According to a press release, the screw system uses WoodWelding’s patent-protected BoneWelding technology.

The screw system is intended to immobilize and stabilize spinal segments in skeletally mature patients in the treatment of several different diseases, including spondylolisthesis (slipping of vertebra), spinal stenosis (narrowing of the spinal column), and even a failed spinal fusion or spondylodese.

Part of the Elaris Pedicle Screw System, the Elaris Pin, is made of a biocompatible and fully bioreabsorbable material. It stabilizes the spinal segments that are being treated and is gradually metabolized into water and carbon dioxide.

The Stansstad based WoodWelding SA has been developing its technology over the past 12 years, processing porous materials with ultrasound in order to bond them. It began with using wood, but the technology has since been developed for applications in the medical field in an effort to offer innovative solutions for implants.
