Tenon Medical, Inc.

Tenon Medical is a Los Gatos, California medical device company that built the Catamaran SI Joint Fusion System, a patented, less-invasive way to fuse the sacroiliac joint with a single titanium implant placed along an inferior-posterior trajectory. Founded in 2012 and public on the Nasdaq since 2022 (TNON), Tenon targets the often-overlooked SI joint, a frequent and hard-to-diagnose source of chronic lower-back pain. In 2025 it expanded into a multi-product sacro-pelvic platform by acquiring the SiVantage SImmetry technology portfolio.
