Tenon Medical, Inc. develops surgical implant systems, including the CATAMARAN SIJ Fusion System, to improve sacroiliac joint fixation and fusion outcomes, serving the U.S. and Puerto Rico since 2012.

Tenon Medical's Catamaran SE is a minimally invasive SI joint fusion implant with a smaller profile, providing surgeons versatility for diverse anatomies and revisions in the expanding SI joint market.
In March 2025, Tenon Medical experienced a massive stock surge of over 315% in a single day. This significant investor interest was fueled by two major positive developments: receiving FDA clearance for an expanded indication of its Catamaran SI Joint Fusion System for use as an augmentation to thoracolumbar fusion, and the grant of new patents by the European Patent Office for its Catamaran SI Joint Fixation Device.
In a pivotal strategic move, Tenon Medical completed the acquisition of SiVantage, a decision aimed at diversifying its product portfolio and expanding its commercial footprint. The company's leadership indicated this was a significant focus and led to a strategic shift in its commercial initiatives in anticipation of the deal's closing.
