SI-BONE, Inc., a medical device company, develops procedural solutions for compromised bone, grounded in expertise in biomechanical design and anatomy-specific applications in the United States and internationally. It offers a series of patented titanium implants and the instruments used to implant them, as well as implantable bone products. The company also provides IFUSE, a triangular titanium implant with a triangular cross-section and porous surface that stabilizes the joint and facilitates the biological fixation of the bone onto the implant to drive fusion; IFUSE 3D, a triangular titanium implant with a porous surface and fenestrated design to self-harvest bone; IFUSE BONE, which supports and augments the patient's own bone tissue in orthopedic procedures; IFUSE TORQ, an additively-manufactured threaded implant designed to allow for osteointegration, or incorporation of the bone into the implant's porous surface and structure; IFUSE BEDROCK GRANITE, an implant with a machined titanium core and a tulip that attaches to the rod and provides fusion and fixation to the sacroiliac joint as a foundational element for segmental spinal fusion; and IFUSE TORQ TNT, a porous threaded design with lengths capable of spanning the posterior pelvis, passing through the ipsilateral ilium, sacrum, and through the contralateral ilium. The company markets its products primarily with a direct sales force, as well as through third-party sales agents and resellers.
