## Intended Use

The Tenon Medical Catamaran Sacroiliac Joint Fixation System (CAT SIJ Fixation System) is intended for sacroiliac joint fusion for conditions including sacroiliac joint disruptions and degenerative sacroiliitis.

## Device Story

The Catamaran SIJ Fixation System is a metallic bone fixation device designed for minimally invasive sacroiliac joint fusion. The system comprises a titanium implant featuring two hollow barrels connected by a bridge, alongside specialized surgical instruments (access, drill/delivery, accessory, and extraction sets). During surgery, autologous bone graft is packed into the implant barrels to promote stabilization. The device is intended for single-use and requires steam sterilization by the user prior to the procedure. It provides a mechanical means to stabilize the sacroiliac joint, facilitating fusion to address joint disruptions and degenerative sacroiliitis. The system is used by surgeons in a clinical/OR setting.

## Clinical Evidence

No clinical data provided. Evidence consists of bench testing, including biocompatibility, chemical characterization, mechanical static and dynamic shear testing, pull-out testing, and cadaveric/instrumentation testing.

## Technological Characteristics

Titanium implant; two hollow barrels connected by a bridge; available in 7.5mm/10mm diameters and 30mm/40mm lengths. Mechanical fixation device. Provided clean and non-sterile; requires steam sterilization. Standalone surgical system.

## Regulatory Identification

A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.

Dear Ms. Cecka:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820);
