Intended Use

The Entasis 3D Dual-Lead Sacroiliac Implant System is intended for sacroiliac joint fusion for conditions including degenerative sacroilitis and sacroiliac joint disruptions, to augment immobilization of the sacrolliac joint in skeletally mature patients undergoing sacropelvic fixation as part of a lumbar or thoracolumbar fusion and acute, nonacute, and non-traumatic fractures involving the sacroiliac joint. This includes those whose symptoms began during pregnancy or in the peripartum period and have persisted postpartum for more than 6 months.

Device Story

System consists of additive and machined dual-lead sacroiliac screws and optional washers; designed for sacroiliac joint fusion and stabilization. Implants manufactured from titanium alloy (Ti-6Al-4V or Ti-6Al-4V ELI). Used by surgeons in clinical settings to provide mechanical fixation and load-bearing support across the sacroiliac joint. Device aids in immobilization during fusion procedures; helps restore joint stability; potentially reduces pain and improves patient mobility by facilitating fusion.

Clinical Evidence

Bench testing only. Testing included static torsion, driving torsion, pullout, and static/dynamic cantilever bending per ASTM F3574 and ASTM F3547 standards. Results demonstrate mechanical strength sufficient for intended use.

Technological Characteristics

Materials: Titanium alloy (Ti-6Al-4V) per ASTM F3001 or (Ti-6Al-4V ELI) per ASTM F136. Dimensions: 30-110 mm length, 7-14.5 mm diameter. Design: Dual-lead screws with optional washers. Mechanical fixation principle. No software or energy source.

Indications for Use

Indicated for skeletally mature patients requiring sacroiliac joint fusion due to degenerative sacroiliitis, sacroiliac joint disruptions, sacropelvic fixation during lumbar/thoracolumbar fusion, or acute/non-acute/non-traumatic sacroiliac joint fractures. Includes patients with symptoms originating during pregnancy or peripartum persisting >6 months postpartum.

Regulatory Classification

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 Nathan Wright:

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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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

{1}------------------------------------------------

801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4. Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).
