Intended Use

The PEEK SINEFIX is intended for soft tissue to bone reattachment in rotator cuff repairs for tendon ruptures up to 2 cm.

Device Story

SINEFIX is a PEEK implant system for re-attaching ruptured rotator cuff tendons to the humerus. The device comprises a baseplate, a medial anchor, and a lateral anchor. During surgery, the baseplate is positioned over the tendon; the medial anchor is driven through the tendon into the bone, and the lateral anchor is secured directly into the bone lateral to the tendon. Used by orthopedic surgeons in clinical settings to facilitate healing of the bone-tendon interface. The device provides mechanical fixation of the tendon to the humerus, supporting the natural healing process.

Clinical Evidence

No clinical data. Substantial equivalence is supported by non-clinical bench testing, including insertion testing, ASTM F543-17 pullout testing (static and post-cyclic loading), and static tensile testing. Biocompatibility was evaluated per ISO 10993-1, and sterilization validation was performed per ISO 11137-1/2 to achieve a SAL of 10^-6.

Technological Characteristics

Implant material: PEEK. System components: baseplate, medial anchor, lateral anchor. Mechanical fixation principle. Testing standards: ASTM F543-17 (pullout), ISO 10993-1 (biocompatibility), ISO 11137-1/2 (sterilization), ISO 11607-1/2 (packaging). Sterilization: Gamma radiation (SAL 10^-6).

Indications for Use

Indicated for soft tissue to bone reattachment in rotator cuff repairs for tendon ruptures up to 2 cm.

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 Dr. Springer:

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 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for

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

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).

#### Description of the Device 4.

The SINEFIX is a PEEK implant which can be used to re-attach a ruptured rotator cuff tendon to the humerus of the shoulder. The implant can be used to re-attach complete or partially ruptured tendons up to 2 cm to facilitate the healing of the natural bone-tendon interface. The implant consists of a baseplate with a lateral and a medial anchor. The baseplate is placed over the tendon and attached to the humerus with the anchors. The medial anchor goes through the tendon, while the lateral anchor goes directly into the bone, lateral of the tendon.

#### 7. Summary of Performance Data and Design Controls

The SINEFIX has the same technological characteristics as the predicate devices including design, intended use and material composition.

The SINEFIX has been subject to non-clinical testing, including:

- Insertion testing
- ASTM F543-17 Pullout testing
- ASTM F543-17 Pullout testing after cyclic loading
- Static tensile test
- Dynamic testing pullout strength after cyclic loading
- . Pyrogenicity and endotoxins

In accordance with the guidance for Industry and FDA Staff: Bone Anchors - Premarket Notification (510(k)) Submissions, March 3, 2020.

- . Packaging testing was performed in accordance with ISO 11607-1/2 and has proven a shelf life of 5 years;
- Biological evaluation was performed in accordance with ISO 10993-1 and the Guidance for Industry and FDA Staff - Use of International Standard ISO 10993, "Biological evaluation of medical devices – Part 1: Evaluation and testing within a risk management process", September 4, 2020;
- . Sterilization validation was performed in accordance with ISO 11137-1/2 and has proven a SAL 10-6:
- . Reprocessing validation was performed for the cleaning, disinfection, steam sterilization and drying of the reusable surgical instruments in accordance with the Guidance for Industry and FDA Staff - Reprocessing Medical Devices in Health Care Settings: Validation Methods and Labeling, March 17, 2015;

Results of the performed tests demonstrate that the SINEFIX are substantially equivalent to legally marketed predicate devices.

#### 8. Conclusion of Substantial Equivalence

The purpose of the traditional 510(k) is to receive regulatory clearance to introduce the SINEFIX to interstate commerce. Substantially equivalence has been demonstrated to the cited predicate device.
