Regulatory Classification

Identification

Single/multiple component metallic bone fixation appliances and accessories are devices intended to be implanted consisting of one or more metallic components and their metallic fasteners. The devices contain a plate, a nail/plate combination, or a blade/plate combination that are made of alloys, such as cobalt-chromium-molybdenum, stainless steel, and titanium, that are intended to be held in position with fasteners, such as screws and nails, or bolts, nuts, and washers. These devices are used for fixation of fractures of the proximal or distal end of long bones, such as intracapsular, intertrochanteric, intercervical, supracondylar, or condylar fractures of the femur; for fusion of a joint; or for surgical procedures that involve cutting a bone. The devices may be implanted or attached through the skin so that a pulling force (traction) may be applied to the skeletal system.

Dear Matt Corbett:

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 (the 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 available 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.

Device Description:

The AlphaVent Knotless SP Biocomposite Anchors (herein referred to as the subject device(s)) are bone anchors with a screw-in mechanism. The subject device is comprised of a poly-ether-ether-ketone (PEEK) eyelet and a biocomposite (Poly-L-lactic Acid (PLLA)/beta-tricalcium phosphate ( $\beta$ -TCP)) anchor body, pre-assembled onto a disposable stainless-steel inserter, which enables insertion of the anchor into bone either via a self-punching mechanism or after creation of a pilot hole. The devices are single use, provided sterile, and are packaged in sterile barrier systems (SBS).

Indications for Use:

The AlphaVent Knotless SP Biocomposite Anchor is intended to be used for soft-tissue to bone fixation in the shoulder, foot and ankle, knee, hand and wrist, elbow, and hip in skeletally mature pediatric and adult patients. It is indicated for use in the following procedures:

Shoulder: Rotator Cuff Repair, Bankart Repair, SLAP Lesion Repair, Biceps Tenodesis, Acromio-clavicular Separation Repair, Deltoid Repair, Capsular Shift or Capsulolabral Reconstruction

## Comparison of Technological Characteristics with the Predicate Device:

The AlphaVent Knotless SP Biocomposite Anchor is a line extension of Predicate A and is identical in terms of design, intended use, indications for use, and implantation technique and equivalent in terms of other technological characteristics and performance attributes. It is identical to Predicate B in terms of in terms of intended use, indications for use, raw material intended for implantation, general anchor system design features. It is equivalent in terms of other technological characteristics and performance attributes. Any minor differences between the subject and predicate devices do not raise new questions of safety or effectiveness. Therefore, based on the criteria described in 21 CFR §807.100, the AlphaVent Knotless SP Biocomposite Anchor is substantially equivalent to the identified predicate devices.

## Performance Testing:

Non-clinical benchtop testing was performed to evaluate the performance characteristics of the AlphaVent Knotless SP Biocomposite Anchor, including ultimate tensile strength (UTS) and insertion performance. The proposed device demonstrated statistically equivalent or higher UTS compared to the predicate devices immediately after insertion, following cyclic loading, and after accelerated degradation at multiple time points through the anticipated duration of healing. Additionally, successful insertion was confirmed under worst-case conditions. Bacterial endotoxin testing was also performed on the AlphaVent Knotless SP Biocomposite Anchor, with passing results below the required limits. The results support that the AlphaVent Knotless SP Biocomposite Anchor raises no new questions of safety or effectiveness and is substantially equivalent to the predicate devices.

## Conclusions:

The information presented within this Traditional 510(k) demonstrates that the AlphaVent Knotless SP Biocomposite Anchors are substantially equivalent to the predicate devices, and will perform as safely and effectively within the intended use.
