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. Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download). Your device is also subject to, among other requirements, the Quality System (QS) regulation (21 CFR Part 820), which includes, but is not limited to, 21 CFR 820.30. Design controls; 21 CFR 820.90. Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review, the QS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181). 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 Part 803) for devices or postmarketing safety reporting (21 CFR Part 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 Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050. All medical devices, including Class I and unclassified devices and combination product device constituent parts are required to be in compliance with the final Unique Device Identification System rule ("UDI Re"). The UDI Rule requires, among other things, that a device bear a unique device identifier (UDI) on its label and package (21 CFR 801.20(a)) unless an exception or alternative applies (21 CFR 801.20(b)) and that the dates on the device label be formatted in accordance with 21 CFR 801.18. The UDI Rule (21 CFR 830.300(a) and 830.320(b)) also requires that certain information be submitted to the Global Unique Device Identification Database (GUDID) (21 CFR Part 830 Subpart E). For additional information on these {2}------------------------------------------------ requirements, please see the UDI System webpage at https://www.fda.gov/medical-device-advicecomprehensive-regulatory-assistance/unique-device-identification-system. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97).

DEVICE DESCRIPTION Secret Line up and i-Thread (Sterile single use absorbable polydioxanone suture with needle) consist of a cannula type needle which is straight and hollow (pre-loaded on the suture), a needle cap, a hub, a sponge and polydioxanone (PDO) suture which is sterilized by ethylene oxide (EO) gas. The pigment for the violet dye is D&C Violet No.2. PDO Sutures are characterized by their bidirectional barbs along axis of the monofilament. The bidirectional barbs of barbed suture are precisely lodged in tissue, making it feasible to anchor in the tissue and prevent movement in both directions without the need for a surgical knot. As a result, the barbed suture improves the effectiveness of treatment. #### V. INDICATIONS FOR USE Secret Line up and i-Thread (Sterile single use absorbable polydioxanone suture) comprised of dyed polydioxanone suture with a sterile needle. It is indicated for use in soft tissue approximation where use of absorbable suture is appropriate. The suture is not intended for body cavity applications, nor is it intended for lifting and supporting tissues; it is intended for dermatological use only. #### VI.

The Subject device has the same intended use as that of the predicate device. There is minor difference between the two devices where it is indicated "similar", in all other cases it is seen that the subject stays as "Substantial Equivalent" to that of the predicate device characteristics. Differences observed from the above table are with respect to suture length. Despite this difference, it is {10}------------------------------------------------ witnessed from the test results submitted as part of 510(k) that the subject device is substantially equivalent to the predicate device in terms of safety and effectiveness and there is no difference in terms of intended clinical application. Additionally, the subject device is substantially equivalent to the capacity and function of the predicate device. #### VIII. PERFORMANCE TESTING Performance testing was conducted on the subject device to prove that all the design specifications are substantially equivalent to the predicate device.
