Intended Use
WEGO-PDO Barbed Suture is indicated for soft tissue approximation where use of an absorbable suture is appropriate.
Device Story
WEGO-PDO Barbed Suture is a monofilament, absorbable surgical suture composed of poly(p-dioxanone). The device features small unidirectional or bidirectional barbs along its length, allowing for tissue approximation without the need for surgical knots. It is provided sterile, single-use, and may be supplied with or without stainless steel needles of various types (Taper, Reverse Cutting, Cutting, Taper Cutting, Blunt, Diamond). The device is used by clinicians for soft tissue approximation. The barbs secure the suture within the tissue, eliminating knot-tying requirements, which simplifies the closure process and potentially benefits the patient by reducing procedure time and tissue trauma. The device is available in various lengths, diameters (USP 5-0 to USP 2), and colors (dyed or undyed).
Clinical Evidence
No clinical study is included in this submission. Bench testing only.
Technological Characteristics
Material: poly(p-dioxanone) suture; stainless steel needles. Design: monofilament, barbed (unidirectional/bidirectional). Sterilization: Ethylene Oxide (EO) to SAL 10^-6.

Dear Diana Hong:
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.

#### SE Analysis 1 - Indications for Use
The indications for use of Predicate device 1 and Predicate device 2 includes the material (Polydioxanone) of suture. Although the indications for use of Proposed Device does not include the material of suture, the suture's material of Proposed Device is also Polydioxanone. Therefore, this item is considered to be substantially equivalent.
#### SE Analysis 2- Welded Loop
The manufacture method and length of proposed device's and predicate device's welded loop are same. Although the purpose of proposed device's and predicate device's welded loop is different, the proposed suture and predicate suture have the same material, technological characteristic, and intended use. Therefore, this item is considered to be substantially equivalent.
#### SE Analysis 3- Color
The suture of Predicate Device 1 and Predicate Device 2 is dyed. The suture of Proposed Device is available in undyed and dye. The color of Proposed Device 1 and Predicate Device 1 and Predicate Device 2's suture is dyed with D&C Violet No. 2. The Proposed Device has more undyed suture than the Predicate Device 1 and Predicate Device 2. The test reports for the undyed suture of Proposed Device provided in this submission, including performance test, and stability demonstrates that the undyed Proposed Device complied with the requirements of USP Absorbable Surgical Suture. Therefore, this item is considered to be substantially equivalent.
#### SE Analysis 4- Type of barbs
The barbs of Proposed Device include uni-directional barb and bi-directional barbs. The uni-directional barb of Proposed Device is same with the barb of Predicate Device 1. The bi-directional barb of Proposed Device is same with the barb of Predicate Device 2. Therefore, this item is considered to be substantially equivalent.
#### SE Analysis 5- Suture Size
The suture sizes of Proposed Device and Predicate Device 2 are both identified in the currently recognized United States Pharmacopoeia; although the range of suture size of Proposed Device is more than that of the Predicate Device 2, the suture sizes of Proposed Device comply with the requirements listed in USP Monograph for Absorbable Surgical Suture. Additionally, the proposed suture and predicate suture have the same material, technological characteristic, and intended use. Therefore, this item is considered to be substantially equivalent.
#### SE Analysis 6- Suture Length
The requirements for suture length of Proposed Device and Predicate Device 1 and Predicate Device 2 are both identified in the currently recognized United States Pharmacopoeia; although we do not know the exact suture length of Predicate Device 1 and Predicate Device 2, the suture lengths of Proposed Device comply with the requirements listed in USP Monograph for Absorbable Surgical Suture. Additionally, the proposed suture and predicate suture have the same material, technological characteristic, and intended use. Therefore, this item is considered to be substantially equivalent.
#### SE Analysis 7- Needle Biocompatibilitv
{10}------------------------------------------------
The needle biocompatibility of Proposed Device and Predicate Device 1 and Predicate Device 2 are should meet the requirements of ISO10993 series standards; although we do not know the specific test items of Predicate Device 1 and Predicate Device 2, but the needle biocompatibility tests of Proposed Device have been performed in Cytotoxicity, Sensitization and Intracutaneous Reactivity Test. These studies can demonstrate the needle biocompatibility of Proposed Device. Therefore, this item is considered to be substantially equivalent.
## SE Analysis 8- Suture Biocompatibility
The biocompatibility of Proposed Device and Predicate Device 1 and Predicate Device 2 meet the requirements of ISO10993 series standards; although we do not know the specific test items of Predicate Device 1 and Predicate Device 2, the biocompatibility tests of Proposed Device have been performed in Cytotoxicity, Max Sensitization, Intracutaneous Reactivity Test, Acute Systemic Toxicity Test, Genotoxicity, Pyrogenicity, Muscle Implantation Study, Sub chronic Toxicity Study, Hemolysis Test (Direct Contact) and Hemolysis Test (Indirect Contact). These studies can demonstrate the biocompatibility of Proposed Device. Therefore, this item is considered to be substantially equivalent.
#### 9. Substantially Equivalent (SE) Conclusion
Based on the comparison and analysis above, the proposed devices are determined to be Substantially Equivalent (SE) to the predicate device.
