Intended Use

DemeDIOX Absorbable Surgical Suture is indicated for use in general soft tissue approximation including pediatric cardiovascular tissue where growth is expected to occur and ophthalmic surgery, but not for use in adult cardiovascular, microsurgery and neural tissue. These sutures are useful where absorbable suture with extended wound support (up to six weeks) is desirable.

Device Story

DemeDIOX is a sterile, monofilament, synthetic absorbable surgical suture composed of poly(p-dioxanone). It is designed for soft tissue approximation where extended wound support (up to six weeks) is required. The device features a modification from the predicate where the thread is wound around the needle, and a foam needle park is used to secure the needle; in some configurations (size 6-0, 5cm length), the thread is not attached to the needle. It is intended for use by surgeons in clinical settings. The device provides mechanical support to tissues during the healing process and is absorbed by the body over time. It is provided sterile for single use.

Clinical Evidence

No clinical trials were conducted. Substantial equivalence is supported by non-clinical bench testing, including biocompatibility testing per ISO 10993-1, and conformance to USP 41/40 requirements for synthetic absorbable sutures, including physical properties, diameter, length, extractable color, and sterility.

Technological Characteristics

Monofilament synthetic absorbable suture composed of polyester, poly(p-dioxanone). Meets USP monograph requirements for absorbable surgical sutures. Sterilized via Ethylene Oxide (EO). Available in dyed violet or un-dyed forms. Features a foam needle park for needle securement.

Indications for Use

Indicated for general soft tissue approximation, including pediatric cardiovascular tissue and ophthalmic surgery. Contraindicated for adult cardiovascular, microsurgery, and neural tissue.

Dear Ms. Hernandez:

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. 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); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

#### l. Conclusion:

DemeDIOX Absorbable Surgical Suture is composed of the same material as the predicated device Demetech Polydioxanone Absorbable Suture and has the same design being a sterile, flexible, monofilament absorbable thread meeting all the requirements of the United States Pharmacopeia with the exception of the needle attachment and knot pull. DemeTECH's material used was selected based on known biocompatibility (per ISO 10993) and established history of use in the surgical suture industry.

The biocompatibility data and the results of performance testing presented, demonstrate the substantial equivalence of DemeTECH DemeDIOX Absorbable Surgical Suture to that of the predicate devices. It further demonstrates conformance with the USP, ISO 10993 and FDA Guidance for Surgical Suture 510(k).
