Intended Use

The PDS Barbed Surgical Suture is indicated for use in soft tissue approximation where use of absorbable sutures is appropriate. The anatomical location(s) of use are on the skin for dermatological applications only. The suture is not intended for interior body cavity applications and the suture is not intended for lifting and supporting tissues.

Device Story

PDO MAXX Threads are absorbable polydioxanone (PDO) monofilament sutures with cut barbs; preloaded in 19G/100 mm blunt needle cannula. Used by clinicians for soft tissue approximation in dermatological applications. Barbs allow tissue embedding without surgical knots. Device is sterile, single-use, and non-powered. Clinical benefit derived from secure tissue approximation without knot tying.

Clinical Evidence

No clinical data. Evidence provided via bench testing (biocompatibility, tensile strength, dimension, absorption, needle performance) and in vivo biodegradation study in Sprague-Dawley rats.

Technological Characteristics

Material: Polydioxanone (PDO) with D&C Violet No. 2 colorant. Form: Monofilament with cut barbs, USP 0 diameter, USP 2-0 tensile strength, 150 mm length. Delivery: Pre-loaded in 19G/100 mm blunt needle cannula. Energy source: None. Sterilization: Not specified.

Indications for Use

Indicated for soft tissue approximation in dermatological applications requiring absorbable sutures. Not for interior body cavity use or tissue lifting/support.

Regulatory Classification

Identification

An absorbable polydioxanone surgical suture is an absorbable, flexible, sterile, monofilament thread prepared from polyester polymer poly (p-dioxanone) and is intended for use in soft tissue approximation, including pediatric cardiovascular tissue where growth is expected to occur, and ophthalmic surgery. It may be coated or uncoated, undyed or dyed, and with or without a standard needle attached.

Special Controls

*Classification.* Class II (special controls). The special control for the device is FDA's “Class II Special Controls Guidance Document: Surgical Sutures; Guidance for Industry and FDA.” See § 878.1(e) for the availability of this guidance document.

Dear Ms. Vater:

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.

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

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 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).

#### IV. DEVICE DESCRIPTION

PDO MAXX THREADS™ barbed sutures are made of polydioxanone (PDO) and have the colorant D&C Violet No. 2 (21 CFR 74.3602). The sutures are USP 0 suture in diameter and USP 2-0 suture in tensile strength, and 150 mm in length, swaged to a 19G/100 mm "L" Blunt needle and preloaded in a needle cannula. The sutures are inserted into the cannula/needle. The barbed sutures have cut barbs along the axis of the monofilament that allows the suture to embed in the tissue after the surgeon has placed it; therefore, there is no need to tie a surgical knot. The sutures are absorbable in the body.

#### V. INDICATIONS FOR USE

The PDS Barbed Surgical Suture is indicated for use in soft tissue approximation where use of absorbable sutures is appropriate. The anatomical location(s) of use are on the skin for dermatological applications only.

The suture is not intended for interior body cavity applications and the suture is not intended for lifting and supporting tissues.
