Intended Use

The MedicineLodge ZipKnot™ is indicated for use in approximation and/or ligation of soft tissues using USP #2 braided polyethylene surgical suture.

Device Story

The MedicineLodge ZipKnot™ is a suture fixation device used in open and endoscopic surgery. It consists of a PEEK button threaded with USP #2 braided polyethylene suture, housed in a polypropylene threader pod. The button features a series of holes designed to allow one-way suture movement, locking the suture when pulled in the opposite direction. During surgery, the device is advanced down suture arms using standard sliding knot techniques; excess suture is trimmed after placement. The device is intended for use by surgeons to secure soft tissue approximation or ligation, potentially simplifying knot-tying procedures and improving surgical efficiency.

Clinical Evidence

Bench testing only. Device is biocompatible per ISO-10993 and G95-1. Sterility validated to SAL 10^-6 per EN 552 (Gamma) or EN 550 (Ethylene Oxide).

Technological Characteristics

Materials: PEEK button, polypropylene threader pod, USP #2 braided polyethylene suture. Mechanism: One-way locking suture button. Sterilization: Gamma irradiation (EN 552) or Ethylene Oxide (EN 550). Packaging: Double Tyvek pouch (ASTM 4169). Biocompatibility: ISO-10993, G95-1.

Indications for Use

Indicated for approximation and/or ligation of soft tissues in patients requiring surgical suture fixation.

Dear Ms. Sinnott:

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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such 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); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

#### Summary

This summary of 510(k) safety and effectiveness is being submitted in accordance with requirements of SMDA 1990.

The MedicineLodge ZipKnot™ is indicated for use in approximation and/or ligation of soft tissues using USP #2 braided polyethylene surgical suture.

The MedicineLodge ZipKnof™ consists of a Polyetheretherkeytone (PEEK) button threaded with high strength polyethylene suture Threaders and housed in a polypropylene Threader Pod. The suture Situngal portytene sattre through a series of holes in the ZipKnot™. The holes are designed in such as way as to allow suture to be pulled through the button in one direction but lock the suture if pulled in the opposite direction. Once suture is threaded through the button it can be advanced down the suture arms using the same techniques used in both open and endoscopic surgery when tying sliding surgical knots. Once the ZipKnot™ is in place the excess suture ends are trimmed.

The MedicineLodge ZipKnot™ will be provided sterile for single-use (ASTM 4169), packaged individually in a double tyek pouch. The device will be sterilized by Gamma irradiation (EN 552) or Ethylene Oxide (EN550) including limits for Ethylene Oxide residuals and validated to a sterility assurance level (SAL) of 106. The device is biocompatible per ISO-10993 and G95-1.

The MedicineLodge ZipKnot™ is equivalent in intended use, safety, and efficacy to the predicate device. The subject device was shown to have substantially equivalent performance when compared to the predicate device.

The MedicineLodge ZipKnot™ is considered substantially equivalent to Smith & Nephew ULTRABRAID™.
