Biocompatibility testing performed per ISO 10993-1:2009, including cytotoxicity, intracutaneous reactivity, sensitization, endotoxin, and material-mediated pyrogenicity. Shelf-life validated via accelerated and real-time aging per ASTM F1980.

Technological Characteristics

Material: High-density polytetrafluoroethylene (PTFE). Form: Monofilament, uncoated, non-absorbable. Sizes: 2-0 to 6-0. Sterilization: Ethylene Oxide (EO). Compliance: USP <861> (diameter), USP <871> (needle attachment), USP <881> (tensile strength). Biocompatibility: ISO 10993-1:2009 (implant, permanent contact).

Indications for Use

Indicated for soft tissue approximation and/or ligation in dental and general surgery patients.

Regulatory Classification

Identification

Dear Ms. Sanchez:

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.
