The device description and performance studies focus on the physical properties and biological safety of a surgical suture, with no mention of AI or ML.
No
A suture is used for approximation and ligation of tissues, which is a supportive function during healing, not a therapeutic intervention itself.
No
Explanation: The device is a surgical suture used for tissue approximation and ligation, not for diagnosing medical conditions.
No
The device description clearly states it is a "flexible, monofilament suture thread," which is a physical object, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for "general soft tissue approximation and/or ligation," which is a surgical procedure performed directly on a patient's body.
- Device Description: The device is a "flexible, monofilament suture thread" used for stitching tissue together.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens (like blood, urine, or tissue samples) outside of the body to provide information for diagnosis, monitoring, or screening.
IVD devices are used to perform tests on samples taken from the human body. This device is a surgical tool used within the body.

The subject device is substantially equivalent to predicate devices listed above.
D. Device Description
The subject device is a nonabsorbable, flexible, monofilament suture thread which is supplied sterile. It is composed of the long-chain, linear aliphatic polymers nylon 6 and/or nylon 6,6. It is indicated for general soft tissue approximation and/or ligation. It will be offered undyed, or dyed with the FDA listed colorants FD&C Blue No. 2 (in accordance with Title 21 CFR, §74.1102) or Logwood extract (in accordance with Title 21 CFR, §73.1410). It will be offered uncoated, and will be available with and without standard needles attached.
E. Intended Use
Dafilon® Nonabsorbable Polyamide Surgical Sutures are indicated for use in all types of general soft tissue approximation and/or ligation, including use in cardiovascular, ophthalmic, and neurological procedures.
F. Comparison to Predicate Devices
The subject Dafilon® Nonabsorbable Polyamide Surgical Suture is composed of the same material as are the predicate devices, that being the long-chain aliphatic polymers polyamide 6 and 6,6 (or nylon 6 and 6,6). Further, the subject device is offered undyed, and dyed with the same colorant as are the predicate devices, that being FD&C Blue No. 2 or Logwood extract, at concentrations within that allowed by federal regulations as defined in 21 CFR.
The subject device has the same design as do the predicate devices, being a sterile, flexible, monofilament thread which is offered in a variety of lengths and a range of diameters conforming with the requirements of U.S. Pharmacopoeia (U.S.P.) XXIII, and which is offered with or without one of a selection of standard needles attached. Further, as is the case with the predicate devices, the subject device conforms in all respects to the requirements of the Official Monograph for Nonabsorbable Surgical Suture in U.S.P. XXIII,
2
including Sutures -- Diameter, Sutures -- Needle Attachment, and Tensile Strength.
Physical properties of the subject device are substantially equivalent to those of the predicate devices, including fiber diameter, knot pull tensile strength, straight pull tensile strength, elongation, knot security, and needle attachment strength.
The subject device is manufactured in the same manner as the predicate devices, being produced from polyamide polymers via melt-spin and drawing operations considered standard in the fiber and suture industries. As such, the suture fiber from which the subject device is made has essentially the same physical and chemical properties, and hence, the same biocompatibility profile and in vivo performance characteristics, as do the predicate devices.
The subject device is packaged and sterilized in the same or equivalent manner, and has the same labeling claims, as do the predicate devices.
G. Summary of Non-Clinical Tests
Non-Clinical testing conducted on the subject device to demonstrate its substantial equivalence to predicate devices included physical testing for all parameters identified above and to prove conformance to the requirements of U.S.P., in vitro and in vivo biosafety studies, and one (1) and two (2) year implant studies in animals to demonstrate retention of tensile strength and safety.
H. Summary of Clinical Tests
(Not applicable)
I. Conclusions of Non-Clinical and Clinical Tests
The results of all testing demonstrated the substantial equivalence, if not superiority, of the subject device to one or more predicate devices.

Dear Mr. Reitzler:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices that were regulated as transitional devices and that have been reclassified into class II. Notice of this reclassification was published in the Federal Register on Friday, May 31, 1991 (Vol. 56, No. 105, Pages 24684 and 24685). A copy of this Federal Register can be obtained by calling the Division of Small Manufacturers Assistance (DSMA) at (800) 638-2041 or (301) 443-6597. You may, therefore, market the device, subject to the general controls provisions of the Federal Food, Drug, and Cosmetic Act (Act) and the following limitations:
- The Dafilon® Nonabsorbable Polyamide Surgical Suture is indicated for use in 1. general soft tissue approximation and/or ligation, including use in cardiovascular, ophthalmic and neurological procedures.
-
- This device may not be manufactured from any long chain aliphatic polymers other than nylon 6 and/or nylon 6,6. In addition, you must maintain documentation at your premises regarding vendor certification for raw or semiprocessed source material, all manufacturing and quality control release procedures, and validation of sterilization procedures used in the manufacture of the Dafilon® Nonabsorbable Polyamide Surgical Suture. Any deviation of the source material or processing as described in this 510(k) notification requires submission of a new premarket notification and Food and Drug Administration (FDA) clearance prior to commercial distribution of the modified device.

The sale, distribution and use of this device are restricted to prescription use in accordance with 21 CFR 801.109.
The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practices, labeling, and prohibition against misbranding and adulteration.
Existing major regulations affecting your device can be found in the Code of Federal Regulations (CFR), Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Good Manufacturing Practices (GMP) for Medical Devices: General GMP regulation (21 CFR Part 820) and that, through periodic GMP inspections, The Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control Provisions, or other Federal laws or regulations.
This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits vour device to proceed to the market.
