Intended Use
The Smith & Nephew Interference Screws are used for fixation of ligaments and tendons in patients requiring ligament or tendon repair.
Device Description
The Smith & Nephew Titanium Interference Screws are available in various geometric configurations. The Smith & Nephew Titanium Interference Screws arc made with titanium alloy material. The range in diameters and lengths, combined with the variations in geometric configurations, provide the surgeon with a wide variety of sizes/configurations to choose from. Screws are available in both cannulated and non-cannulated styles. The screws may be purchased either sterile or non-sterile, to be sterilized by the end user.
More Information

Not Found

No
The 510(k) summary describes a mechanical device (interference screws) and its performance based on physical properties (insertion torque, pullout force). There is no mention of AI, ML, image processing, or data analysis that would suggest the use of such technologies.

Yes.
This device is used for the fixation of ligaments and tendons in patients requiring repair, which directly addresses a medical condition or injury.

No
The device is described as an interference screw used for fixation of ligaments and tendons, which suggests a therapeutic or surgical tool, not one used for diagnosis. There is no mention of it being used to identify or predict medical conditions.

No

The device description clearly states it is a physical titanium screw, which is a hardware component.

Based on the provided information, the Smith & Nephew Interference Screws are not an IVD (In Vitro Diagnostic) device.

Here's why:

  • Intended Use: The intended use is for the fixation of ligaments and tendons in patients requiring repair. This is a surgical procedure performed directly on the patient's body.
  • Device Description: The device is a physical screw made of titanium alloy, designed to be implanted.
  • Lack of IVD Characteristics: IVD devices are used to examine specimens (like blood, urine, or tissue) outside of the body to provide information about a patient's health. The description of the Smith & Nephew Interference Screws does not involve any such testing of specimens.

Therefore, the Smith & Nephew Interference Screws are a surgical implant, not an in vitro diagnostic device.

§ 888.3040 Smooth or threaded metallic bone fixation fastener.

(a)
Identification. A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.(b)
Classification. Class II.

Dear Ms. Lima:

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.
