Intended Use

The Asnis III Cannulated Screw System intended for fracture fixation of small and long bones and of the pelvis. The system is not intended for spinal use.

Device Description

This Special 510(k) submission is intended to address design modifications to the Asnis III Cannulated Screw System. Additional lengths have been added to the 8.0 mm diameter screws. The core thread diameter of the 6.5 mm diameter screws has been modified. The material, intended use, packaging and sterilization of the subject devices are identical to those of predicate devices.

AI/ML Overview

The provided text describes a Special 510(k) submission for modifications to the Asnis III Cannulated Screw System. This type of submission is for device modifications where "Mechanical testing and analysis demonstrates comparable properties of the subject to the predicate device." It does not contain information about an AI-powered medical device or studies related to AI performance.

Therefore, I cannot provide details on the specific points requested (acceptance criteria, device performance, sample sizes, expert qualifications, adjudication, MRMC studies, standalone performance, ground truth types, training set sizes, or ground truth establishment for a training set) because the provided document is about a mechanical screw system modification, not an AI/software device that would typically involve such studies.

The document explicitly states:

  • "This Special 510(k) submission is intended to address design modifications to the Asnis III Cannulated Screw System."
  • "Additional lengths have been added to the 8.0 mm diameter screws. The core thread diameter of the 6.5 mm diameter screws has been modified."
  • "Mechanical testing and analysis demonstrates comparable properties of the subject to the predicate device."

This indicates that the modifications are purely mechanical, and the "study" demonstrating performance is mechanical testing and analysis, which confirms comparability to the predicate device, rather than clinical trials or AI performance evaluations.

Dear Ms. Ariemma:

We have reviewed your Section 510(k) premarket 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 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.

§ 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.
