No
The device description is purely mechanical and there is no mention of AI or ML in the summary.

Yes
The device is described as a stainless steel bar intended for use in surgical procedures to repair Pectus Excavation and other sternal deformities, which are conditions requiring medical treatment or correction, making the device therapeutic.

No
The description explicitly states the device is intended for use in surgical procedures to repair sternal deformities, indicating a therapeutic rather than diagnostic purpose.

No

The device description clearly states it is a "stainless steel bar," which is a physical hardware component, not software.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is for surgical procedures to repair sternal deformities. This is a surgical implant used in vivo (within the body).
  • Device Description: The device is a physical bar implanted during surgery.
  • IVD Definition: In Vitro Diagnostics are devices used to examine specimens (like blood, urine, or tissue) outside the body to provide information for diagnosis, monitoring, or screening.

This device clearly falls under the category of a surgical implant or device used directly on the patient during a procedure, not for testing samples in a lab.

§ 888.3030 Single/multiple component metallic bone fixation appliances and accessories.

(a)
Identification. Single/multiple component metallic bone fixation appliances and accessories are devices intended to be implanted consisting of one or more metallic components and their metallic fasteners. The devices contain a plate, a nail/plate combination, or a blade/plate combination that are made of alloys, such as cobalt-chromium-molybdenum, stainless steel, and titanium, that are intended to be held in position with fasteners, such as screws and nails, or bolts, nuts, and washers. These devices are used for fixation of fractures of the proximal or distal end of long bones, such as intracapsular, intertrochanteric, intercervical, supracondylar, or condylar fractures of the femur; for fusion of a joint; or for surgical procedures that involve cutting a bone. The devices may be implanted or attached through the skin so that a pulling force (traction) may be applied to the skeletal system.(b)
Classification. Class II.
