Intended Use
The Medline UNITE® REFLEX® Nitinol Staples are intended to provide fixation for fractures of the bones of the hand and foot such as: First metatarsalcuneiform arthrodesis, First metatarsophalangeal arthrodesis, Talo-Navicular Fusion, LisFranc arthrodesis, Akin osteotomy, Scarf and Chevron osteotomies. Staples are intended for single use only.
Device Description
The Medline UNITE® REFLEX® Nitinol Staples are manufactured from nickel titanium alloy (Nitimol). The staples utilize chemical etching and passivation to form a protective oxidation layer on the outer surface. The system includes staples offered in a range of sizes from 8mm x 20mm x 20mm. The Medline UNITE® REFLEX® Nitinol Staples are offered in different bridge lengths and include 2-leg and 4-leg staples. The system also includes reusable instrumentation necessary to implant the staples, e.g. drill guides, drills, locating pins, staple inserter, and tamp.
More Information

No
The device description and performance studies focus on the material properties and mechanical performance of the staples, with no mention of AI or ML.

Yes
The device is a medical staple used for fixating fractures, which directly treats a medical condition.

No

This device is a surgical staple intended for fixation of bone fractures, not for diagnosing medical conditions. Its purpose is to treat, not to diagnose.

No

The device description clearly states it is a physical medical device (nitinol staples) and includes reusable instrumentation for implantation. It is not software-only.

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

Here's why:

  • IVD devices are used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information about a person's health.
  • This device is an implantable surgical staple used to fix bone fractures. It is directly implanted into the body and does not analyze biological specimens.

The description clearly states its intended use is for "fixation for fractures of the bones of the hand and foot" and that it is "manufactured from nickel titanium alloy". This is consistent with a surgical implant, not an in vitro diagnostic device.

Summary of Performance Studies

Engineering analysis was performed to compare the subject staple's bending strength/stiffness and pullout performance per ASTM F564 to the predicate staples (K210482).
Corrosion susceptibility testing was conducted per ASTM F2129 and the FDA guidance document Technical Considerations for Non-Clinical Assessment of Medical Devices Containing Nitinol. Testing was conducted to ensure that the proposed Medline UNITE® REFLEX® Nitinol Staples meet the predefined acceptance criteria. All samples achieved electrostatic breakdown potential in excess of the minimum acceptance criteria, demonstrating acceptable corrosion susceptibility.

§ 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.

K210482. This new 510(k) for the staples includes additional specific indications including: First metatarsalcuneiform arthrodesis, First metatarsophalangeal arthrodesis, Talo-Navicular fusion. These additional more specific indications are fractures, fusions, and osteotomies in the same anatomical locations. Therefore, these indications fall under the original indications for use and do not result in a new intended use.

  • Design features same. Both the new predicate and the subject staples are offered in straight top ● configurations.
  • Leg Lengths different. The predicate and subject devices are both offered in identical leg lengths ● of 8mm. 10mm. 12mm. 15mm. 20mm and 25mm. The subject device is also available in 14mm and 16mm leg lengths that are within the cleared range of lengths of the predicate device.
  • Staple legs different. The predicate staple is available in a 2-leg design. The subject Medline ● UNITE® REFLEX® Nitinol Staple System will also be offered in a 2-leg design, as well as, a 4leg design.
  • Bridge Lengths different. The predicate and subject 2-leg staples are both offered in identical ● lengths of 8mm, 10mm, 12, 15mm, 20mm and 25mm. The subject 2-leg staple is also available in 23mm which is within the cleared range of lengths of the predicate device. The subject 4-leg staples will be offered in slightly longer lengths of 26mm as well. The difference in bridge lengths does not affect safety or effectiveness of the devices.

Summary of Non-Clinical Testing

The subject Medline UNITE® REFLEX® Nitimol Staples do not represent a new worst-case when compared to the previously cleared Medline UNITE® REFLEX® Nitinol Staples (K210482).

An engineering analysis was performed to determine the subject Medline UNITE® REFLEX® Nitinol Staples do not represent a new worst-case when compared to the previously cleared Medline UNITE® REFLEX® Nitinol Staples (K210482) for bending and pullout performance. The results of this analysis demonstrate the subject Medline UNITE® REFLEX® Nitinol Staples are substantially equivalent to the predicate Medline UNITE® REFLEX® Nitinol Staples (K210482).

To determine the worst-case staple for corrosion susceptibility representing the subject Medline UNITE® REFLEX® Nitinol Staple, an additional engineering analysis was conducted. The results of this analysis and subsequent testing demonstrate the subject Medline UNITE® REFLEX® Nitinol Staples are substantially equivalent to the predicted Medline UNITE® REFLEX® Nitinol Staples (K210482).

Performance Testing (Bench)

The following testing was performed to demonstrate substantial equivalence between the proposed Medline UNITE® REFLEX® Nitinol Staples and the predicate Medline UNITE® REFLEX® Nitinol Staples (K210482).

Engineering analysis was performed to compare the subject staple's bending strength/stiffness and pullout performance per ASTM F564 to the predicate staples (K210482).

Corrosion susceptibility testing was conducted per ASTM F2129 and the FDA guidance document Technical Considerations for Non-Clinical Assessment of Medical Devices Containing Nitinol. Testing was conducted to ensure that the proposed Medline UNITE® REFLEX® Nitinol Staples meet the predefined acceptance criteria. All samples achieved electrostatic breakdown potential in excess of the minimum acceptance criteria, demonstrating acceptable corrosion susceptibility.
