Intended Use
The IFS Fixation Scaffold is indicated for small bone fixation, reconstruction and fusion such as inter-digital fusion of fingers and toes.
Device Description
The IFS is a hollow fenestrated cylinder fabricated from nitinol with a section that increases the implants diameter to lock into the medullary compartment of bone while shortening its length. The nitinol's transition temperatures are set so that the material is in the austenitic state when released at room temperature. Features on the cylinder's surface, such as bulges and prongs, lock into bone. The IFS is pre-loaded onto an insertion instrument and held elongated in position by a lock plate. During insertion, the IFS is released by turning a knob on its instrument while the lock plate both releases the IFS and limits the depth of implant insertion. The IFS implants range in diameter from 2.5 to 4.5 mm and up to 9.3 mm when expanded and range in length from 21 to 27 mm depending on size and extent of contraction.
More Information

No
The summary describes a mechanical device made of nitinol for bone fixation and does not mention any software, algorithms, or data processing that would indicate the use of AI/ML.

Yes
The device is indicated for "small bone fixation, reconstruction and fusion," which are therapeutic interventions.

No

The device is described as an implantable scaffold for small bone fixation, reconstruction, and fusion, which is a therapeutic rather than a diagnostic function.

No

The device description clearly details a physical implant made of nitinol and an insertion instrument, indicating it is a hardware medical device, not software-only.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is for "small bone fixation, reconstruction and fusion such as inter-digital fusion of fingers and toes." This describes a surgical implant used directly within the body to provide structural support and facilitate healing.
  • Device Description: The description details a physical implant made of nitinol, designed to be inserted into bone. It describes its mechanical properties and how it is deployed.
  • Lack of IVD Characteristics: An IVD device is used in vitro (outside the body) to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. The description of the IFS Fixation Scaffold does not involve any of these activities.

The device is clearly a surgical implant, not a diagnostic tool used with biological samples.

Summary of Performance Studies

Corrosion susceptibility, implant contraction and expansion forces, ultimate strength, amount of shape change and bone fixation strength was measured and compared between the IFS and three predicate devices.
Corrosion testing per ASTM F2129 "Standard Test Method for Conducting Cyclic Potentiodynamic Polarization Measurements to Determine the Corrosion Susceptibility of Small Implant Devices" was performed. The corrosion behavior of the IFS was equivalent or better than the predicate device to which it was compared and presented high corrosion breakdown potentials for all IFS devices tested.
IFS contraction and expansion forces, ultimate strength and bone fixation strength were measured for the IFS and predicate devices. Contraction tests showed that the IFS contraction force causing bone segments to be put into compression was equivalent to or less than the 9x9 mm and 11x10 mm bone staple implants of K123363 and the expansion force causing retention in the medullary canal was equivalent or superior to the K133520 predicate device. Ultimate strength in bending was measured for the IFS. K133520 and K863734 and the IFS was found equivalent or superior in strength to the predicate devices tested. Bone fixation strength was measured for the IFS, K 133520 and K863734 and the IFS was found equivalent or superior to the predicate device.

Appendix I: 510(k) Summary of Safety and Effectiveness

510(k) Summary As required by 21 CFR 807.92: Name of Sponsor: Metric Medical Devices, Inc., 846 Silver Springs, Helotes, TX, 78023 Contact: W. Casey Fox, Ph.D., P.E., President 12/3/2015 Date Prepared: Proprietary Name: IFS Fixation Scaffold System Classification Name: Pin, Fixation, Bone Device classification: Class II per 21 CFR 888.3040 Product Device Code: HTY

Substantial Equivalence: The IFS is substantially equivalent to legally marketed intramedullary implants (K133520), k-wires (K863734) and bone staple (K123363) in indications for use, material, design and function. Any minor differences between these devices or their performance do not raise any questions of safety and effectiveness.

The IFS Fixation Scaffold is indicated for small bone fixation, Indications for use: reconstruction and fusion such as inter-digital fusion of fingers and toes.

Performance Data: Corrosion susceptibility, implant contraction and expansion forces, ultimate strength, amount of shape change and bone fixation strength was measured and compared between the IFS and three predicate devices.

Corrosion testing per ASTM F2129 "Standard Test Method for Conducting Cyclic Potentiodynamic Polarization Measurements to Determine the Corrosion Susceptibility of Small Implant Devices" was performed. The corrosion behavior of the IFS was equivalent or better than the predicate device to which it was compared and presented high corrosion breakdown potentials for all IFS devices tested.

IFS contraction and expansion forces, ultimate strength and bone fixation strength were measured for the IFS and predicate devices. Contraction tests showed that the IFS contraction force causing bone segments to be put into compression was equivalent to or less than the 9x9 mm and 11x10 mm bone staple implants of K123363 and the expansion force causing retention in the medullary canal was equivalent or superior to the K133520 predicate device. Ultimate strength in bending was measured for the IFS. K133520 and K863734 and the IFS was found equivalent or superior in strength to the predicate devices tested. Bone fixation strength was measured for the IFS, K 133520 and K863734 and the IFS was found equivalent or superior to the predicate device.

Device Description: The IFS is a hollow fenestrated cylinder fabricated from nitinol with a section that increases the implants diameter to lock into the medullary compartment of bone while shortening its length. The nitinol's transition temperatures are set so that the material is in the austenitic state when released at room temperature. Features on the cylinder's surface, such as bulges and prongs, lock into bone.

The IFS is pre-loaded onto an insertion instrument and held elongated in position by a lock plate. During insertion, the IFS is released by turning a knob on its instrument while the lock plate both releases the IFS and limits the depth of implant insertion.

The IFS implants range in diameter from 2.5 to 4.5 mm and up to 9.3 mm when expanded and range in length from 21 to 27 mm depending on size and extent of contraction.

Comparison of Technical Characteristics with the Predicate Device:

The IFS and predicates K123363 and K133520 are fabricated from nitinol. The IFS and K123363 change shape at room temperature and K133420 changes at body temperature. The IFS and predicate K123363 have essentially the same manufacturing thermal history and surface treatment. The K863734 predicate is fabricated from stainless steel.

The IFS and K123363 both change shape to pull bone together. The IFS shortens its cylindrical length and the K123363 brings its legs together and shortens its bridge to pull bone segments together and apply fixation forces to bone during healing. The fixation force of the IFS is in the same range as a small K123363 implant.

The IFS and K133520 both have sections that expand to lock into the medullary canal of bone. Features on the surface of these devices include barbs or prongs for locking into bone. The expansion force of the IFS is within the range of expansion forces of the predicate K133520.

The IFS and predicate K123363 and K133520 implants are held with an instrument during insertion. The IFS and K123363 instruments are fabricated from the same material. The instruments hold these implants from changing shape. When released from the instrument the shape changing features of the implants are enabled and the bone locking features engage bone. The IFS and K133520 instruments also act as a depth stop.

The K863734 predicate device is implanted with a drill motor, locks due to surface friction and interference, is round in cross section, solid, and has a trocar tip for cutting bone.

The IFS, K133520, K123363 and K863734 are small devices and similar in size: the IFS is 2.5 to 4.5 mm in diameter and up to 9.3 mm when expanded and its length ranges from 21 to 27 mm; the K 133520 device ranges in width from 4 mm to 7 mm when expanded and its length ranges12 to 25 mm; the K123363 device ranges in bridge and leg length from 9 mm to 20 mm; and the K863734 ranges in diameters of 1 mm to 2 mm and lengths exceeding several inches.
