The device description clearly outlines a system of physical instruments (Cannulated Awl Assembly, Implantable Pin Handle Assembly, Exchange Guide and Bend Tube, Implantable Pin) used for surgical fixation of bone fractures. There is no mention of software components.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information about a person's health. This testing is performed outside of the body (in vitro).
- Device Function: The Metacarpal Fixation System is a surgical device used to physically fix fractures in metacarpal bones. It is implanted into the body to provide structural support during healing.
- Intended Use: The intended use is for the "fixation of transverse or short oblique fractures," which is a surgical procedure, not a diagnostic test performed on a specimen.
- Device Description: The description details surgical tools and an implantable pin, not equipment for analyzing biological samples.
Therefore, the Metacarpal Fixation System is a surgical device, not an In Vitro Diagnostic device.

Device Description
The MFS is a sterile, single use, disposable device that is delivered non-toxic. The MFS consists of the Cannulated Awl Assembly, the Implantable Pin Handle Assembly, and Exchange Guide and Bend Tube. A typical MFS is shown in Figure 1, MFS Assembled Implantable Pin Handle and Cannulated Awl Assemblies. Figure 2, Implantable pin and Awl Assemblies shows the assemblies separately.
Prior to use the implantable pin assembly is nested in the cannulated awl assembly. The cannulated awl assembly has a trocar point. The implantable pin has a blunt point that is positioned just behind the trocar point of the cannulated awl. The sharp point of the cannulated awl assembly is passed through a small incision. A hole is drilled into the metacarpal bone by twisting the assembled handles back and forth. After gaining access to the intramedullary space, the cannulated awl handle is held stationary while the implantable pin is then advanced distally from the base of the metacarpal bone. See Figure 3, MFS Partially Deployed.
The awl handle is then withdrawn and removed for advancement of the implantable pin. The implantable pin is then cut adjacent to the pin handle. Using the bending tube end of the exchange guide and bend tube pictured in Figure 4, Exchange Guide and Bend Tube, the implantable pin is bent to 90° with the apex of the implantable pin insertion site. The pin is trimmed so that the end is below the skin. The small piece remaining will facilitate removal of the implantable pin subsequent to healing. The implantable pin will remain implanted for approximately six weeks. Upon healing of the fracture, the implantable pin is percutaneously removed.
In the event that it is desired to reform the implantable pin or implant a smaller pin, this may be accomplished without loosing access to the medullary canal. The exchange guide is advanced along the implantable pin into the medullar space. Once the medullar space is accessed, the pin is removed. Another pin may be placed into the medulla by inserting it into the groove of the exchange guide. After the pin has been inserted into the medullar space, remove the exchange guide.

- The Metacarpal Fixation System has a different drill geometry than the predicate because it is designed to be compliant with the trocar point requirements of ISO 5838-3, Implants for Surgery - Skeletal Pins and Wires - Part 3: Kirschner Skeletal Wires.
-
Working length of the Metacarpal Fixation System has a shorter working than the predicate device because it is not a multi-purpose device. It needs only to accommodate the length of metacarpal bones.
-
Placement of implantable pins in the metacarpal bone does not require the use of a powered drill. Because the Metacarpal Fixation System is restricted to metacarpal use it is not designed for use with a powered drill.
