Yes
The device is used to repair long bone fractures, reattach the greater trochanter, and for sternotomy closure, which are therapeutic interventions.
No.
The device description and intended use indicate that the Metagen ActiveLock™ Wire Cerclage System is used for the repair and stabilization of bone fractures and in total joint reconstruction, which are therapeutic interventions rather than diagnostic procedures.
No
The device description explicitly details physical components made of CoCr alloy wire and a Clamp device, 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 clearly describes a device used for the mechanical repair and stabilization of bone fractures and surgical procedures. This is a therapeutic and structural function, not a diagnostic one.
- Device Description: The description details a wire and clamp system designed to physically secure bone segments. This aligns with a surgical implant or device, not a diagnostic test.
- Lack of Diagnostic Elements: There is no mention of analyzing biological samples (blood, tissue, etc.), detecting biomarkers, or providing information for diagnosis.
- Performance Studies: The performance studies focus on mechanical properties (tensile strength), which are relevant to the structural integrity of a surgical device, not the accuracy of a diagnostic test.
In Vitro Diagnostics are devices used to examine specimens from the human body to provide information for the diagnosis, prevention, or treatment of a disease or condition. The Metagen ActiveLock™ Wire Cerclage System does not fit this definition.

DEVICE DESCRIPTION
Design Characteristics
The Metagen ActiveLock™ Wire Cerclage System is used in the management of orthopedic trauma and total joint reconstruction to secure and stabilize segments of bone. There are two versions of the device disclosed in this submission. The fundamental components of each device are a straight, annealed CoCr alloy wire and a novel Clamp device to secure the wire is 16.5 gage (.048 inch) fully annealed CoCr alloy. (ASTM F-799). A Clamp is provided to secure the wire after tensioning. The Clamp is offered in a "Single" configuration, which secures opposing ends of a single wire, and a "Double" configuration, which secures the free ends of two adjacent wires.
General Operative Technique
The system is clinically applied to fractured bone segments in the same manner as currently marketed wires or cables. The Clamp is placed in the applicator instrument and the wire is fed through the elongated hole all the way to the stop on the wire. The opposite end of the wire is passed around the bone segments with the aid of a wire passer instrument. The wire is then threaded through the adjacent elongated hole in the Clamp and secured in the tensioning element of the applicator. Tensioning can occur only when the Clamp is in the elongated position. When adequate fracture reduction and alignment are obtained, the Clamp is released, securing the wire in place. Typically, several wire assemblies are used to stabilize a single fracture according to accepted surgical practice.

Material Composition
The wire of the Metagen ActiveLock™ Wire Cerclage System is made of CoCr alloy, which is generally available in a composition conforming to ASTM F-799, shown in Exhibit III. This material is commonly used as external fixation pins, cerclage wire for sternotomy closure and other cerclage applications where very high strength is required. The material is supplied in the fully annealed, malleable condition to optimize handling characteristics.
The Clamp is manufactured from NiTi alloy (Nitinol). Nitinol is an alloy consisting of nearly equal atomic percentages of nickel and titanium. The name is derived from its major elements (Ni, Ti) and the fact that it was originally developed at the US Naval Ordinance Laboratory (NOL). It is one of several types of alloy commonly referred to as a shape memory alloy (SMA). SMAs are unique in that they exhibit dramatically different properties than do conventional alloys or metals.
One unique property is the shape memory effect in which an SMA can be plastically deformed into a desired shape then restored to its original shape with the application of heat. Another unique property is the superelastic effect in which an SMA can be mechanically deformed to a large strain (i.e. 8%), returning to its original shape upon removal of the deforming force. Although the composition of the SMA is similar for both effects previously mentioned, the temperature ranges in which the effects occur vary. The Metagen ActiveLock™ Wire Cerclage System uses the superelastic effect to provide the Clamping force needed to securely lock the wire in place. The temperature sensitive, shape-memory property of the material is not utilized.
EQUIVALENCE TO MARKETED PRODUCT
The Metagen ActiveLock™ Wire Cerclage System is substantially equivalent in indications and design principles to the following predicate or pre-amendment devices:
- Metagen ActiveLock™ Cerclage System (K972327) featuring a bone Band device
- . Monofilament wire from manufacturers such as Ethicon and Zimmer
- DePuy Control Cable System .
- Howmedica Dall-Miles Stainless Steel/CoCr Cable .
Intended Use
The indications for use for the Metagen ActiveLock™ Wire Cerclage System and the predicate devices are the same. All of the cable systems are intended for repair of long bone fractures due to trauma or reconstruction, reattachment of the greater trochanter in total hip arthroplasty, or other procedures involving trochanteric osteotomy. The monofiliament wire and most cable systems are indicated for sternotomy closure and segmental sublaminar or intrafacet wiring of the spinal column.

510(k) Summary
Design and Materials
The design and functional characteristics of the Metagen ActiveLock™ Wire Cerclage System are fundamentally the same as the Metagen ActiveLock™ Cerclage Band system. Each system features a novel locking Clamp to secure the cerclage device. Each uses a manual tightening instrument to achieve reduction of a fracture and consolidation of bony fragments. The band of the Metagen ActiveLock™ Cerclage System is made of titanium alloy or Nitinol, while the wire of the Metagen ActiveLock™ Wire Cerclage System is made from CoCr alloy.
The Metagen ActiveLock™ Wire Cerclage System is also comparable to pre-amendment stainless steel suture wire (16 gage). Each device can be used to reduce and a fracture by applying tension, then is fixed in place. In general, monofilament wire is secured by twisting the wire on itself, whereas the subject device is secured by a novel Clamping method.
The subject device is also equivalent to cerclage cable systems, including the DePuy Control Cable System (K934557) and Howmedica Dall-Miles Stainless Steel Cable (K844068, K900926, K961569). Clamping methods for the predicate and subject devices are similar. The predicate devices use a crimp. swage or sleeve in order to maintain tension on the cable after placement and tensioning. Once the cable has been secured by a crimp it can only be removed by cutting. The subject device can be easily removed , re-tensioned and secured without compromising its strength.
Mechanical Testing
Mechanical properties of the subject device were evaluated and compared to 16 gage monofilament wire. The test methods used were identical to those used in K972327 (ActiveLock™ Cerclage Band). The data demonstrate that the Metagen wire/Clamp design provides tensile strength equal to or greater than that of clinically accepted 16 gage stainless steel wire.
