Intended Use
The Gamma 3 Lag Screw is intended to be used with both the Long Length Dyax Nail and the Trochanteric Dyax Nail. Intended Use for the Long Length Dyax Nail The product is intended to be used in fixation of femoral fractures occurring from the base of the femoral neck extending distally to a point approximately 10 cm proximal to the intracondylar notch. Fracture types include basilar neck, intertrochanteric fractures and femoral shaft fractures. These femoral fractures may occur as a result of trauma, non-union, malunion, pathological fractures, and impending pathological fractures. Intended Use for the Trochanteric Dyax Nail The product is intended for use in stabilizing various types of intertrochanteric fractures of the femur.

No
The 510(k) summary describes a mechanical implant (lag screw) with design modifications to its physical characteristics (thread diameter, radius, cutting flute). There is no mention of software, algorithms, image processing, or any terms related to AI/ML.

Yes
The device, a lag screw, is intended for the fixation and stabilization of femoral fractures, which is a therapeutic purpose.

No
The device is described as a "Lag Screw" intended for fixation and stabilizing of femoral fractures. This indicates a therapeutic or surgical purpose, not a diagnostic one.

No

The device description clearly states it is a "Lag Screw" and describes physical design modifications (thread diameter, radius, cutting flute design), indicating it is a physical implantable device, not software.

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

Here's why:

  • Intended Use: The intended use clearly describes the device as being used for the fixation and stabilization of femoral fractures. This is a surgical procedure performed directly on the patient's body.
  • Device Description: The device is described as a "Lag Screw" used with "Nails," which are implants for bone fixation. This is consistent with a surgical implant, not a device used to examine specimens from the body.
  • Lack of IVD Characteristics: There is no mention of the device being used to test or analyze samples (blood, urine, tissue, etc.) from the human body to provide information about a physiological state, health, disease, or congenital abnormality.

IVD devices are used in vitro (outside the body) to examine specimens. This device is used in vivo (inside the body) for surgical repair.
