Intended Use
AutoStrut G2 is indicated for the following treatments in adults, and in both children (3-12) and adolescents (12-21) in which growth plates have fused and will not be crossed with hardware: - fracture fixation (open and closed) - pseudoarthrosis of long bones - limb lengthening (epiphyseal or metaphyseal distraction) - joint arthrodesis - infected fractures or nonunions - correction of bony or soft tissue deformities ● - correction of segmental defects. ●
Device Description
The AutoStrut G2 is comprised of control system, software, and six length-adjustable struts powered by a motor. The devices are used in conjunction with the DePuy Synthes MAXFRAME multi axial correction system (K161417), including all its parts and software, except that the MAXFRAME struts are substituted with the AutoStrut G2 motorized struts. The MAXFRAME was cleared with software that generates a treatment plan for the patient, detailing how much each strut should be extended after a given amount of time. The output of this software is downloaded to the AutoStrut G2 control box which will then automatically extend the motorized struts the predetermined amount at the prespecified times. The AutoStrut G2 struts are provided in three (3) sizes, Large, Medium and Small corresponding to the MAXFRAM and should be steam sterilized by the user prior to use.
More Information

No
The device description explicitly states that the software generates a "treatment plan" with "predetermined amount[s]" and "prespecified times," which are then automatically executed by the motorized struts. This indicates a rule-based or pre-programmed system, not one that learns or adapts using AI/ML. The "Mentions AI, DNN, or ML" section also states "Not Found".

Yes

The device is indicated for various medical treatments, including fracture fixation, limb lengthening, and correction of deformities, which are therapeutic medical interventions.

No

This device is designed for therapeutic purposes, such as fracture fixation, limb lengthening, and deformity correction, rather than for diagnosing medical conditions. It carries out a predetermined treatment plan generated by separate software.

No

The device description explicitly states that the AutoStrut G2 is comprised of a control system, software, and six length-adjustable struts powered by a motor, indicating it includes hardware components.

Based on the provided information, the AutoStrut G2 is not an IVD (In Vitro Diagnostic) device.

Here's why:

  • IVD Definition: In vitro diagnostic devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
  • AutoStrut G2 Function: The AutoStrut G2 is a mechanical device used for external fixation and correction of bone deformities and fractures. It directly interacts with the patient's skeletal system to apply forces and adjust bone position.
  • Intended Use: The intended uses listed (fracture fixation, limb lengthening, joint arthrodesis, etc.) are all surgical or orthopedic procedures performed directly on the patient's body.
  • Device Description: The description details a mechanical system with struts, motors, and software for controlling the movement of these struts. There is no mention of analyzing biological specimens.

Therefore, the AutoStrut G2 falls under the category of a surgical or orthopedic device, not an in vitro diagnostic device.

§ 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.

Technological Characteristics

The AutoStrut G2 is comprised of control system, software, and six length-adjustable struts powered by a motor. The devices are used in conjunction with the DePuy Synthes MAXFRAME multi axial correction system (K161417), including all its parts and software, except that the MAXFRAME struts are substituted with the AutoStrut G2 motorized struts.

The MAXFRAME was cleared with software that generates a treatment plan for the patient, detailing how much each strut should be extended after a given amount of time. The output of this software is downloaded to the AutoStrut G2 control box which will then automatically extend the motorized struts the predetermined amount at the prespecified times. The AutoStrut G2 struts are provided in three (3) sizes, Large, Medium and Small corresponding to the MAXFRAM and should be steam sterilized by the user prior to use.

Performance Data

· Static compression, static torsion, static cantilever bending, and dynamic compression/tension testing per ASTM F1541

  • · Electrical safety testing per IEC 60601-1 and IEC 60601-1-11
  • · EMC testing per IEC 60601-1-2
  • Software characterization and validation
  • · Sterilization validation per ISO 17665-1, ISO 17665-2, ISO 11737-1 and ISO 11737-2
  • · Cytotoxicity testing per ISO 10993-5
  • Speed and accuracy evaluation
  • Reliability, force and accuracy test
  • Corrosion Test

Substantial Equivalence

AutoStrut G2 is substantially equivalent to OrthoSpin's AutoStrut (K191241). AutoStrut G2 has the exact same indications as the AutoStrut (K191241). Furthermore, it has the same principles of operation and similar technological characteristics as the previously cleared predicate AutoStrut. The primary differences between AutoStrut G2 and AutoStrut are: the motors are assembled separately from the telescopic rods, control box modifications, addition of short strut length to existing medium and long lengths, and software modification to enable more increments per day of rod expansion. In addition, the sterilization method was changed from EtO to steam sterilization by the end user.

These minor differences in the technological characteristics compared to the predicate do not raise different questions of safety or efficacy. Bench testing demonstrates that the AutoStrut G2 is as safe and effective as its predicate device.

Conclusions

The AutoStrut G2 is substantially equivalent to its predicate.
