Intended Use
The Modus® Modular Distraction Osteogenesis System is a subcutaneous distractor system intended for use in fractures, osteotomies and arthrodeses including: treatment of hemifacial microsomia, mandibular hypoplasia, microglossia, defects of the alveolar ridge, atrophic bone segments in the mandible and maxilla, mandibular symphysis widening, growth disturbances of the ascending corpus/ascending ramus, and LeFort I, and LeFort II/III advancements.
Device Description
The Modus plates are used with the Modus Distraction Cylinders for various applications of the maxillofacial bone structures. The Modus plates are offered in a variety of sizes and are designed to fit the anatomy of the mandible and/or maxilla and allow adjustment of the vector by intra-operative bending if indicated. The Modus Distraction Cylinders are used with the Modus plates and screws for gradual bone distraction osteogenesis and for corrective osteotomies of the mandible and maxilla. The Modus distraction cylinders are available in uni-directional or bi-directional with multiple distraction lengths. Flexible extensions are to be used with distraction cylinders if needed. The extensions allow additional access for distraction of the surgical site. The implant plates and ARS distractors are made of CP titanium Grade 4 and comply with ASTM F 67 standards for unalloyed titanium for surgical implant applications. The MDO distraction cylinders and flexible extensions are made of implant steel that complies with ASTM F 138 or ASTM F 139.
More Information

Not Found

No
The device description focuses on mechanical components (plates, cylinders, screws, extensions) and materials, with no mention of software, algorithms, or data processing that would indicate AI/ML. The "Mentions AI, DNN, or ML" and "Mentions image processing" sections are explicitly marked as "Not Found".

Yes
The device is described as a "subcutaneous distractor system intended for use in fractures, osteotomies and arthrodeses," which are therapeutic interventions. Its primary purpose is to gradually distract bone for corrective purposes, addressing conditions like hemifacial microsomia and mandibular hypoplasia.

No

Explanation: The device description clearly states its purpose is for "gradual bone distraction osteogenesis and for corrective osteotomies," which are surgical treatment procedures, not diagnostic ones.

No

The device description explicitly details physical components made of titanium and steel, such as plates, cylinders, and extensions, which are implanted in the body. This indicates it is a hardware-based medical device, not software-only.

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

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health.
  • Device Description and Intended Use: The Modus® Modular Distraction Osteogenesis System is a surgical implant used to gradually lengthen bone in the maxillofacial region. It is physically implanted into the patient's body and directly interacts with bone tissue.
  • Lack of IVD Characteristics: The description does not mention any testing of biological samples, analysis of bodily fluids, or providing diagnostic information based on laboratory tests.

Therefore, the Modus® Modular Distraction Osteogenesis System is a surgical device, not an In Vitro Diagnostic.
