No
The device description focuses on mechanical components and their function in mandibular distraction. There is no mention of software, algorithms, or data processing that would indicate the use of AI or ML.
Yes
The device is used for mandibular distraction osteogenesis to treat conditions like congenital micrognathia and post-traumatic mandibular deformities, which are therapeutic interventions.
No
The device is described as an "intraoral, subcutaneous distractor" used for "mandibular distraction osteogenesis" to lengthen the mandible or address defects. It is an active medical device that physically alters the patient's anatomy rather than collecting or interpreting diagnostic information.
No
The device description clearly details a physical, implantable medical device made of stainless steel with mechanical components (telescoping bodies, adjustment screws, bone plates, screws). There is no mention of any software component.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health. This testing is done outside the body (in vitro).
- Device Description: The Telescopic Distractor is an implantable surgical device used to physically lengthen the mandible through a process called distraction osteogenesis. It is surgically placed inside the body (intraoral, subcutaneous) and directly interacts with bone tissue.
The device's function and intended use are entirely focused on a surgical procedure within the body, not on analyzing biological samples outside the body.

Intended Use / Indications for Use
The Telescopic Distractor is an intraoral, subcutaneous distractor which is used for mandibular distraction osteogenesis. The device is indicated for use in patients with congenital micrognathia, post-traumatic mandibular deformities, or defects resulting from tumor resection. In conjunction with osteotomy or corticotomy, the Telescopic Distractor may be used for.
- mandibular body lengthening; .
- mandibular ramus lengthening;
- distraction osteogenesis across a mandibular segmental defect in the ramus, body, or symphysis; and
- transport distraction osteogenesis across a mandibular segmental . defect in the ramus, body, or symphysis.
The device may be used in adult, adolescent, or pediatric patients.

Device Description
Innova Corporation requests marketing clearance for the Telescopic Distractor, an intraoral subcutaneous device that permits either unilateral lengthening of the mandible. The device consists of forward and rear telescoping bodies that are held together by a central element.
The subject device is designed with a central element that can be moved in opposing directions by turning an adjustment screw, producing the telescopic action. The telescoping bodies are attached to the inferior border of the mandibular osteotomy with bone plates and screws. The telescopic elements slide freely in the central element. The maximum amount of distraction possible between the two sections is 18 millimeters.
A circular pin and a separate adjustment screw attaches the forward telescoping element to the forward bone plate. The circular pin provides a rigid, interlocking connection because of the snug fit within the opening in the forward telescoping element. The forward bone plate can be moved transversely relative to the telescopic elements by the adjustment screw. The rear telescopic element is similarly connected to the rear bone plate. The forward and rear bone plate elements are secured to the mandible with four bicortical stainless steel bone screws.
Following placement of the distractor, the clinician waits for a period of 5 to 10 days to allow for intraoral healing prior to initiating distraction.
The Innova Telescoping Distractor is made from wrought surgical grade stainless steel. The material conforms to ASTM F 138-97. This material is currently used in a variety of implanted devices such as bone plates and has a demonstrated biocompatibility by its long history of use for implant applications.
The Telescoping Distractor is available in two models; unilateral and bilateral. The devices are operated and applied in an identical manner, except that the unilateral model is intended for distraction osteogenesis of either the right or the left side of the mandible. while the bilateral model is intended to be used for simultaneous distraction osteogenesis of both the right and left sides of the mandible.

1. Intended Use:
Innova Corporation requests clearance to market a Telescopic Distractor, an intraoral device which is intended to permit the lengthening of the mandible. The device is designed to allow either unilateral or bilateral distraction. The Innova Telescopic Distractor can allow for up to 18 mm of distraction. The device is intended for use in adult, adolescent or pediatric patients.

Innova Corporation requests marketing clearance for the Telescopic Distractor, an intraoral subcutaneous device that permits either unilateral lengthening of the mandible. The device consists of forward and rear telescoping bodies that are held together by a central element.

Following placement of the distractor, the clinician waits for a period of 5 to 10 days to allow for intraoral healing prior to initiating distraction.
The Innova Telescoping Distractor is made from wrought surgical grade stainless steel. The material conforms to ASTM F 138-97. This material is currently used in a variety of implanted devices such as bone plates and has a demonstrated biocompatibility by its long history of use for implant applications.

The devices are operated and applied in an identical manner, except that the unilateral model is intended for distraction osteogenesis of either the right or the left side of the mandible. while the bilateral model is intended to be used for simultaneous distraction osteogenesis of both the right and left sides of the mandible.
The device is indicated for the following procedures:
- . mandibular body lengthening
- mandibular ramus lengthening ●
- distraction osteogenesis across a mandibular segmental defect in the ramus, ● body or symphysis
- transport distraction osteogenesis across a mandibular segmental defect in the . ramus, body, or symphysis
The device is indicated for use in adult, adolescent and pediatric patients.
The sponsor claims substantial equivalence to the previously cleared devices intended for use in distraction osteogenesis, such as the Howmedica, Inc. Mandibular Distractor II, cleared

as K960297. The devices share the same intended use and principle of operation. The devices share similar technological characteristics.
The Howmedica Mandibular Bone Distractor II (K960297) was cleared for use in adults and children. The predicate device is intended as both a stabilizer and bone lengthener through distraction of the mandible. The predicate device is supplied non-sterile and is labeled for single use only. The Innova device is also supplied non sterile. Sterilization instructions are included in the draft labeling included as attachment 8 in the document. The labeling clearly statesthat the device is intended for single use only and should therefore not be resterilized for reuse by any method. The product is packaged in Tyvek and is ready for processing in the autoclave.
ANALYSIS:
The subject device, the Innova Telescopic Distractor is substantially Equivalent to previously cleared devices for a similar intended use.
RECOMMENDATIONS:
SUBSTANTIALLY EQUIVALENT
