The document describes a mechanical spinal implant system and its components. There is no mention of software, algorithms, image processing, or any other technology that would typically incorporate AI/ML. The performance studies are mechanical and biological tests, not algorithmic performance evaluations.
Yes
The device is intended to provide immobilization of spinal segments as an adjunct to fusion for a variety of acute and chronic instabilities, including traumatic fractures, instability, deformity, and degenerative diseases. It is also used to restore the integrity of the spinal column in patients with advanced stage tumors. These uses clearly fall under the definition of therapeutic interventions.
No
The device description indicates it is a posterior occipitocervical-upper thoracic system consisting of plates, rods, hooks, screws, and connectors, all intended for spinal immobilization as an adjunct to fusion. This describes an implantable surgical device, not one used for diagnosis.
No
The device description explicitly states it consists of physical components like plates, rods, hooks, screws, and connectors made of titanium alloy and cobalt chromium. It also details mechanical testing of these physical implants.
Based on the provided information, the INFINITY™ OCT System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use clearly states that the device is for the immobilization of spinal segments as an adjunct to fusion for various spinal instabilities and conditions. This is a therapeutic and structural purpose, not a diagnostic one.
- Device Description: The device is described as a system of plates, rods, hooks, screws, and connectors made from medical grade materials. These are physical implants used in surgery.
- Lack of Diagnostic Function: There is no mention of the device being used to examine specimens from the human body (like blood, tissue, etc.) to provide information for diagnosis, monitoring, or screening.
- Performance Studies: The performance studies focus on mechanical testing and non-pyrogenicity, which are relevant to the structural integrity and safety of an implantable device, not the performance of a diagnostic test.
In summary, the INFINITY™ OCT System is a surgical implant designed to provide structural support and stability to the spine. It does not perform any diagnostic function.
N/A
Intended Use / Indications for Use
The INFINITY™ OCT System is intended to provide immobilization of spinal segments as an adjunct to fusion for the following acute and chronic instabilities of the craniocervical junction, the cervical spine (C1 to C7), and the thoracic spine from T1-T3:
- · Traumatic spinal fractures and/or traumatic dislocations.
- · Instability or deformity.
- · Failed previous fusions (e.g. pseudarthrosis).
- · Tumors involving the cervical spine.
- · Degenerative disease, including intractable radiculopathy, neck and/or arm pain of discogenic origin as confirmed by radiographic studies, and degenerative disease of the facets with instability.
The INFINITY™ OCT System is also intended to restore the integrity of the spinal column even in the absence of fusion for a limited time in patients with advanced stage tumors involving the cervical spine in whom life expectancy is of insufficient duration to permit achievement of fusion.
In order to achieve additional levels of fixation, the INFINITY™ OCT System may be connected to the CD HORIZON® Spinal System and VERTEX Reconstruction System rods with the INFINITY™ OCT System rod connectors. Transition rods with differing diameters may also be used to connect the INFINITY™ OCT System to the CD HORIZON® Spinal System. Refer to the CD HORIZON® Spinal System package insert and VERTEX® Reconstruction System package insert for a list of the indications of use.
Note: The 3.0mm multi axial screw (MAS) requires the use of MAS CROSSLINK® at each level in which the 3.0mm screw is intended to be used.
The lateral offset connectors and MAS extension connectors are intended to be used with 3.5mm and larger diameter multi axial screws. The lateral offset connectors and MAS extension connectors are not intended to be used with 3.0mm screws.
Note: Segmental fixation is recommended for these constructs.

§ 888.3075 Posterior cervical screw system.
(a)
Identification. Posterior cervical screw systems are comprised of multiple, interconnecting components, made from a variety of materials that allow an implant system to be built from the occiput to the upper thoracic spine to fit the patient's anatomical and physiological requirements, as determined by preoperative cross-sectional imaging. Such a spinal assembly consists of a combination of bone anchors via screws (i.e., occipital screws, cervical lateral mass screws, cervical pedicle screws, C2 pars screws, C2 translaminar screws, C2 transarticular screws), longitudinal members (e.g., plates, rods, including dual diameter rods, plate/rod combinations), transverse or cross connectors, interconnection mechanisms (e.g., rod-to-rod connectors, offset connectors), and closure mechanisms (e.g., set screws, nuts). Posterior cervical screw systems are rigidly fixed devices that do not contain dynamic features, including but not limited to: non-uniform longitudinal elements or features that allow more motion or flexibility compared to rigid systems.Posterior cervical screw systems are intended to provide immobilization and stabilization of spinal segments in patients as an adjunct to fusion for acute and chronic instabilities of the cervical spine and/or craniocervical junction and/or cervicothoracic junction such as: (1) Traumatic spinal fractures and/or traumatic dislocations; (2) deformities; (3) instabilities; (4) failed previous fusions (
e.g., pseudarthrosis); (5) tumors; (6) inflammatory disorders; (7) spinal degeneration, including neck and/or arm pain of discogenic origin as confirmed by imaging studies (radiographs, CT, MRI); (8) degeneration of the facets with instability; and (9) reconstruction following decompression to treat radiculopathy and/or myelopathy. These systems are also intended to restore the integrity of the spinal column even in the absence of fusion for a limited time period in patients with advanced stage tumors involving the cervical spine in whom life expectancy is of insufficient duration to permit achievement of fusion.(b)
Classification. Class II (special controls). The special controls for posterior cervical screw systems are:(1) The design characteristics of the device, including engineering schematics, must ensure that the geometry and material composition are consistent with the intended use.
(2) Nonclinical performance testing must demonstrate the mechanical function and durability of the implant.
(3) Device components must be demonstrated to be biocompatible.
(4) Validation testing must demonstrate the cleanliness and sterility of, or the ability to clean and sterilize, the device components and device-specific instruments.
(5) Labeling must include the following:
(i) A clear description of the technological features of the device including identification of device materials and the principles of device operation;
(ii) Intended use and indications for use including levels of fixation;
(iii) Device specific warnings, precautions, and contraindications that include the following statements:
(A) “Precaution: Preoperative planning prior to implantation of posterior cervical screw systems should include review of cross-sectional imaging studies (
e.g., CT and/or MRI) to evaluate the patient's cervical anatomy including the transverse foramen, neurologic structures, and the course of the vertebral arteries. If any findings would compromise the placement of these screws, other surgical methods should be considered. In addition, use of intraoperative imaging should be considered to guide and/or verify device placement, as necessary.”(B) “Precaution: Use of posterior cervical pedicle screw fixation at the C3 through C6 spinal levels requires careful consideration and planning beyond that required for lateral mass screws placed at these spinal levels, given the proximity of the vertebral arteries and neurologic structures in relation to the cervical pedicles at these levels.”
(iv) Identification of magnetic resonance (MR) compatibility status;
(v) Cleaning and sterilization instructions for devices and instruments that are provided non-sterile to the end user, and;
(vi) Detailed instructions of each surgical step, including device removal.
