The description focuses on patient-specific mechanical guides based on pre-surgical imaging and surgeon-chosen trajectories, with no mention of AI or ML for image analysis, trajectory planning, or any other function.
No
This device is a surgical guide designed to assist in the accurate placement of screws during spinal fixation procedures, rather than directly treating a disease or condition itself.
No
Explanation: The device is described as a "Cervical Navigation Guide system" intended to provide mechanical guidance for the preparation and drilling of pilot holes for screw placement during posterior spinal fixation procedures. Its purpose is surgical guidance and assistance, not the diagnosis of a disease or condition. The pre-operative CT/CTA scan for determining adequate bone dimensions is a diagnostic step performed separately, with the device utilizing that diagnostic information for surgical planning.
No
The device description explicitly states it consists of "single-use components" including "Patient-Specific Cervical Guides" and "Patient-Specific Bone Models," which are physical components, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The FIREFLY® Cervical Navigation Guide system is a surgical guidance system. It is a mechanical tool used during surgery to assist the surgeon in placing screws in the spine. It does not analyze biological samples or provide diagnostic information about a patient's health status.
- Intended Use: The intended use clearly states it provides "mechanical guidance for the preparation and drilling of pilot holes for the placement of posterior cervical spine... screws". This is a surgical procedure, not a diagnostic test.
- Device Description: The description reinforces that it is a "surgical instrument" and "mechanical guidance" system.
Therefore, the FIREFLY® Cervical Navigation Guide system falls under the category of a surgical device or medical device, not an In Vitro Diagnostic.

Intended Use / Indications for Use
The FIREFLY® Cervical Navigation Guide system is intended to provide mechanical guidance for the preparation and drilling of pilot holes for the placement of posterior cervical spine (C1-C7) and the upper thoracic spine (T1-T3). Pilot holes are created using the FIREFLY® Cervical Navigation Guide in the pedicles (C2-T3), Pars (C2), or lateral masses (C1) during open, posterior spinal fixation procedures, on skeletally mature patients, that are intended for fusion. The patient's pedicles, pars, or lateral masses must be dimensionally adequate to safely accommodate a posterior cervical screw, as determined on a preoperative CT/CTA scan.
The FIREFLY® Cervical Navigation Guide system is compatible with FDA cleared, legally marketed, posterior cervical screw systems (and their respective components) that are specified in the precautions. Pedicle sounding probes (a.k.a. feeler/ball-tip probes) may be used to confirm each pedicle's integrity. Only qualified compatible OEM posterior cervical screw system taps may be used to visually guide the tapping of pilot holes. All other posterior cervical screw system components and accessories (including non-visually guided taps) are to be used, after removal of the FIREFLY @ Cervical Navigation Guide, as directed by the posterior cervical screw system's instructions for use.
The FIREFLY® Cervical Navigation Guide system is only compatible with consoles systems (attachments and burs) listed in the precautions.
This system (guide, bone model, drill bit, and depth stop) are intended for single use only.

Device Description
The FIREFLY® Cervical Navigation Guide is intended to assist in the accurate placement of posterior cervical screws. It consists of single-use components designed for treatment of a specific patient.
The FIREFLY® Cervical Navigation Guide uses Patient-Specific Cervical Guides that fit on the patient's anatomy to guide surgical instruments in line with trajectories chosen presurgically, by the surgeon, based on the patient's CT/CTA imaging data. Navigation guides are intended to guide instruments to create pilot holes in the pedicles (C2-T3), Pars (C2), or lateral masses (C1) for placing screws following the Approved Patient-Specific Surgical Plan.
Patient-Specific Bone Models are also provided.

§ 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.
