No
The summary describes a patient-specific surgical guide based on pre-surgical CT data and a surgeon's plan. There is no mention of AI or ML being used for image analysis, trajectory planning, or any other function of the device. The device appears to be a passive mechanical guide.
No
The device is a surgical navigation guide, providing assistance in the accurate placement of pedicle screws by guiding surgical instruments. It does not directly treat or prevent a disease and is not itself a therapeutic intervention.
No
The device is described as a surgical navigation guide intended to assist in the accurate placement of pedicle screws, guiding instruments to create pilot holes. It uses pre-surgical CT imaging data to plan the trajectories but does not diagnose conditions or diseases.
No
The device description explicitly states it consists of "single-use components designed for treatment of a specific patient" and "Patient-Specific Guides that fit on the patient's anatomy to guide surgical instruments." This indicates the device includes physical, patient-specific hardware components, not just software.
Based on the provided information, 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, or tissue) to provide information for diagnosis, monitoring, or screening.
- Device Function: The FIREFLY® Midline Navigation Guide is a surgical guide used during a surgical procedure to assist in the placement of pedicle screws. It interacts directly with the patient's anatomy to guide instruments.
- Intended Use: The intended use clearly describes a surgical procedure for spinal fixation, not the analysis of biological specimens.
- Device Description: The description focuses on patient-specific guides that fit on the patient's anatomy and guide surgical instruments.
- Input Data: While it uses CT imaging data for planning, this data is used to create a physical guide for surgery, not for in vitro analysis of a specimen.
The device is a surgical navigation guide, which falls under a different regulatory category than IVDs.

- o Compatible pedicle screw spinal system instruments may be used with the FIREFLY® Midline Screw Navigation Guide
- Pedicle sounding probes (a.k.a. feeler/ball-tip probes) may be used with the FIREFLY® o Midline Navigation Guide to confirm pedicle integrity
- All other pedicle screw spinal system components and accessories (including non o quided taps) are to be used, after removal of the FIREFLY® Midline Navigation Guide, as directed by the pedicle screw spinal system's instructions for use
This device is intended for single use only.

Device Description
The FIREFLY® Midline Navigation Guide is intended to assist in the accurate placement of pedicle screws. It consists of single-use components designed for treatment of a specific patient.
The FIREFLY® Midline Navigation Guide uses Patient-Specific 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 imaging data. Navigation Guides are intended to guide instruments to create pilot holes in the pedicles for placing pedicle screws following the Approved Surgical Plan.
Patient-Specific Bone Models are also provided.
The primary purpose of the 510(k) is to receive clearance from the Food and Druq Administration ("FDA" or "the Agency") regarding the above requests.
The FIREFLY® Midline Navigation Guide design is the originally cleared FIREFLY® Pedicle Screw Navigation Guide in K143222 and K162419.

§ 888.3070 Thoracolumbosacral pedicle screw system.
(a)
Identification. (1) Rigid pedicle screw systems are comprised of multiple components, made from a variety of materials that allow the surgeon to build an implant system to fit the patient's anatomical and physiological requirements. Such a spinal implant assembly consists of a combination of screws, longitudinal members (e.g., plates, rods including dual diameter rods, plate/rod combinations), transverse or cross connectors, and interconnection mechanisms (e.g., rod-to-rod connectors, offset connectors).(2) Semi-rigid systems are defined as systems that contain one or more of the following features (including but not limited to): Non-uniform longitudinal elements, or features that allow more motion or flexibility compared to rigid systems.
(b)
Classification. (1) Class II (special controls), when intended to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion in the treatment of the following acute and chronic instabilities or deformities of the thoracic, lumbar, and sacral spine: severe spondylolisthesis (grades 3 and 4) of the L5-S1 vertebra; degenerative spondylolisthesis with objective evidence of neurologic impairment; fracture; dislocation; scoliosis; kyphosis; spinal tumor; and failed previous fusion (pseudarthrosis). These pedicle screw spinal systems must comply with the following special controls:(i) Compliance with material standards;
(ii) Compliance with mechanical testing standards;
(iii) Compliance with biocompatibility standards; and
(iv) Labeling that contains these two statements in addition to other appropriate labeling information:
“Warning: The safety and effectiveness of pedicle screw spinal systems have been established only for spinal conditions with significant mechanical instability or deformity requiring fusion with instrumentation. These conditions are significant mechanical instability or deformity of the thoracic, lumbar, and sacral spine secondary to severe spondylolisthesis (grades 3 and 4) of the L5-S1 vertebra, degenerative spondylolisthesis with objective evidence of neurologic impairment, fracture, dislocation, scoliosis, kyphosis, spinal tumor, and failed previous fusion (pseudarthrosis). The safety and effectiveness of these devices for any other conditions are unknown.”
“Precaution: The implantation of pedicle screw spinal systems should be performed only by experienced spinal surgeons with specific training in the use of this pedicle screw spinal system because this is a technically demanding procedure presenting a risk of serious injury to the patient.”
(2) Class II (special controls), when a rigid pedicle screw system is intended to provide immobilization and stabilization of spinal segments in the thoracic, lumbar, and sacral spine as an adjunct to fusion in the treatment of degenerative disc disease and spondylolisthesis other than either severe spondylolisthesis (grades 3 and 4) at L5-S1 or degenerative spondylolisthesis with objective evidence of neurologic impairment. These pedicle screw systems must comply with the following special controls:
(i) The design characteristics of the device, including engineering schematics, must ensure that the geometry and material composition are consistent with the intended use.
(ii) Non-clinical performance testing must demonstrate the mechanical function and durability of the implant.
(iii) Device components must be demonstrated to be biocompatible.
(iv) Validation testing must demonstrate the cleanliness and sterility of, or the ability to clean and sterilize, the device components and device-specific instruments.
(v) Labeling must include the following:
(A) A clear description of the technological features of the device including identification of device materials and the principles of device operation;
(B) Intended use and indications for use, including levels of fixation;
(C) Identification of magnetic resonance (MR) compatibility status;
(D) Cleaning and sterilization instructions for devices and instruments that are provided non-sterile to the end user; and
(E) Detailed instructions of each surgical step, including device removal.
(3) Class II (special controls), when a semi-rigid system is intended to provide immobilization and stabilization of spinal segments in the thoracic, lumbar, and sacral spine as an adjunct to fusion for any indication. In addition to complying with the special controls in paragraphs (b)(2)(i) through (v) of this section, these pedicle screw systems must comply with the following special controls:
(i) Demonstration that clinical performance characteristics of the device support the intended use of the product, including assessment of fusion compared to a clinically acceptable fusion rate.
(ii) Semi-rigid systems marketed prior to the effective date of this reclassification must submit an amendment to their previously cleared premarket notification (510(k)) demonstrating compliance with the special controls in paragraphs (b)(2)(i) through (v) and paragraph (b)(3)(i) of this section.
