No
The document describes a mechanical spinal fixation system and does not mention any software, algorithms, or AI/ML capabilities.
Yes
The device is intended to provide "immobilization and stabilization of spinal segments... as an adjunct to fusion" in the treatment of various spinal instabilities or deformities, which is a therapeutic purpose.
No
The device description indicates it is a spinal fixation system, used for immobilization and stabilization of spinal segments, and the "Indications for Use" section lists conditions it treats, not conditions it diagnoses.
No
The device description explicitly details physical implants (screws, rods, crossbars, connectors, locking elements, etc.) and instruments made of titanium and cobalt chrome alloys. It also mentions trays and caddies for storage and sterilization. This clearly indicates a hardware-based medical device, not a software-only one.
No, 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, or tissue) to provide information about a person's health.
- Device Description: The Mariner Pedicle Screw System is a surgical implant and instrumentation system used to stabilize the spine. It is physically implanted into the body.
- Intended Use: The intended use is to provide immobilization and stabilization of spinal segments as an adjunct to fusion. This is a surgical procedure, not a diagnostic test performed on a sample.
The information provided clearly describes a surgical device used for structural support and stabilization within the body, which is the opposite of an in vitro diagnostic device.

Device Description
The Mariner Pedicle Screw System is a non-cervical spinal fixation device and instrumentation system intended for use as a posterior pedicle screw fixation system, a posterior non-pedicle fixation system, and/or an anterolateral fixation system. The system consists of single-use implants including fixed, polyaxial, cephalad/caudal restricted-motion, and medial/lateral restricted-motion pedicle screws as well as connecting spinal rods, crossbars, connectors, and a separate locking element. The Mariner implants are manufactured from titanium alloy (Ti-6Al-4V ELI per ASTM F136) and/or cobalt chrome alloys (Co-28Cr-6Mo per ASTM F1537 or Co-35Ni-20Cr-10Mo per ASTM F562). The instruments included in the Mariner Pedicle Screw System facilitate the placement, removal, adjustment, and final locking of the system implants. Other accessories to the system include trays and caddies for storage, protection, and organization prior to and during the steam sterilization process.
The Mariner Deformity System provides additional implants and instruments that expand the functionality of the Mariner platform and provide surgeons with a comprehensive modular system to address adult deformity applications. Additional implants include pre-contoured and constrained rods, uni-planar and fenestrated screws, hooks, lateral connectors, and modular screw heads, including those with a rigidly attached rod connector, as well as instruments for pedicle subtraction osteotomy, iliac fixation, reduction, and correction.

§ 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.
