Yes
The device is a pedicle screw fixation system intended to provide temporary stabilization following spinal fusion surgery, and it is used in the treatment of various spinal instabilities and deformities.

No

The PathFinder system is described as a pedicle screw fixation system intended to provide temporary stabilization following surgery to fuse the spine. Its indications for use relate to various acute and chronic instabilities or deformities that require surgical intervention and fusion, rather than diagnosing them.

No

The device description explicitly states it is a "pedicle screw fixation system" consisting of "various screws and rods," which are physical hardware components.

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 Description and Intended Use: The description clearly states that the PathFinder system is a pedicle screw fixation system designed for surgical implantation to stabilize the spine. It is a physical implant used within the body, not a test performed on a sample outside the body.
  • Lack of IVD Characteristics: The document does not mention any of the typical characteristics of an IVD, such as analyzing biological samples, detecting biomarkers, or providing diagnostic information based on laboratory testing.

Therefore, the PathFinder - Mini-Open Posterior Approach device is a surgical implant, not an in vitro diagnostic device.

§ 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:
