The description focuses on mechanical components for spinal fixation and does not mention any software, algorithms, or AI/ML capabilities.
Yes
The Blackstone Spinal Fixation System is explicitly stated to "provide immobilization and stabilization of spinal segments, as an adjunct to fusion, in treatment of acute and chronic instabilities or deformities of the thoracic, lumbar and sacral spine," which aligns with the definition of a therapeutic device designed to treat a medical condition.
No.
The Blackstone Spinal Fixation System is described as an implantable device (screws, hooks, rods, and cross connectors) used for immobilization and stabilization of spinal segments, as an adjunct to fusion. It is a treatment device, not a diagnostic one.
No
The device description explicitly states it is comprised of physical components made of titanium alloy (screws, hooks, rods, cross connectors) and is attached to the vertebral body by means of screws. This indicates it is a hardware device, not software-only.
Based on the provided information, the Blackstone Spinal Fixation System is not an IVD (In Vitro Diagnostic) device.
Here's why:
- IVD Definition: In vitro diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening.
- Blackstone Spinal Fixation System's Function: The description clearly states that the Blackstone Spinal Fixation System is a device comprised of screws, hooks, rods, and cross connectors that are attached to the vertebral body. Its intended use is to provide immobilization and stabilization of spinal segments as an adjunct to fusion for various spinal conditions.
- No Specimen Examination: The device is implanted directly into the body and does not involve the examination of any specimens taken from the patient.
Therefore, the Blackstone Spinal Fixation System falls under the category of an implantable medical device, not an in vitro diagnostic device.

(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
