Intended Use
When intended to promote fusion of the cervical spine and occipito-cervico-thoracic junction (occiput-T3), the Blackstone Ascent POCT System is indicated for: a) degenerative disc disease (defined as neck pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies; b) spondylolisthesis; c) fracture/dislocation; d) spinal stenosis; e) atlanto-axial fracture with instability; f) occipito-cervical dislocation; g) tumors; h) revision of previous cervical spine surgery The occipital bone screws are limited to occipital fixation only. The use of the multi-axial screws is limited to placement in the upper thoracic spine (T1-T3) for the treatment of thoracic conditions only. They are not intended to be placed in the cervical spine. The lateral offset adapter is indicated for use in the upper thoracic spine (T1-T3). The hooks are intended to be placed from C1 to T3. The Songer Cable (titanium) System to be used with the Blackstone Ascent Posterior Occipital Cervical Thoracic System allows for wire/cable attachment to the posterior cervical spine. The Blackstone Ascent Posterior Occipital Cervical Thoracic System can also be linked to the Blackstone Spinal Fixation System using the Blackstone Ascent Axial Connector.
Device Description
The Blackstone Ascent POCT System is a temporary, titanium alloy, multiple component system comprised of a variety of non-sterile, single use components that allow the surgeon to build a spinal implant construct. The Ascent POCT System consists of an assortment of rods, setscrews, cross connectors, axial connectors, lateral offset adapters, multi-axial screws, hooks, plates, bone screws, and Songer Cables.

No
The provided text describes a mechanical spinal fixation system and does not mention any AI or ML components or functionalities.

Yes

The device is intended to promote fusion of the cervical spine and occipito-cervico-thoracic junction to treat various medical conditions such as degenerative disc disease, spondylolisthesis, fracture/dislocation, spinal stenosis, and tumors. This aligns with the definition of a therapeutic device designed to treat or alleviate a disease or condition.

No

This device is described as a "temporary, titanium alloy, multiple component system comprised of a variety of non-sterile, single use components that allow the surgeon to build a spinal implant construct" to promote fusion of the cervical spine. This is a surgical implant, not a diagnostic device.

No

The device description explicitly states it is a "temporary, titanium alloy, multiple component system comprised of a variety of non-sterile, single use components" including rods, screws, hooks, plates, etc. These are clearly hardware 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 Description: The Blackstone Ascent POCT System is described as a "temporary, titanium alloy, multiple component system comprised of a variety of non-sterile, single use components that allow the surgeon to build a spinal implant construct." This clearly indicates a physical implant used within the body during surgery.
  • Intended Use: The intended use is to "promote fusion of the cervical spine and occipito-cervico-thoracic junction." This is a surgical procedure, not a diagnostic test performed on a sample.

The device is a surgical implant used for spinal fixation and fusion, which falls under the category of medical devices, but not specifically In Vitro Diagnostics.

§ 888.3050 Spinal interlaminal fixation orthosis.

(a)
Identification. A spinal interlaminal fixation orthosis is a device intended to be implanted made of an alloy, such as stainless steel, that consists of various hooks and a posteriorly placed compression or distraction rod. The device is implanted, usually across three adjacent vertebrae, to straighten and immobilize the spine to allow bone grafts to unite and fuse the vertebrae together. The device is used primarily in the treatment of scoliosis (a lateral curvature of the spine), but it also may be used in the treatment of fracture or dislocation of the spine, grades 3 and 4 of spondylolisthesis (a dislocation of the spinal column), and lower back syndrome.(b)
Classification. Class II.
