The description focuses on the mechanical and electrical components of the device and the RF ablation process. There is no mention of AI or ML in the intended use, device description, or performance studies.
Yes
The device is intended for the ablation of basivertebral nerves for the relief of chronic low back pain, which is a therapeutic intervention.
No
The device is an ablation system used for treating chronic low back pain by ablating basivertebral nerves, which is a therapeutic rather than a diagnostic function.
No
The device description explicitly states it is comprised of two sterile, single-use hardware components: Access Instruments and an RF Probe. It also mentions being used with an RF Generator.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices intended for use in vitro for the examination of specimens, including blood, tissue, and urine, derived from the human body, solely or principally for the purpose of providing information concerning a physiological or pathological state, or concerning a congenital abnormality, or to determine the safety and compatibility of potential donors and recipients, or to monitor therapeutic measures.
- Device Function: The Intracept Intraosseous Nerve Ablation System is a surgical device used to directly ablate nerves within the vertebral body. It is used in vivo (within the living body) to treat pain, not to analyze samples in vitro.
- Intended Use: The intended use clearly states it's for the "ablation of basivertebral nerves... for the relief of chronic low back pain." This is a therapeutic intervention, not a diagnostic test performed on a sample.
- Device Components: The components are instruments for accessing and ablating tissue, not reagents or equipment for analyzing biological samples.
Therefore, the Intracept Intraosseous Nerve Ablation System falls under the category of a therapeutic medical device, not an In Vitro Diagnostic.

Intended Use / Indications for Use
The Intracept Intraosseous Nerve Ablation System is intended to be used in conjunction with radiofrequency (RF) generators for the ablation of basivertebral nerves of the L3 through S1 vertebrae for the relief of chronic low back pain of at least six months duration that has not responded to at least six months of conservative care, and is also accompanied by either Type 1 or Type 2 Modic changes on an MRI.

Device Description
The Intracept Intraosseous Nerve Ablation System (Intracept System) is comprised of two sterile, single-use components:
- The Intracept Access Instruments include introducers, cannulas and stylets that provide access to the intended site of radiofrequency (RF) ablation.
- The Intracept RF Probe conducts RF energy to the target location.
To obtain the energy needed for tissue ablation, the Intracept RF Probe is used with the Relievant RF Generator (RFG).
The Intracept System technique uses RF ablation of the basivertebral nerve for relief of chronic low back pain and involves a two-step process. First, utilizing the Access Instruments, based on a minimally invasive, transpedicular or extrapedicular approach, a cannula and stylets are placed into the vertebral body to create a path or channel to the terminus of the basivertebral foramen. The RF Probe is then placed into this channel at the terminus of the basivertebral foramen and controlled RF energy is delivered to ablate the basivertebral nerve. This nerve has been identified as a proprioceptive sensory nerve with enervation of the vertebral endplates.

Dear Alex DiNello:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
