Intended Use

The Stryker OptaBlate BVN Intraosseous Nerve Ablation System is intended 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 features consistent with Type 1 or Type 2 Modic changes on an MRI such as inflammation, edema, vertebral endplate changes, disruption and fissuring of the endplate, vascularized fibrous tissues within the adjacent marrow, hypointensive signals (Type 1 Modic change), and changes to the vertebral body marrow including replacement of normal bone marrow by fat, and hyperintensive signals (Type 2 Modic change).

Device Story

System uses bipolar, high-frequency electrosurgical energy to ablate basivertebral nerves for chronic low back pain relief. Components include BVN probe, Microinfuser, introducer handpiece/conduit, and access cannulas. Operated by physician in clinical setting. Probe inserted percutaneously into vertebral body; RF energy delivered via compatible generator (K221074) to create thermal lesions. Microinfuser delivers saline to ablation site to maintain electrical connection; impedance monitoring ensures safety; generator stops if impedance exceeds thresholds. Thermal coagulation of nerve tissue provides pain relief. System benefits patients by addressing specific vertebral endplate/marrow pathologies.

Clinical Evidence

No clinical data; bench testing only.

Technological Characteristics

Bipolar RF electrosurgical system. Probe: Stainless steel with gold plating, Pebax insulation, 1.75mm diameter, 10mm active length. Energy: RF, 95°C target. Connectivity: Compatible with OptaBlate RF generator and Microinfuser. Sterilization: Ethylene Oxide (probes/kits), Radiation (Microinfuser/syringe). Standards: IEC 60601-1, 60601-1-2, 60601-1-8, 60601-2-2.

Indications for Use

Indicated for patients with chronic low back pain (≥6 months) unresponsive to ≥6 months of conservative care, presenting with Type 1 or Type 2 Modic changes on MRI (e.g., inflammation, edema, endplate disruption, marrow fat replacement) at L3-S1 vertebrae.

Dear Dayana Manganese:

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 (the 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 available 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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

# Device Description

The subject device Stryker Optablate® BVN Intraosseous Nerve Ablation System is a bipolar, high frequency electrosurgical system comprising the BVN probe, Microinfuser, syringe, introducer handpiece, introducer conduit, 10 G access cannula with diamond tip stylet, and 10 G bevel tip stylet.

The subject device is intended to be used in conjunction with the existing Optablate radiofrequency (RF) generator (K221074), MultiGen2 Splitter Cable (K170242), and Optablate Microinfuser (K221074) to produce lesions by the direct application of radiofrequency currents for the relief of chronic low back pain. The subject generator applies temperature-controlled, radiofrequency (RF) energy into the probe. During lesion creation, targeted tissue is exposed to RF energy using an active probe inserted into a conduit that is within an access cannula. The application of RF energy causes a thermal reaction at the targeted tissue site to ablate the basivertebral nerve. It is indicated for the L3 through S1 vertebrae.

When used, the subject OptaBlate BVN probes are connected to the splitter cable, which is connected to the generator, to deliver RF energy to the target tissue. The OptaBlate Microinfuser is connected to the probe to deliver a small amount of saline to the ablation site. The saline exits the probe between the emitters and helps ensure there is good electrical connection between the emitters and the tissue. The quality of the connection is measured in units called impedance. Impedance goes up if the connection is poor. If the impedance goes to high, the generator will trigger an error and stop the ablation. The Microinfuser slowly introduces saline to prevent impedance rises.

# Indications for Use

The Stryker OptaBlate BVN Intraosseous Nerve Ablation System is intended 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 features consistent with Type 1 or Type 2 Modic changes on an MRI such as inflammation, edema, vertebral endplate changes, disruption and fissuring of the endplate, vascularized fibrous tissues within the adjacent marrow, hypointensive signals (Type 1 Modic change), and changes to the vertebral body marrow including replacement of normal bone marrow by fat, and hyperintensive signals (Type 2 Modic change).

# Substantial Equivalence Comparison

The predicate device has been identified as the Intracept Intraosseous Nerve Ablation System Relievant Medsystems RF Generator (RFG) (K190504). Both subject and predicate devices share the same intended use, and similar indications for use and technological characteristics. Results of verification and validation demonstrate that these differences do not introduce new questions of safety and effectiveness. The subject devices are at least as safe and effective as the predicate device.

## Conclusion

The subject devices, in comparison with the legally marketed predicate, share the same intended use and operating principles. Performance testing demonstrate that the subject devices are at least as safe and effective as the predicate. Any differences between the subject and predicate devices do not raise any new or different types of questions of safety and effectiveness. A determination of substantial equivalence is supported.
