Intended Use

The intended use of the OptaBlate Radiofrequency (RF) Generator System is as follows: • Palliative treatment in spinal procedures by ablation of metastatic malignant lesions in a vertebral body. • Coagulation and ablation of tissue in bone during surgical procedures including palliation of pain associated with metastatic lesions involving bone in patients who have failed or are not candidates for standards therapy. • Ablation of benign bone tumors such as osteoid osteoma.

Device Story

System uses radiofrequency (RF) energy for bone tissue ablation; includes RF generator, splitter cable, and flexible probes with microinfusers. Used in surgical procedures to treat metastatic lesions and benign bone tumors. Access tools create curved, unipedicular pathway to tumor; flexible probe inserted into pathway; microinfuser reduces impedance events during ablation. Operated by physicians in clinical/surgical settings. Output is controlled RF energy delivery; enables unipedicular approach for tumor ablation. Benefits include pain palliation and tumor destruction in bone.

Clinical Evidence

No clinical data. Substantial equivalence supported by non-clinical testing including sterilization, biocompatibility, packaging, electrical safety, EMC testing, and design verification testing per FDA guidance for electrosurgical devices.

Technological Characteristics

Bipolar RF energy system; 500 kHz output frequency; 30W system max output (7.5W per channel). Temperature-controlled feedback mechanism. Includes flexible probes with microinfusers for unipedicular access. Sterilized components. Operates via operator-controlled RF delivery from compatible generator.

Indications for Use

Indicated for patients with metastatic malignant lesions in vertebral bodies requiring palliative treatment, patients with metastatic bone lesions who failed or are not candidates for standard therapy, and patients with benign bone tumors (e.g., osteoid osteoma). Contraindicated for vertebral body levels C1-C7.

Regulatory Classification

Dear Josh Measures:

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.

Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device"

Your device is also subject to, among other requirements, the Quality System (QS) regulation (21 CFR Part 820), which includes, but is not limited to, 21 CFR 820.30, Design controls; 21 CFR 820.90, Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review, the QS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting (reporting of medical device-related adverse events) (21 CFR Part 803) for devices or postmarketing safety reporting (21 CFR Part 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reporting-combination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.

All medical devices, including Class I and unclassified devices and combination product device constituent parts are required to be in compliance with the final Unique Device Identification System rule ("UDI Rule"). The UDI Rule requires, among other things, that a device bear a unique device identifier (UDI) on its label and package (21 CFR 801.20(a)) unless an exception or alternative applies (21 CFR 801.20(b)) and that the dates on the device label be formatted in accordance with 21 CFR 801.18. The UDI Rule (21 CFR 830.300(a) and 830.320(b)) also requires that certain information be submitted to the Global Unique Device Identification Database (GUDID) (21 CFR Part 830 Subpart E). For additional information on these requirements, please see the UDI System webpage at https://www.fda.gov/medical-devices/device-advice-comprehensive-regulatory-assistance/unique-device-identification-system-udi-system.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97).

# Device Description

The device description of the OptaBlate Radiofrequency (RF) Generator System remains consistent with that of the previously cleared K221074, with no modifications other than the incorporation of the OptaBlate Curve 10mm, 15mm, and 20mm Probe Single Kits.

The OptaBlate Curve Probe Kits provide flexible probes with microinfusers that are used with OmniCurve 10G Fracture Kits, the OptaBlate RF Generator and the Splitter Cable. Together they enable a unipedicular approach for bone tumor ablation. The access tools from the OmniCurve Kits create a curved, unipedicular pathway to the bone tumor. Based on tumor size, a flexible probe size is selected and inserted into the curved pathway. Then with the microinfuser (which reduces impedance events), the OptaBlate RF Generator and the Splitter Cable, the bone tumor is ablated.

# Substantial Equivalence Comparison

The predicate device has been identified as the OptaBlate Radiofrequency (RF) Generator System RF Generator (K221074). Both the subject and predicate device share the same intended use, and 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.
