• Applicant: Smith & Nephew, Inc.
• Product Code: GXI · Neurology
• Decision Date: Jul 16, 2009
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 882.4725
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

Smith & Nephew RF Cannulae are intended to facilitate placement of Smith & Nephew RF Denervation Probes. The Smith & Nephew RF Cannulae are indicated for use in RF heat lesion procedures for the relief of pain.

Device Story

Smith & Nephew RF Cannulae are surgical access tools designed to facilitate the placement of RF Denervation Probes during radiofrequency heat lesion procedures. The cannulae are provided in various lengths, gauges, and tip configurations (sharp or blunt; straight or curved) to accommodate different anatomical sites. The device is used by clinicians in a clinical setting to provide a pathway for the RF probe to reach the target tissue. By enabling precise probe placement, the cannulae assist in the delivery of RF energy to perform nerve ablation, which is intended to provide pain relief for the patient.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Cannulae available in 18, 20, and 22 gauge sizes with varying lengths (5cm, 10cm, 15cm) and tip configurations (sharp/blunt, straight/curved). Designed for manual insertion to guide RF probes. No energy source or software components.

Indications for Use

Indicated for use in RF heat lesion procedures for the relief of pain in patients requiring denervation probe placement.

Regulatory Classification

Identification

A radiofrequency lesion probe is a device connected to a radiofrequency (RF) lesion generator to deliver the RF energy to the site within the nervous system where a lesion is desired.

Dear Mr. Robbins:

.

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. 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.

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.

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 803); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

{2}------------------------------------------------

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please go to http://www.fda.gov/AboutFDA/CentersOffices/CDRH/CDRHOffices/ucm115809.htm for the Center for Devices and Radiological Health's (CDRH's) Office of Compliance. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to http://www.fda.gov/cdrh/mdr/ for the CDRH's Office of Surveillance and Biometrics/Division of Postmarket Surveillance.
