Intended Use

The Cosman RF Injection Electrodes are used for percutaneous nerve blocks with local anesthetic solution or for radiofrequency lesioning. The nerve is localized either by electrical stimulation or by injecting contrast medium through the device and using radiography concomitantly. The nerve may then be blocked by injection of local anesthetic solution or a radiofrequency lesion is made.

Device Story

Cosman RF Injection Electrodes; used with Cosman RF Generator (K050084) for percutaneous nerve blocks or RF lesioning. Device facilitates nerve localization via electrical stimulation or contrast medium injection under radiographic guidance. Once localized, clinician performs nerve block via local anesthetic injection or creates RF lesion. Available in various lengths/gauges; includes temperature-sensing (CU, CUR, TCD, CCD) and non-temperature-sensing (CP, CR, CN) models. Single-use, sterile-packed. Used by clinicians in clinical settings.

Clinical Evidence

No clinical data. Substantial equivalence based on comparison of intended use and technological characteristics to predicate devices.

Technological Characteristics

Radiofrequency lesion probe; available in multiple lengths and gauges. Models include temperature-sensing and non-temperature-sensing variants. Single-use, sterile. Operates in conjunction with external RF generator for energy delivery and electrical stimulation.

Indications for Use

Indicated for percutaneous nerve blocks with local anesthetic or radiofrequency lesioning of nerve tissue. Used for nerve localization via electrical stimulation or contrast medium injection under radiography.

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.

Predicate Devices

• Technomed Europe RF Injection Needles (K04237)
• Cosman Medical TC Electrodes (K050084)
• Cosman Medical RF Cannula (K060799)

Device Description: The Cosman RF Injection Electrodes are used in conjunction with the commercially available Cosman RF Generator (K050084) to create radiofrequency (RF) lesions of nerve tissue or for use in percutaneous nerve blocks.. The COSMAN CU, CUR, TCD and CCD are temperature sensing RF injection electrodes. The COSMAN CP, CR and CN are non-temperature sensing RF injection electrodes. The Cosman RF Injection Electrodes are available in a variety of lefegths and gauges. The Cosman RF Injection Electrodes are provided sterile packed and are labeled for Single Use Only.

Intended Use: The Cosman RF Injection Electrodes are used for percutaneous nerve blocks with local anesthetic solution or for radiofrequency lesioning. The neve is localized either by electrical stimulation or by injecting contrast medium through the device and using radiography concomitantly. The nerve may then be blocked by injection of local anesthetic solution or a radiofrequency lesion is made.

## Comparison to Predicate:

The Cosman RF Injection Electrodes have been compared to previously 510(k) cleared devices with respect to intended use and technological characteristics. The Cosman RE Injection Electrodes have similar physical and technical characteristics to the predicate devices. The comparison and testing results in this 510(k) notification show the Cosman RF Injection Electrodes are substantially equivalent to predicate devices and are safe and effective for its intended use.
