Intended Use

The COOLIEF* Cooled Radiofrequency Kit Advanced is to be used in conjunction with the Radiofrequency (RF) Pain Management Generator (PMG-ADVANCED) or the COOLIEF* Radiofrequency Generator (CRG-Advanced) to create lesions in nervous tissue. The device includes a fluid delivery system for commonly used fluid agents limited to contrast medium, saline, and/or anesthetic solution delivery at the target site. This device is also indicated for creating radiofrequency lesions of the genicular nerves for the management of moderate to severe knee pain of more than 6 months with conservative therapy, including medication, in patients with radiologically-confirmed ostecarthritis (grade 2-4) and a positive response (≥50% reduction in pain) to a diagnostic genicular nerve block.

The COOLIEF® SINERGY* Cooled Radiofrequency Kit Advanced is to be used in conjunction with the Radiofrequency (RF) Pain Management Generator (PMG-ADV ANCED) or the COOLIEF* Radiofrequency Generator (CRG-ADVAN CED) to create RF lesions in nervous tissue. The device includes a fluid delivery system for commonly used fluid agents limited to contrast medium, saline, and/or anesthetic solution delivery at the target site.

Device Description

The COOLIEF* Cooled Radiofrequency Kit Advanced is a modification to the predicate COOLIEF* Cooled Radiofrequency Kit cleared under K163461. The subject device consists of the following:

  • COOLIEF* Cooled Radiofrequency Probe Advanced
  • COOLIEF* Cooled Radiofrequency Fluid Tubing Kit ●
  • COOLIEF* Cooled Radiofrequency Fluid Delivery Introducer ●

The modifications to the subject device are specific to the probe and fluid tubing kit.

The subject probe and fluid tubing kit are also included in the COOLIEFSINERGY Cooled Radiofrequency Kit Advanced.

The subject device has several configurations based on the anatomic region of use, length of the introducer and probe, and the length of the active electrode. The COOLIEF* Cooled Radiofrequency Kit Advanced is composed of fluid delivery introducers, probes, and fluid tubing kit. The kit is sterile, non-pyrogenic, and single-use. The COOLIEF* Cooled Radiofrequency Kit Advanced is to be used in conjunction with the Radiofrequency (RF) Pain Management Generator (PMG-ADVANCED) or the COOLIEF* Radiofrequency Generator (CRG-Advanced) to create lesions in nervous tissue.

The COOLIEF* SINERGY* Cooled Radiofrequency Kit Advanced is to be used in conjunction with the Radiofrequency (RF) Pain Management Generator (PMG-ADVANCED) or the COOLIEF* Radiofrequency Generator (CRG-ADVANCED) to create RF lesions in nervous tissue. This device includes the same components as the COOLIEF* Cooled RF Kit Advanced, but also includes an Epsilon The Epsilon Ruler is a circular stainless-steel ruler that may be used during the COOLIEF Ruler. SINERGY* procedure to assist the user in providing a 'template' around the foramen, which is specific to performing procedure around the sacroiliac (SI) nerve.

2. Sample Size Used for the Test Set and Data Provenance

The document explicitly states that clinical data was not applicable for the subject device and therefore was not provided. All testing mentioned is "non-clinical testing" or "bench performance testing." The sample sizes for these non-clinical tests are not specified in the provided text, nor is the provenance of the data beyond being "bench performance testing."

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

This information is not applicable as there was no clinical study described that involved establishing a ground truth with experts. The stated tests are non-clinical, focusing on device performance and safety parameters.

4. Adjudication Method for the Test Set

This information is not applicable as there was no clinical study described. Adjudication methods are typically relevant for human-led assessments in clinical trials.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, If So, What Was the Effect Size of How Much Human Readers Improve with AI vs. Without AI Assistance

This information is not applicable. The device described is a radiofrequency kit, not an AI-powered diagnostic or assistive tool for human readers. There is no mention of AI or MRMC studies in the provided text.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

This information is not applicable. The device is hardware (a radiofrequency kit) and not an algorithm.

7. The Type of Ground Truth Used

This information is not applicable as no clinical studies with a ground truth were conducted or described. The "ground truth" for the non-clinical tests would be the established engineering and safety standards and specifications to which the device was tested.

8. The Sample Size for the Training Set

This information is not applicable. The device is a physical medical device, not a machine learning algorithm that requires a training set.

9. How the Ground Truth for the Training Set Was Established

This information is not applicable. As stated above, the device does not involve a training set or ground truth in the context of an algorithm.
