More Information

No
The summary describes a radiofrequency generator system for creating lesions and coagulating disc material, focusing on hardware and software verification for temperature control and lesion validation. There is no mention of AI or ML in the intended use, device description, or performance studies.

Yes
The device is indicated for use to create lesions during neurological lesion procedures and for the coagulation and decompression of disc material to treat symptomatic patients with contained herniated discs, which are therapeutic medical interventions.

No
The device is described as a radiofrequency generator used to create lesions or coagulate and decompress disc material, which are therapeutic procedures, not diagnostic ones.

No

The device description explicitly lists hardware components (Radiofrequency Generator, Quad Pump Unit, Therapy Cables) and the performance studies include hardware performance testing, indicating it is not a software-only device.

Based on the provided information, the COOLIEF* Radiofrequency Generator (CRG) System is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • Intended Use: The intended use describes creating lesions in neurological tissue and coagulating/decompressing disc material. These are procedures performed directly on the patient's body, not on samples taken from the body.
  • Device Description: The device generates radiofrequency energy to create heat for therapeutic purposes within the body.
  • Lack of IVD Characteristics: There is no mention of analyzing samples (blood, urine, tissue, etc.) or providing diagnostic information based on such analysis.

IVD devices are specifically designed to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. The CRG System's function is therapeutic, not diagnostic.

Device Description

The COOLIEF* Radiofrequency Generator (CRG) System uses controlled radiofrequency energy to generate heat that is used to create lesions in neurological tissues or to coagulate and decompress disc material to treat symptomatic patients with contained herniated discs. The following components of the predicate Pain Management Generator-TD (K072478), which must be used together, have been modified and are the subject of this 510(k): a) COOLIEF* Radiofrequency Generator (CRG), b) COOLIEF* Quad Pump Unit (QPU), and c) COOLIEF* Therapy Cables.

  • a) COOLIEF* Radiofrequency Generator (CRG):
    CRG is an 80-watt Radio-Frequency (RF) Generator with four independent RF channels, allowing all RF channels to be activated individually or altogether. The system is controlled via a touchscreen interface display that includes user controls, alarm messages, and on-screen selection of lesioning modalities. Like the predicate Pain Management Generator device (K072478), the CRG can operate in six treatment modes that include: Standard RF, Bipolar RF, Cooled RF, TransDiscal Monopolar RF, and TransDiscal Bipolar RF. The CRG can only be used with the other subject devices components of the COOLIEF* Radiofrequency Generator System (i.e the QPU and Therapy Cables).

  • b) COOLIEF* Quad Pump Unit (QPU):
    COOLIEF* QPU pump heads circulate fluid within a closed-loop system, using Avanos-marketed COOLIEF* fluid tubing kits, to cool the tip region of the COOLIEF* RF Probes. The QPU has four peristaltic pump heads that rotate to drive the fluid flow. The COOLIEF* QPU is controlled by the CRG and can be used with only components of the COOLIEF* Radiofrequency Generator System.

  • c) COOLIEF* Therapy Cables:
    COOLIEF* Therapy Cables are provided in the following three configurations for use with only the CRG:

    1. COOLIEF* Multi-RF Therapy Cable is used for Standard, Pulsed, or Biopolar RF treatment modes. The cable is re-usable and not intended to be in the sterile field.
    1. COOLIEF* Multi-Cooled RF Therapy Cable is used for Cooled RF treatment mode. The cable is re-usable and not intended to be in the sterile field.
    1. COOLIEF* TransDiscal* Y-Connector Therapy Cable is used for the TransDiscal Monopolar or TransDiscal Bipolar RF treatment modes. The cable is re-usable and not intended to be in the sterile field.

Each configuration of the COOLIEF* cable is compatible with only the CRG.

The subject device components of the COOLIEF* Radiofrequency Generator System can be used with the following additional COOLIEF* components that have been previously cleared: RF Probe Electrodes (i.e., Standard, TransDiscal, or Cooled) (K002389, K031951, and K163461), Cannula/Introducers (K972846, K031951, and K163236), Fluid Tubing Kit (K031951), and Split Grounding Pad (K140658).
