Intended Use

Sutter RaVoR™ Bipolar Electrodes are to be connected to the Sutter CURIS® RF Generator. Sutter Ra VoR™ Bipolar Electrodes are indicated for ablation of soft tissue in otorhinolaryngology (ENT) surgery. The Ra VoR™ Bipolar Electrode for the soft palate is indicated for submucosal tissue coagulation in the uvula/soft palate for the treatment of snoring. The RaVoR™ Bipolar Electrode for the turbinates is indicated for submucosal tissue shrinkage for reduction of hypertrophic nasal turbinates in patients with nasal turbinate airway obstruction.

Device Story

Sutter RaVoR™ Bipolar Electrodes are electrosurgical instruments designed for connection to the Sutter CURIS® RF Generator. The device delivers radiofrequency energy to soft tissue in ENT procedures; specifically for submucosal shrinkage or coagulation. The electrodes feature various angled sheath configurations and are single-use, sterile devices. Operation is performed by qualified medical personnel in a clinical setting. The device functions by applying bipolar RF energy to target tissues, resulting in controlled thermal effects (lesions) for tissue reduction. The healthcare provider uses the device to treat snoring or nasal airway obstruction; the resulting tissue shrinkage/coagulation provides therapeutic benefit by reducing tissue volume. The device is substantially equivalent to the predicate Celon ENT System.

Clinical Evidence

No clinical or animal studies were performed. Substantial equivalence is supported by bench testing, including electromagnetic compatibility, electrical safety (IEC 60601-1, 60601-2-2, 60601-1-2), mechanical strength, thermal damage/spread experiments, and biocompatibility (ISO 10993-1).

Technological Characteristics

Materials: Stainless steel, Fluoropolymer, Polyester. Energy: Bipolar RF. Design: Parallel electrode configuration, various angled sheaths. Connectivity: Connects to Sutter CURIS® RF Generator. Sterilization: Ethylene Oxide (SAL 10^-6). Standards: IEC 60601-1, IEC 60601-1-2, IEC 60601-2-2, ISO 11137-1/2, ISO 10993-1.

Indications for Use

Indicated for ENT soft tissue ablation/coagulation. Specifically: submucosal tissue coagulation in uvula/soft palate for snoring treatment; submucosal tissue shrinkage for reduction of hypertrophic nasal turbinates in patients with nasal turbinate airway obstruction.

Regulatory Classification

Identification

An electrosurgical cutting and coagulation device and accessories is a device intended to remove tissue and control bleeding by use of high-frequency electrical current.
