Intended Use

The AccENT Head and Neck Electrosurgery System is intended for ablation and coagulation of soft tissue in otolaryngological (ENT) surgery including head, neck, oral, and sinus surgery.

Device Story

System comprises electrosurgical generator (Controller), cable, and sterile single-use bipolar wand. Wand features multi-electrode distal tip (1.5-4.5 mm diameter; 0-90 degree angles) for soft tissue ablation/coagulation. Bipolar design incorporates return electrode on shaft, eliminating need for external patient return pad and preventing energy penetration through patient body. Used in ENT surgical settings (head, neck, oral, sinus) by physicians. Controller provides high-frequency energy; no software utilized. Benefits include precise tissue management via bipolar electrosurgery.

Clinical Evidence

No clinical data provided; substantial equivalence is based on design, materials, and functional comparison to predicate devices.

Technological Characteristics

Bipolar electrosurgical system. Components: Controller (high-frequency generator), cable, and multi-electrode wand. Wand diameters 1.5-4.5 mm; tip angles 0-90 degrees. Bipolar design with integral return electrode on shaft. Sterilization: Wand (sterile/single-use); Cable (ethylene oxide or steam autoclave). No software.

Indications for Use

Indicated for ablation and coagulation of soft tissue in otolaryngological (ENT) surgery, including head, neck, oral, and sinus surgery.

Regulatory Classification

Identification

#### Device description C.

The AccENT Head and Neck Electrosurgery System is comprised of three components: the AccENT Wand, the AccENT Cable, and an electrosurgical generator called the Controller. The Cable connects the Controller to the Wand. The Wand is provided in a variety of models, ranging in diameters from 1.5 mm to 4.5 mm. The Wand offset and distal tip angles range from 0 to 90 degrees. The AccENT wand shaft is configured as straight or offset to allow for better access to the treatment area. The distal tip is configured with multi-electrodes. The Wand is supplied sterile and intended for single patient use. The Cable is designed for

{1}------------------------------------------------

repeat sterilization by either ethylene oxide gas or steam autoclaving methods, as selected by the user. The Controller is a high frequency electronic instrument. There is no software utilized in the operation of the Controller.

The AccENT Head and Neck Electrosurgery System is bipolar, incorporating a return electrode on the shaft of the device. This means that a return pad is not required for operation. The return energy in a bipolar device with an integral return electrode does not penetrate the tissue as in a monopolar device. In a monopolar device, the energy passes through the patient's body to reach the return pad.

### D. Intended use

The AccENT Head and Neck Electrosurgery System is intended for ablation and coagulation of soft tissue in otolaryngological (ENT) surgery including head, neck, oral, and sinus surgery.

# Technological characteristics E.

The technological characteristics of the AccENT Head and Neck Electrosurgery System are the same as those of the ArthroCare Arthroscopic, Dental, and General Dermatology Systems. These devices are equivalent in terms of design, materials, principle of operation, product specifications and sterilization.

## F. Summary

By virtue of design, materials, function and intended use, the AccENT Head and Neck Electrosurgery System is substantially equivalent to devices currently marketed in the United States.
