Intended Use

The ARIS COBLATION Turbinate Reduction Wand, used with the WEREWOLF COBLATION System, is indicated for ablation, resection and coagulation of soft tissue and hemostasis of blood vessels in otorhinolaryngology (ENT) surgery including: nasal airway obstruction by reduction of hypertrophic nasal turbinates and submucosal tissue shrinkage.

Device Story

The ARIS COBLATION Turbinate Reduction Wand is a single-use, bipolar, radiofrequency (RF) electrosurgical device. It connects to the WEREWOLF or WEREWOLF+ COBLATION System, which includes a generator, integrated fluid module for saline delivery, and foot control. The wand features an integrated suction line, saline tube, and cable with a microchip. During ENT procedures, the system delivers RF energy to saline at the wand tip to create a plasma field, enabling precise soft tissue ablation, resection, and coagulation. The device is operated by a surgeon in an OR setting. The system provides dynamic saline flow control and user-selectable modes via a graphical interface. The output allows the surgeon to reduce hypertrophic nasal turbinates and achieve hemostasis, potentially reducing nasal airway obstruction. A tip-clearing tool is included to remove clogs during use.

Clinical Evidence

No clinical data included. Bench testing evaluated coagulation, ablation, suction, tip clearing, and mechanical/EMC performance. Pre-clinical ex vivo testing on bovine myocardial tissue demonstrated equivalent thermal zone areas and volumes compared to the predicate. Additional bench testing confirmed peak temperatures at the active electrode were lower than the predicate.

Technological Characteristics

Bipolar RF electrosurgical wand; 17-4 and 304 stainless steel shaft; Pebax and PVC tubing; 99.5% Alumina spacer; Tungsten electrodes. Dimensions: 85mm length, 2.4mm tip diameter. Connectivity: Integrated cable with microchip for 24-hour usage limit. Sterilization: Ethylene Oxide. Software: Version 4.8 (identical to K183346). Standards: IEC 60601-1, IEC 60601-2-2, IEC 60601-1-2, ISO 10993-1.

Indications for Use

Indicated for ENT surgery patients requiring ablation, resection, and coagulation of soft tissue and hemostasis of blood vessels, specifically for nasal airway obstruction due to hypertrophic nasal turbinates and submucosal tissue shrinkage.

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.
