## Intended Use

The Estech Cobra Surgical System is intended for the coagulation of cardiac tissue using radiofrequency (RF) energy during cardiac surgery. The System can be used during general surgery to coagulate soft tissues. The System may also be used to coagulate blood and soft tissue to produce hemostasis.

## Device Story

The ESTECH Cobra Surgical System is an electrosurgical device used for RF ablation of cardiac and soft tissues. The ThermaShield accessory is a flat, bell-shaped silicone pad designed to provide thermal insulation between target tissue undergoing RF ablation and adjacent non-target tissue. The pad's thickness and rounded edges provide tactile feedback to the surgeon, facilitating proper placement during open chest cardiac surgery. It serves as a more convenient alternative to surgical gloves or no insulation. The system is operated by surgeons in clinical settings. The device benefits patients by protecting surrounding healthy tissue from thermal injury during ablation procedures.

## Clinical Evidence

Bench testing only. Testing demonstrated that the ThermaShield provides effective thermal insulation for adjacent tissues, performing equivalent to or better than surgical gloves. Biocompatibility was verified per ISO 10993. Electrical safety and electromagnetic compatibility were confirmed per IEC 60601-1-2 and IEC 60601-2-2.

## Technological Characteristics

The ThermaShield is a silicone pad. The system utilizes radiofrequency (RF) energy for tissue coagulation. Electrical safety conforms to IEC 60601-1-2 (EMC) and IEC 60601-2-2 (high frequency surgical equipment). Biocompatibility conforms to ISO 10993.

## Regulatory 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.

#### c. Description of Device

The ThermaShield is a flat, bell-shaped silicone pad that is designed to reliably fill the anatomic space between the target tissue of an RF ablation and adjacent non-target tissue. Its thickness and rounded edges provide tactile feedback to the surgeon and facilitates confidence in proper placement. The ThermaShield is primarily designed for use in open chest cardiac surgery.

The addition of the ThermaShield to the ESTECH Cobra Surgical System provides a more convenient option for the physician to thermally insulate surrounding non-target tissue during RF ablations. The ThermaShield is intended to improve upon

circumstances where no insulation is used or to replace the current use of a surgical glove as a thermal insulator between target and surrounding tissues (Williams, 2004; article in TAB 5).

## d. Intended Use

The Estech Cobra Surgical System is intended for the coagulation of cardiac tissue using radiofrequency (RF) energy during cardiac surgery. The System can be used during general surgery to coagulate soft tissues. The System may also be used to coagulate blood and soft tissue to produce hemostasis.

### e. Comparison to Predicate Device

The application ESTECH Cobra Surgical System with ThermaShield Accessory is identical in nearly every way to the predicate device, the ESTECH Cobra Surgical System (K051749). The only difference between the two systems is that this application requests clearance for the addition of a thermal insulation pad, known as the ThermaShield.

This SPECIAL 510(k) is being submitted only to accommodate the inclusion of the ThermaShield. Estech is not requesting any change to the Indications for Use of the ESTECH Cobra Surgical System, nor are there any technological changes being submitted for the ESTECH Cobra Surgical System.

Bench data provided in Section 18 demonstrates that the ThermaShield performs as intended and does not raise new types of safety or efficacy questions.

ESTECH concludes that the ESTECH Cobra Surgical System with ThermaShield accessory is substantially equivalent to the predicate ESTECH Cobra Surgical System.

### f. Summary of Supporting Data

The bench testing supplied in Section 18 demonstrates that the ThermaShield technology is equivalent or better than surgical gloves, commonly used clinically, in thermally insulating adjacent tissues and is an improvement over having no insulation of surrounding tissues during ablation with the previously cleared COBRA Surgical System.

The patient contacting materials of the ESTECH ThermaShield technology have been demonstrated to be biocompatible, in accordance with ISO 10993: Biological Evaluation of Medical Devices, and the safety of the electrical design is in conformance with the pertinent sections of IEC 60601-1-2, (Second Edition, 2001), Medical Electrical Equipment - Part 1-2: General Requirements for Safety - Collateral Standard: Electromagnetic Compatibility -- Requirements and Tests and IEC 60601-2-2: Medical electrical equipment - Part 2-2: Particular requirements for the safety of high frequency surgical equipment.
