Intended Use

The Isolator® linear pen is a sterile, single use electrosurgery device intended to ablate cardiac tissue during cardiac surgery using radiofrequency (RF) energy when connected directly to the ASU or ASB in Ablation mode. The Isolator® linear pen may be used for temporary cardiac pacing, sensing, recording, and stimulation during the evaluation of cardiac arrhythmias during surgery when connected to a temporary external cardiac pacemaker or recording device.

Device Story

Isolator Linear Pen is a sterile, single-use electrosurgical instrument; used during cardiac surgery. Input: bipolar radiofrequency (RF) energy from AtriCure Ablation and Sensing Unit (ASU) or ASU Source Switch (ASB). Operation: operator controls RF energy delivery via footswitch to ablate cardiac tissue; device also functions as a surgical tool for temporary cardiac pacing, sensing, recording, and stimulation when connected to external auxiliary equipment. Output: thermal ablation of cardiac tissue or electrical signals for cardiac monitoring/pacing. Used in surgical settings by clinicians. Benefits: enables precise cardiac tissue ablation and intraoperative arrhythmia evaluation.

Clinical Evidence

Bench testing only. Testing conducted per 21 CFR 820.30 and AtriCure's Quality System to verify conformance to design controls and specifications. Biocompatibility testing conducted in accordance with ISO 10993-1.

Technological Characteristics

Electrosurgical device; bipolar RF energy source; single-use; sterile. Materials tested for biocompatibility per ISO 10993-1. System components include Pen, ASU, ASB, and footswitch.

Indications for Use

Indicated for patients undergoing cardiac surgery requiring ablation of cardiac tissue or evaluation of cardiac arrhythmias via temporary pacing, sensing, recording, or stimulation.

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.

#### Intended Use

The Isolator® linear pen is a sterile, single use electrosurgery device intended to ablate cardiac tissue during cardiac surgery using radiofrequency (RF) energy when connected directly to the ASU or ASB in Ablation mode. The Isolator® linear pen may be used for temporary cardiac pacing, sensing, recording, and stimulation during the evaluation of cardiac arrhythmias during surgery when connected to a temporary external cardiac pacemaker or recording device.

#### Cleared Device

The device proposed for modification in this submission is the Isolator® linear pen cleared via 510(k) K100501 on June 18, 2010.

#### Device Description

The Isolator™ linear pen System is comprised of the AtriCure® Ablation and Sensing Unit (ASU), Isolator™ linear pen (Pen), Footswitch, ASU Source Switch(ASB). The Pen is a single patient use electrosurgical instrument designed for use only with the ASU and ASB. The Pen is used to ablate cardiac tissues and as a surgical pacing and mapping tool. When the Pen is connected to the ASU, the ASU provides the bipolar radiofrequency (RF) energy flowing between both electrodes of the Pen. The Operator controls the application of this RF energy by pressing the Footswitch. When the Pen is connected to an auxiliary pace, sense, or stimulation device, the Pen is designed to provide temporary pacing or monitoring.

#### Materials

All materials in the modified Isolator® linear pen are suitable for their intended use. Testing was conducted on all patient contacting materials in accordance with ISO 10993-1 to ensure appropriate biocompatibility of all appropriate materials.
