EM3 AEM Monitor User’s Guide

 

Foreword

 

This manual and the equipment it describes are for use only by qualified medical professionals 
trained in the particular technique and surgical procedure to be performed.  This manual is 
intended as a guide for servicing the AEM Monitor, including its setup and operation.  It is not 
intended to be a general reference about the use of electrosurgery either in general application 
or in laparoscopic procedures. 

Indications for Use 

The Encision AEM Monitoring System is an accessory for use with electrosurgical generators 
and electrodes that is designed to safely deliver electrosurgical energy and to prevent injury 
caused by insulation failure and capacitive coupling. 

The AEM Monitoring System consists of two distinct functions: 

  Active electrode monitoring is intended to control stray monopolar energy caused by 

insulation failure and capacitive coupling in surgical instruments on the shaft of the 
instrument. 

  End point monitoring is intended to aid the surgeon in determining the end point of bipolar 

electrosurgical desiccation. 

Contraindications 

There are no known contraindications for use of the AEM Monitor. 

WARNING 

Prior to using the AEM System, read and review all instructions in this manual and instructions for use 

for all instruments and accessories to be used. 

CAUTION 

Federal (USA) law restricts this device to sale by or on the order of a physician. 

The AEM Monitor is designed to safely deliver electrosurgical energy and to prevent injury caused by 

insulation failure and capacitive coupling.  The Encision AEM Monitor is not intended to test for insulation 
damage on laparoscopic instruments.  Do not attempt to use this system as an instrument inspection tool. 

Conventions Used in this Manual 

WARNING 

Indicates a hazardous condition that can result in serious injury or death. 

CAUTION 

Indicates a condition that can cause a problem with the device. 

NOTICE 

Indicates an operating tip or maintenance suggestion.
