Generator G11 Operator’s Manual
Chapter 1 - General Information
Indications
The Generator G11 provides radiofrequency power to drive ENSEAL electrosurgical instruments that are used during open or laparoscopic
general and gynecological surgery to cut and seal vessels and to cut, grasp, and dissect tissues� In addition, the generator provides power to
drive HARMONIC ultrasonic surgical instruments that are indicated for soft tissue incisions when bleeding control and minimal thermal injury
are desired�
ENSEAL and HARMONIC instruments, when used with the Generator G11, have not been shown to be effective for sterilization procedures
or tubal coagulation� Do not use these instruments for these procedures�
Contraindications
• The use of the Generator G11 and the attached instruments are contraindicated when, in the judgment of the physician, radiofrequency or
ultrasonic surgery would be contrary to the best interest of the patient�
• The instruments are not indicated for incising bone�
Device Description
The Generator G11 supplies energy to the HARMONIC and ENSEAL surgical instruments� The generator uses a touchscreen display interface
and has a unique receptacle port that accepts either a HARMONIC or an ENSEAL instrument� Connectors (HGA11 for HARMONIC and
EGA11 for ENSEAL) are used to enable the generator to power legacy instruments�
How Supplied
The Generator G11 is supplied in a semi-ready-to-use state� The shipping box contains the Generator G11, power cord and Operator’s Manual�
The disposable Ethicon ENSEAL or HARMONIC instruments are not included in this packaging and must be purchased separately� The
HARMONIC instrument connector (HGA11), ENSEAL instrument connector (EGA11), footswitch (FSW11) and cart (CRT11) are also
available separately�

General Warnings
• Verify that the unit is fully operational prior to administering power output for tissue sealing�
• This equipment is for use only by qualified medical personnel trained in the use of ultrasonic surgery or electrosurgery� Inappropriate use
of the equipment by untrained medical personnel may result in hazardous electrical output�
• Do not use in the presence of flammable anesthetics or oxidizing gases such as nitrous oxide (N2O) and oxygen as combustion may occur�
• Non-flammable agents should be used for cleaning and disinfection wherever possible� Flammable agents used for cleaning or
disinfecting, or as solvents of adhesives, should be allowed to evaporate before the application of electrosurgery� There is a risk of pooling
of flammable solutions under the patient or in body depressions such as the umbilicus, and in body cavities such as the vagina� Any fluid
pooled in these areas should be mopped up before the electrosurgery� Attention should be called to the danger of ignition of endogenous
or other flammable gases� Some materials, for example cotton and gauze, when saturated with oxygen may be ignited by sparks produced
in normal use during electrosurgery�
• Do not operate the Generator G11 in a moist environment as a shock hazard may exist� If liquids have entered the Generator G11, the unit
must be returned to the manufacturer for testing prior to use�
• Do not operate the unit in close proximity to volatile solvents such as methanol or alcohol as combustion may occur�
• Avoid use of the Generator G11 adjacent to or stacked with other equipment� If adjacent or stacked use is necessary, monitor the
Generator G11 and the other equipment to assure normal operation�
• Interference produced by the operation of high-frequency surgical equipment may adversely affect the operation of other electronic
medical equipment such as monitors and imaging systems�
• For patients with cardiac pacemakers or other active implants, a possible hazard exists because interference with the action of the
pacemaker may occur, or the pacemaker may be damaged� In case of doubt, approved qualified advice should be obtained�
• Use of accessories and cables other than those specified may result in unpredictable performance, increased electromagnetic emissions, or
decreased electromagnetic immunity�
• No customer modification of this equipment is allowed; modification of this equipment could have a negative impact on electrical safety
and electromagnetic emissions�
• Other than fuses, the Generator G11 contains no operator-serviceable parts� For service, return the generator to an authorized Ethicon
service facility�

5Generator G11
Generator G11 Operator’s Manual
• To avoid the risk of electric shock, this equipment must only be connected to a supply main with protective earth�
• To isolate the Generator G11 from supply mains power, disconnect the power cord either from the back panel of the generator or from the
wall� Ensure that access to these points are kept clear�
• This device is neither MR safe nor MR compatible�
• This device seals vessels up to a maximum diameter of 7 mm depending on the instrument used� Refer to the instrument Instructions For
Use (IFU) for further information�
• As with all energy sources (Electrosurgery, Lasers, or Ultrasound) there are concerns about the carcinogenic and infectious potential
of the by-products such as tissue smoke plume and aerosols� Appropriate measures such as protective eyewear, filtration masks, and
effective smoke evacuation equipment should be used in both open and laparoscopic procedures�
• In case of system failure, ensure availability of the appropriate backup equipment relevant to the specific procedure�
• After removing the instrument, examine the tissue for hemostasis� If hemostasis is not present, appropriate techniques should be used to
achieve hemostasis�
• Read instructions prior to use and follow the hospital’s clinical practice guidelines for ultrasonic surgery, electrosurgery, gynecology and
laparoscopic procedures�
• Replace fuses only with the appropriate type and rating� See System Specifications�
• Activation of a radiofrequency device when not in contact with target tissue or in a position to deliver energy may cause capacitive
coupling�
• The patient should not come in contact with metal parts which are earthed (grounded) or which have appreciable capacitance to earth (for
example operating table supports, etc�)�
• Cables to the surgical electrodes should be positioned so that contact with patient or other leads is avoided�
General Cautions
• The touch screen display of the generator is very sensitive� Do not use sharp metal objects on the touch screen�
• Removing bottom screws or opening of this device invalidates the warranty and could create hazardous conditions�
• Do not sterilize the Generator G11� Sterilization will damage the unit�
• Do not restrict the openings on the bottom and the back panel of the Generator G11, as they provide the required airflow for cooling�
• If electromagnetic interference with other equipment is suspected, reorient the device or remove possible sources of interference (for
example, cellular phones, radios, etc�) from the room�
• Monitoring electrodes should be placed as far as possible from the disposable device tips when high frequency surgical equipment and
physiological monitoring equipment are used simultaneously� Monitoring systems incorporating high frequency current-limiting devices
are recommended for use�
• Needle monitoring electrodes are not recommended�
• CRT11 is recommended if the Generator G11 is moved out of the operating room� Maintain control of the generator and cart when
moving over thresholds�

Warning
The active blade of a HARMONIC instrument heats the tissue by friction and is intended to supply sufficient friction and shearing effect to cut
and coagulate tissue in contact with the active blade� Therefore, use caution when handling the blade, clamp arm, and distal end of the shaft, as
they may be hot� Additional temperature information may be contained in individual instrument instructions for use�
