Syringe
• Do not insert the instrument into the endoscope unless you have a clear endoscopic field of view. If you
cannot see the distal end of the insertion portion in the endoscopic field of view or in x-ray images, do not use
it. This could pose a risk of perforation, bleeding or mucous membrane damage. It may also damage the
endoscope or instrument.
• Do not angulate the insertion portion of the endoscope or operate the forceps elevator while the distal end of
the insertion portion is extended from the distal end of the endoscope. This could result in perforation,
bleeding or mucous membrane damage.
• Do not force the distal end of the insertion portion against body cavity tissue. This could result in perforation,
bleeding or mucous membrane damage.
• Do not inflate the balloon with any syringes other than attached pre-measured syringes. Otherwise, the
balloon may burst and the bursted pieces could remain in the duct. This could result in mucous membrane
damage.
• Do not inflate the balloon rapidly. The balloon may burst and the bursted pieces could remain in the duct. This
could result in mucous membrane damage.
• Inflate the balloon with air only. Inflation with anything other than air may hinder contraction of the balloon and
make it impossible to withdraw the instrument from the body cavity.

Inserting into the endoscope
• Confirm that the balloon is completely deflated when inserting the instrument into the endoscope. If the
balloon is inflated, the distal end of the instrument may extend from the distal end of the endoscope abruptly.
This could cause patient injury, such as perforation, bleeding or mucous membrane damage, and could
damage the endoscope and/or instrument.
• When using a guidewire, hold the guidewire while inserting the instrument. Otherwise, the guidewire will
move with the instrument. This could cause patient injury, such as perforation, bleeding or mucous
membrane damage.
• Be sure to raise the forceps elevator to its maximum height. If the forceps elevator is down, you will not be
able to see the distal end of the insertion portion in the endoscopic field of view. This could cause patient
injury, such as perforation, bleeding or mucous membrane damage.
• Do not force the instrument if resistance to insertion is encountered. Reduce the angulation (or lower the
forceps elevator if applicable) until the instrument passes smoothly. The use of excessive force causes
patient injury, such as perforation, bleeding or mucous membrane damage. It may also damage the
endoscope and/or instrument.
• Do not advance or extend the instrument abruptly. This could cause patient injury, such as perforation,
bleeding or mucous membrane damage. It could also damage the endoscope and/or instrument.
• When inserting the instrument into the endoscope, hold it close to the biopsy valve and keep it as straight as
possible relative to the biopsy valve. Otherwise, the insertion portion could be damaged.
• Do not excessively curve the instrument forcibly. Excessive bending force could prevent smooth passage of
the guidewire.
1. Raise the forceps elevator to its maximum height.
2. Carefully insert the instrument into the biopsy valve.
3. When using a guidewire, hold the guidewire in position and insert the instrument into the endoscope along the
guidewire.
4. When the distal end of the insertion portion contacts the forceps elevator, lower the forceps elevator.
If the entire V marking is outside the biopsy valve, the distal end of the inserted instrument has not advanced
as far as the endoscope’s forceps elevator. When the distal end of the V marking comes near the biopsy
valve, the distal end of the instrument is very close to the forceps elevator.
5. Advance the instrument another 20 mm and raise the forceps elevator. You will see the distal end of the instrument
in the endoscopic field of view.
If the forceps elevator is down, you will not see the distal end of the instrument in the endoscopic field of view.
It will only be possible to see the instrument if you raise the forceps elevator gradually.
Attaching or removing the hook
When attaching the hook to the boot of the endoscope, be careful not to make the guidewire port face a
patient. When the instrument is used with the guidewire, the end of the guidewire could contact the patient’s
face. This could cause patient injury.
When attaching or removing the hook, do not hold far from the hook. This could damage the instrument.
The control section of this instrument can be attached to the endoscope or ET control device using the hook.
1. Push the hook onto the boot of endoscope or ET control device until it clicks (see Figure 1).
2. Confirm that the hook is secured and the control section of instrument can be attached to the endoscope or ET
control device.
3. When removing the hook, pull it gently.
– 6 –
Page 7
Attaching or removing the connector
When attaching or removing the connector, do not hold far from the connector. This could damage the
instrument.
When removing the connector from the guidewire port, the air feeding port and the injection port can be
separated from the guidewire port.
1. Detach the connector from the guidewire port if necessary (see Figure 2).
2. When attaching the connector to the guidewire port, push it into the groove until it clicks (see Figure 2).
Radiography, injecting medical fluid and retrieval
Do not operate the instrument abruptly or with excessive force when retrieving a foreign object. Otherwise,
patient injury, such as bleeding or mucous membrane damage, may occur or the balloon may burst and the
bursted pieces could remain in the duct.
1. Connect a sterile syringe filled with a contrast medium, medical fluid or saline solution to the injection port. Inject
the fluid until the air inside the tube is forced out.
2. Insert the distal end of the instrument into the target site.
3. Confirm that the stopcock is open (see Figure 3).
4. Select a pre-measured syringe according to the size of the balloon being used (Balloon size is indicated on each
syringe).
5. Pull the plunger of the syringe until it stops and mount the syringe onto the air feeding port.
6. Push the plunger until it stops to inject air into the balloon.
When using the pre-measured syringe for ø 15.0 mm inflation, the marks on the syringe provide approximate
position of the distal end of Gasket for ø 8.5 mm or ø 11.5 mm inflation.
7. Turn the knob on the stopcock 90° clockwise to close the stopcock.
8. Depress the syringe’s plunger to inject the fluid.
9. Pull the instrument to clear the foreign object.
Withdrawing the instrument from the endoscope
Do not withdraw the instrument from the endoscope quickly. This could scatter blood, mucus or other patient
debris and pose an infection control risk.
• Do not withdraw the instrument from the endoscope while the balloon is inflated. This could damage the
endoscope and/or instrument.
• When using an endoscope equipped with a forceps elevator, do not withdraw the instrument from the
endoscope if the forceps elevator is up. This could damage the instrument.
• If resistance is too strong and withdrawal is difficult, adjust the angle of the endoscope until the instrument
can be withdrawn smoothly. Forcible withdrawal could damage the instrument and/or endoscope.
• Do not withdraw the syringe’s plunger in order to deflate the balloon when the stopcock valve is closed. The
balloon cannot be deflated if the stopcock valve is closed, even if the syringe’s plunger is withdrawn.
1. Turn the knob on the stopcock 90° counterclockwise to open the stopcock (see Figure 3).
2. Pull out the pre-measured syringe’s plunger to deflate the balloon.
3. Lower the forceps elevator.
4. Withdraw the instrument from the endoscope.
When the entire V marking is outside the biopsy valve, the distal end of the instrument has been retracted
into the endoscope’s instrument channel, and is now proximal to the forceps elevator. When using an
endoscope with the guidewire stabilizing function, the forceps elevator may now be raised to stabilize the
guidewire.
