Low Profile Button G-J Tube
Low-Profile Gastric and Jejunal Balloon Feeding Tube.
AMT G-JET® Button Anatomy
GASTRIC Port (White)
Most often used to decompress the stomach and administer medication as prescribed by your physician.
Low profile 4-point design offers maximum stability for increased comfort and decreased irritation.
Device Size & Lot Number
The device size and lot number is laser engraved on the top of the device for complete traceability.
Port Covers w/ Safety Plug
Gastric and Jejunal ports can be opened and closed independently of one another.
JEJUNAL Port (Glow Green)
Most often used to administer formulas into the jejunum.
Anti-Reflux/One Way Valve
Located in the bottom of the gastric and jejunal ports to prevent stomach contents from leaking out of the tube.
The balloon is inflated and deflated by inserting a slip tip syringe into the balloon valve. Note: Do NOT attempt to feed through the balloon valve.
Internal Retention Balloon
A balloon is inflated inside the stomach to hold the tube in place.
Spring reinforcement maintains superior flow. Approved for MRI, device is MR Conditional.
Easier Nighttime Connections

The G-JET® Button’s unique internal tube geometry addresses clogging with a whole new profile. Unlike other G-J buttons, our tube transforms from a tri-lumen design in its proximal (gastric) segment to a single large lumen in its distal (jejunal) segment.
The design of the AMT G-JET’s jejunal lumen supports increased flow. The lumen offers a 69% larger cross sectional area and eliminates all sharp corners and small spaces to help prevent clogging.
With less clogging, fewer tube replacements may be required.
Independent third party testing has shown significantly longer balloon life under controlled laboratory acid test conditions when comparing the AMT MiniONE® balloon to the leading competitor balloon. The AMT G-JET® has the same balloon as the MiniONE®.
14 French: The Smallest G-J Tube in the World
The AMT G-JET® Button is the only G-J tube available in a 14F size, making it the smallest G-J tube in the world!
Watch for the AMT G-JET in 18F sizes, coming soon!
Reduced Risk of Misconnections
Accidentally feeding the stomach instead of the jejunum can be dangerous! The G-JET® Button addresses this in multiple ways.
- Gastric (stoma) length is printed on the “G” strap
- Jejunal length is printed on the “J” strap and laser engraved on the external bolster
- G and J safety plugs have distinctive shapes for tactile differentiation
- Gastric feed set will ONLY fit the gastric (white) port.
- Jejunal feed set will ONLY fit the jejunal (glow green) port.
**Please note that due to mutual exclusivity, it is extremely important to ensure you always have a stock of both the gastric (white) and jejunal (glow green) extension sets available.

Device Related Concerns:
AMT has provided this information as an educational resource tool. This is not intended as a substitute for professional medical care and advice. The FIRST source of information should be your healthcare provider.
Leakage Around the Device:
- Make sure the balloon is filled with the prescribed amount of water (resistance should be felt when gently pulling on the tube.) NOTE: The recommended fill volume is printed on top of the fill valve. If you have questions contact your healthcare provider.
- Check that the G-J tube corresponds to the prescribed French size and length. If the incorrect device is in place, call your doctor.
- The G-J tube may be too tight or too loose. Call your doctor to have the stoma remeasured.
For new placements, it may take time for the stoma tract to naturally heal, firm up around the tube, and conform to the balloon. If leaking persists contact your healthcare provider.
- With each placement the stoma length should be measured with the AMT Stoma Measuring Device.
- Causes for Leakage:
- Incorrect size
- Weight change
- Amount of water in balloon may be too much or too little
- Tension at stoma site
- Stomach may need to be decompressed
Balloon Related Concerns:
- A balloon may leak or deflate over time due to medications, balloon inflation volume, stomach acid, G-tube care, or natural wear. ALWAYS have a spare G-tube, like the AMT’s MiniONE® Balloon Button, to place in the stoma tract that is similar in size to your G-JET® device. This will aid in keeping the stoma tract from closing. Once a temporary replacement device is in place call your doctor.
Do NOT remove G-J tube until a replacement is available in order to prevent the stoma from closing.
Balloon Will Not Deflate:
- Clean the balloon port with a cotton swab to make sure formula/medication or other contaminants are not blocking the balloon port. Insert a slip tip syringe, push and twist one-quarter turn. If the balloon still will not deflate, please contact our Enteral Product Specialists by calling 800-869-7382. If the problem persists call your doctor.
Feeding Set Becomes Disconnected:
Stop the feeding pump and estimate the amount of formula lost. Wipe tube connections thoroughly with soap and water. Clean the inside of the feed set and the device feeding port with a clean cotton swab and soap and water. Dry connectors and reconnect tubes. Resume feeding, adding additional formula for the estimated loss.
Preventing Tube Blockage/Clogging:
- Flush the G-J tube with 5ml (10-20ml for adults) of warm water before and after administering food or medication or every 6 hours for continuous feeding. DO NOT place foreign objects down the center of either port on the G-J tube.
- DO NOT mix medications with formula while feeding. Always administer medications one at a time and thoroughly clean the extension set. Try to obtain your medications in liquid form when possible. If only available in tablet form ask your pharmacist if it is safe to crush the tablet into a fine powder and mix with warm water.
G-J Tube is Too Tight Against the Patient's Skin:
The G-J tube should be able to move slightly from side to side easily without resistance from the patient’s skin. If the G-J tube does not move easily or redness/bleeding occurs at the stoma site or the area directly underneath the G-J tube, call your doctor. The patient may need to be remeasured for a longer G-J tube.
With each placement the stoma length should be measured with the AMT Stoma Measuring Device.
G-J Tube is Pulled Out of the Patient:
Although the G-J tube is designed to decrease the number of pull outs, a G-J tube may become accidentally dislodged. ALWAYS have a spare G-tube, like the AMT’s MiniONE® Balloon Button, to place in the stoma tract that is similar in size to your G-JET® device. This will aid in keeping the stoma tract from closing. Once a temporary replacement device is in place call your doctor.
Contact your healthcare provider if you or your patient are experiencing vomiting.
Aspiration (inhalation of food or stomach contents into the lungs) may occur while vomiting, causing difficulty in breathing or other serious medical conditions. Stop feeding and decompress the stomach immediately if vomiting occurs.
Contact emergency care immediately if difficulty in breathing occurs or aspiration is suspected. DO NOT feed while the patient is laying flat.
Contact your healthcare provider if you or your patient are experiencing Diarrhea.
This may occur if formula has spoiled. Mix new formula before each feeding. Cleanliness is also very important. All caregivers should wash their hands thoroughly prior to preparing the formula and handling the feed sets. Make sure the feeding sets are rinsed thoroughly to avoid soap in the formula. Call your doctor if diarrhea continues.
Contact your healthcare provider if you or your patient are experiencing Constipation.
This may occur due to dehydration, inactivity, feeding routine, or change in formula or medication. Call your doctor if this continues.
This may occur if too much formula is administered or if the formula is delivered too quickly. Call your doctor if this continues.
Stoma Site Related Concerns:
Contact your physician if any of the following are observed:
- If the skin around the stoma is red or raw
- If there is drainage around the site that is white, yellow or green
- If drainage from the site has a foul odor
- If crusting is noted at the site
- If repetitive leakage of food or stomach contents (gauze or pads should not be necessary)
- If pain at the G-J stoma site
- If bleeding, puss or inflammation at the G-J stoma site
If the tube begins to migrate or becomes dislodged, immediately consult your physician.
If the tube completely falls out of the stoma tract, your physician may suggest that you temporarily place a g-tube in the stoma tract to aid in keeping it from closing until a new G-JET device can be placed. For this reason, it may be helpful to always keep a spare g-tube on hand, like AMT’s MiniONE® Balloon Button.
