Description

The Avanos MIC ENFit Balloon Gastrostomy Tube is a standard-length, balloon-retained G-tube made of high-clarity medical-grade silicone. It provides access to the stomach for bolus, intermittent, or continuous enteral feeding, medication administration, and gastric decompression/venting in adult and pediatric patients when oral intake is not possible or tolerated and aspiration risk is low. This is not a low-profile button device.

Construction and features

• High-clarity, flexible silicone shaft allows visual inspection.
• Internal inflatable silicone retention balloon; external SECUR-LOK stabilization ring helps prevent inward migration.
• ENFit connectivity: available with a single gastric port or with an additional ENFit medication port; separate, clearly labeled balloon inflation/deflation port (balloon use only).
• Single gastric lumen.
• Distal tip: tapered at 12 Fr; recessed on larger sizes when the balloon is filled to the recommended volume.
• Radiopaque stripe and centimeter shaft markings for visualization and depth reference.
• Approximate tube length ~20 cm.

Sizes and balloon fill guidance

• French sizes commonly 12–24 Fr; larger sizes up to 30 Fr may be available depending on configuration.
• Typical balloon fill ranges (verify device label/IFU):
• 12 Fr: 2–3 mL (typical max ~5 mL)
• 14–16 Fr: 3–5 mL (typical max ~7 mL)
• 18–24 Fr: 7–10 mL (typical max ~15 mL)
• Always confirm the exact fill volume on the device/IFU. Inflate the balloon only with sterile/distilled water; do not use air or saline.

Placement and indications

• May be placed surgically or percutaneously under endoscopic or fluoroscopic guidance; can also be used as a replacement through an established gastrostomy tract.
• Indicated for long-term enteral nutrition, delivery of medications to the stomach, and gastric decompression/venting when clinically indicated.

Contraindications (selection)

• Colonic interposition, ascites, portal hypertension, peritonitis, uncorrected coagulopathy.
• For replacement use: uncertain tract direction/length, lack of stomach adherence to the abdominal wall, infection at the stoma, or multiple fistulous tracts.

Care and maintenance highlights

• Clean the stoma site and tube with warm water and mild soap; rinse and dry thoroughly.
• When clinically appropriate and per IFU, rotate the tube daily and position the external stabilization ring slightly off the skin (~2–3 mm) to minimize pressure injury while preventing migration.
• Use feeding/medication ports only for enteral delivery; never use the balloon valve for feeds or medications.
• Follow IFU for balloon management; many versions advise periodic (e.g., weekly) verification of balloon water volume. Stabilize the tube during inflation/deflation to avoid displacement.
• Flush with water before and after feeds and between medications; avoid acidic or carbonated irrigants unless directed by clinical guidance.

Safety, labeling, and storage

• MR Safe.
• Single-use; gamma-sterile; prescription use only.
• Not made with natural rubber latex; not formulated with DEHP, DBP, or BBP.
• Store in a cool, dry place away from heat and radiation; typical shelf life 3 years from manufacture (refer to labeling).

Components and variants

• Components: ENFit feeding port(s), balloon inflation port, external SECUR-LOK ring/disc, internal silicone retention balloon.
• ENFit connectors help reduce misconnections; size availability and the presence of a separate medication port vary by configuration—verify on the device labeling/IFU.
