Description

The MIC-KEY (Avanos) Low‑Profile Balloon Gastrostomy Feeding Tube is a skin‑level “button” G‑tube designed for direct gastric delivery of enteral nutrition and medications, and for gastric decompression. Its unobtrusive profile helps reduce snagging and clothing interference while supporting pediatric and adult patients who cannot tolerate oral feeding and are at low risk for aspiration. This listing reflects a validated 20 Fr, 4.5 cm stoma length configuration (GTIN 00350770428239).

Indications and placement

• For gastric feeding/medication delivery and decompression.
• Placement percutaneous under fluoroscopic, laparoscopic, or endoscopic guidance; also suitable as a replacement through a mature stoma.
• Intended for pediatric and adult use when aspiration risk is low.

Contraindications

• Ascites; colonic interposition; portal hypertension; peritonitis; morbid obesity.

Materials and safety

• High‑clarity, medical‑grade silicone construction.
• Not made with natural rubber latex; not made with DEHP.
• Sterile tube, EO sterilized; single‑use. Extension sets: non‑sterile, single‑patient reusable.
• MR Conditional at 1.5 T and 3 T under the conditions specified in the IFU.

Retention and balloon

• Internal inflatable retention balloon.
• For 20 Fr: fill with 5 mL sterile or distilled water (maximum 10 mL). Do not use air, saline, or contrast media.

Connectivity and ports

• Accepts MIC‑KEY extension sets via the locking SECUR‑LOK patient‑end.
• ENFit (ISO 80369‑3) connectors on included sets for feeding/medication delivery.
• Anti‑reflux valve in the feeding port remains closed unless an extension set is attached.
• Medication port located on the ENFit Y‑connector of the continuous feed extension set.
• No jejunal port (G‑tube configuration).

Design features

• Low‑profile, skin‑level button to minimize snagging and clothing interference.
• Radiopaque stripe for visualization.
• Recessed distal tip.

Sizes and options

• French sizes: 12, 14, 16, 18, 20, 24 Fr.
