Description

The Avanos MIC-KEY Low-Profile Gastric-Jejunal (GJ) Feeding Tube Kit (ENFit) is a skin-level, double-lumen device placed through a gastric stoma with the distal limb positioned in the jejunum. It supports simultaneous post-pyloric feeding and gastric decompression/venting for pediatric and adult patients.

Intended use

• Provides jejunal feeding while allowing gastric decompression/venting via a separate lumen.
• Skin-level “button” design intended for comfort, discretion, and low profile under clothing.

Design and retention

• Low-profile button with external bolster and internal inflatable balloon for retention.
• Tungsten-weighted jejunal segment to help maintain jejunal placement.
• Tapered distal tip to aid placement.
• Radiopaque stripe for visibility under imaging.
• Multiple distal jejunal exit ports to distribute feeds.
• Clearly marked gastric and jejunal ports for identification.

Ports and valves

• Three labeled access points:
• JEJUNAL: delivers nutrition into the small intestine.
• GASTRIC: enables decompression/venting of the stomach via gravity or low intermittent suction.
• BAL: for balloon inflation/deflation.
• One-way valves in the JEJUNAL and GASTRIC ports open when a MIC-KEY extension set is attached.
• No dedicated medication port; medications may be administered via the jejunal or gastric port per clinical direction.

Connectivity and extension sets

• ENFit connectivity for enteral-only connections.
• Accepts MIC-KEY extension sets; kit includes ENFit extension sets for continuous (right‑angle) and bolus (straight) feeding.
• MIC-KEY SECUR-LOK interface on the button for secure attachment of extension sets.

Materials and safety

• Medical-grade silicone construction; not made with natural rubber latex.
• Not formulated with DEHP, DBP, or BBP.

Placement and measurement

• Intended for endoscopic or radiologic placement; suitable as an initial or replacement tube per clinical judgment.
• Jejunal length is measured from the distal aspect of the retention balloon to the catheter tip.

Sizes and options

• French sizes: 14 Fr, 16 Fr, 18 Fr, 22 Fr.
• Jejunal lengths: 15 cm, 22 cm, 30 cm, 45 cm (availability varies by French size).
• Stoma lengths: approximately 1.0 cm to 7.0 cm (availability varies by tube diameter).

Sterility and use conditions

• Supplied sterile; gamma sterilized.
• Single-use; prescription device (Rx only). Do not reuse, reprocess, or re-sterilize.

Contraindications/cautions (summary)

• May be contraindicated in patients with ascites, colonic interposition, portal hypertension, peritonitis, or morbid obesity. Follow institutional protocols and clinician judgment.

Typical kit contents

• MIC-KEY GJ tube; ENFit extension sets for continuous and bolus feeding; closure caps and clamps. Accessory items such as syringes and gauze pads are commonly included.
