Description

The Avanos MIC-KEY Low-Profile Gastric-Jejunal (GJ) Feeding Tube with ENFit kit provides skin-level access for simultaneous jejunal feeding and gastric decompression in pediatric and adult patients. This dual-lumen, low-profile “button” device is placed through a gastric stoma with the distal limb positioned in the jejunum to support post-pyloric feeding while allowing gastric venting via a separate lumen.

Intended use and indications

• Provides continuous or bolus jejunal feeding while enabling gastric decompression/venting as directed.
• Designed for discreet, comfortable, skin-level access for long-term enteral therapy.

Design and ports

• Low-profile external bolster with an internal inflatable balloon retainer.
• Three access points: JEJUNAL (feeding), GASTRIC (decompression/venting), BAL (balloon inflation/deflation).
• One-way valves in the JEJUNAL and GASTRIC ports open only when a MIC-KEY Extension Set is attached.
• No dedicated medication port; medications may be delivered via the jejunal or gastric port per clinical direction.

Connectivity and kit configuration

• ENFit connector configuration.
• Uses MIC-KEY extension sets; kit includes ENFit extension sets for continuous and bolus feeding.
• Also available in catheter-tip connector variants within the product family (availability depends on configuration).

Key features

• Weighted jejunal segment to help maintain placement.
• Multiple jejunal exit ports for distribution.
• Radiopaque stripe for visualization on imaging.
• Tapered distal tip to aid placement.
• Clearly marked gastric and jejunal ports.

Sizes and options

• Outer diameter: 14, 16, 18, 22 Fr.
• Jejunal lengths: approximately 15, 22, 30, 45 cm (size-dependent).
• Stoma length options: approximately 1.0–7.0 cm, varying by tube diameter.

Materials and sterility

• Medical-grade silicone; latex-free.
• Sterile (gamma sterilized).
• Single-use; prescription device (Rx only).

Functional notes

• The gastric port is intended for decompression/drainage via gravity or low intermittent suction as clinically directed.
