Description

The Avanos MIC-KEY Low-Profile Gastric-Jejunal (GJ) Feeding Tube Kit with ENFit extension sets is a skin-level enteral access device for pediatric and adult patients requiring simultaneous jejunal feeding and gastric decompression/venting. It is placed through a gastric stoma with the distal limb positioned in the jejunum, combining a low-profile external bolster with an internal inflatable retention balloon.

Key Features

• Weighted jejunal segment to help maintain placement in the jejunum.
• Multiple jejunal exit ports support distribution of enteral formula.
• Radiopaque stripe for visualization and position verification under imaging.
• Tapered distal tip to aid advancement and placement.
• Low-profile, skin-level design to support patient comfort and discretion.

Ports and Connectivity

• Three access points: JEJUNAL (feeding), GASTRIC (decompression/venting), and BAL (balloon inflation/deflation).
• JEJUNAL and GASTRIC ports contain one-way valves that open when a MIC-KEY ENFit extension set is attached; ports are clearly marked J and G.
• ENFit enteral-only connectivity helps reduce misconnections; kit includes ENFit extension sets.
• No dedicated medication port; administer medications via the J or G port per clinical direction.

Sizes and Options

• French sizes: 14, 16, 18, 22 Fr.
• Jejunal lengths: 15, 22, 30, 45 cm (availability varies by French size).
• Stoma tract lengths: approximately 1.0–7.0 cm in defined increments (availability varies by French size).

Balloon and Retention

• Internal balloon provides retention; fill via the BAL port using sterile or distilled water.
• Recommended balloon fill volumes by jejunal length:
• 15–30 cm: 3 mL (maximum 5 mL)
• 45 cm: 7 mL (maximum 10 mL)

Materials and Sterility

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

Kit Contents and Compatibility

• Compatible with MIC-KEY GJ ENFit extension sets; kit includes ENFit extension sets for continuous/pump feeding and bolus feeding.
• Some kits include a 35 mL syringe (for venting/priming/flushing) and a 6 mL luer slip syringe (for balloon inflation).
• Stoma measuring device not included.

Use Guidance

• For gastric decompression, use gravity drainage or low intermittent suction; do not use continuous or high intermittent suction.
• Medications should be administered via the J or G port as directed by the care team.
• Also available as a legacy, non-ENFit connector version (separate from this ENFit kit).
