Description

The Avanos MIC-KEY Low-Profile Gastric-Jejunal (GJ) Feeding Tube Kit (ENFit) is a skin-level device for patients who require simultaneous post-pyloric (jejunal) feeding and gastric decompression/venting via separate lumens. Designed for pediatric and adult use, its low-profile “button” form factor supports patient comfort and allows the extension set to be detached when not in use. The kit includes MIC-KEY ENFit extension sets for port access.

Intended Use

• For pediatric and adult patients needing concurrent jejunal feeding and gastric decompression/venting through separate lumens.

Design Overview

• Low-profile, skin-level GJ tube placed through a gastric stoma with the distal limb positioned in the jejunum.
• Retained by an internal, water-inflated balloon and a low-profile external bolster.

Ports and Connectivity

• Two patient ports with internal one-way valves:
• JEJUNAL (feeding)
• GASTRIC (decompression/venting)
• Valves open when MIC-KEY ENFit extension sets are attached.
• Separate BAL port for inflation/deflation of the retention balloon.
• ENFit connector standard; kit includes MIC-KEY ENFit extension sets.

Key Features

• Weighted jejunal segment to help maintain distal position.
• Multiple jejunal exit ports to distribute enteral formula.
• Radiopaque stripe for X-ray visibility.
• Tapered distal tip to aid placement.
• Clearly marked G and J ports for identification.
• Low-profile design supports discretion and reduced snagging.

Materials and Sterility

• Medical-grade silicone construction.
• Latex-free.
• Sterile (gamma sterilized).
• Single-use device.

Sizes and Options

• French sizes: 14, 16, 18, 22.
• Jejunal limb lengths: 15 cm, 22 cm, 30 cm, 45 cm (size-dependent).
• Stoma length options: approximately 1.0–7.0 cm in various increments.

Compatibility and Usage Notes

• Uses MIC-KEY ENFit extension sets; extension sets from other brands are not interchangeable.
• Ports require an extension set to access; avoid overtightening when locking the extension.
• Do not rotate the device, as rotation can torque the tube and alter position.
• Inflate the retention balloon with sterile or distilled water only, per the Instructions for Use.
• No dedicated medication port; medications are administered via the G or J port as directed by the care team.
