Description

The Avanos MIC-KEY Low-Profile Gastric-Jejunal (GJ) Feeding Tube is a skin-level, double-lumen device designed for pediatric and adult patients who require post-pyloric (jejunal) feeding with simultaneous gastric decompression or venting. It is placed through an existing gastric stoma, with the distal limb positioned in the jejunum, and features a low-profile, button-style head for discreet, skin-level access.

Intended Use

• Enables jejunal feeding while allowing concurrent gastric decompression/venting via separate lumens.
• Intended for use under clinical supervision in patients requiring post-pyloric nutrition.

Design and Ports

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

Connectivity

• ENFit connector standard (ISO 80369-3).
• Ports are accessed using MIC-KEY ENFit extension sets, with options for continuous or bolus feeding.

Key Features

• Tungsten-weighted jejunal section to help maintain position.
• Multiple jejunal exit ports for distribution of feeds.
• Radiopaque stripe for visibility under imaging.
• Tapered distal tip to aid placement.
• Low-profile, skin-level design with clearly marked gastric and jejunal ports.

Materials and Sterility

• Medical-grade silicone construction.
• Not made with natural rubber latex.
• Not made with DEHP, DBP, or BBP.
• Sterile (gamma sterilized); single-use; prescription device (Rx only).

Sizes and Options

• French sizes: 14, 16, 18, 22 Fr.
• Jejunal lengths: 15 cm, 22 cm, 30 cm, 45 cm (measured from the distal aspect of the retention balloon to the catheter tip).
• Stoma lengths: approximately 1.0–7.0 cm (availability varies by tube diameter).

Placement Considerations

• Suitable for endoscopic or radiologic placement.
• Weighted section and radiopaque stripe support verification and maintenance of position per institutional protocols.
• Use and maintenance should follow clinician judgment, product labeling, and facility guidelines.
