Description

Overview

The Avanos MIC-KEY Low-Profile Gastric-Jejunal (GJ) Feeding Tube is a skin-level, button-style enteral device placed via a gastric stoma with the distal limb positioned in the jejunum. It supports post-pyloric feeding while enabling simultaneous gastric decompression or venting through a separate lumen. For pediatric and adult patients; prescription device.

Design and Materials

• Internal retention balloon with a low-profile external bolster for stabilization
• Medical-grade silicone construction; latex-free
• Sterile (gamma sterilized); single-use
• Low-profile head designed for discreet wear and secure connection

Ports and Connectivity

• Three access points on the head:
• JEJUNAL port (feeding)
• GASTRIC port (decompression/venting)
• BAL port (balloon inflation/deflation)
• One-way valves in JEJUNAL and GASTRIC ports; valves open only when the appropriate MIC-KEY extension set is attached
• No dedicated medication port; medications are delivered via J or G port per clinical direction
• Available with ENFit connectors; also offered in versions with catheter-tip (non-ENFit) connectors
• Low-profile GJ tubes require an extension set to open the valves for delivery of feeds, liquids, and medications
• ENFit kits include MIC-KEY ENFit extension sets for continuous/pump and bolus feeding (refer to IFU for specific components)

Key Functional Features

• Weighted jejunal portion to help maintain position
• Multiple jejunal exit ports for distribution
• Radiopaque stripe for imaging visibility
• Tapered distal tip to aid placement
• Clearly marked G and J ports

Sizes and Options

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

Use and Handling Guidance (refer to current IFU)

• Balloon: Inflate with distilled or sterile water only; do not use saline, tap water, or air. Verify balloon volume periodically per IFU and tube size. Stabilize the tube during inflation/deflation to avoid dislodgement.
• Positioning: Keep head/torso elevated at least 30 degrees during feeds and for about 1 hour after.
• Rotation: Do not rotate jejunal or gastric-jejunal tubes to prevent torque or retraction into the stomach.
• Medications: Prefer liquid formulations. If tablets are used, confirm they can be crushed; mix only with water and flush with water before and between medications. Do not crush enteric‑coated medications.
• Decompression: Use the gastric port for venting via gravity or low intermittent suction. Avoid continuous or high suction. Attach the appropriate extension set to open the valve; do not inject formula or medications into a closed valve.

Accessory Compatibility

• Compatible with the FARRELL Decompression System for venting excess gas while allowing feeds to return by gravity; use per device IFUs.

Important Notes

• Dimensions and specific options vary; always confirm selection and instructions in the current Avanos IFU.
• For pediatric and adult use as prescribed by a clinician.
