Description
The Avanos MIC-KEY Low-Profile Gastric-Jejunal (GJ) Feeding Tube is a skin-level, button-style device that combines jejunal feeding and gastric decompression in a single unit. It is intended for pediatric and adult patients when simultaneous small-bowel nutrition and gastric venting or drainage are required.
Design and ports
- Retained by an internal inflatable silicone balloon with a low-profile external bolster.
- External head with three labeled ports:
- JEJUNAL (J): delivers feeds into the small intestine.
- GASTRIC (G): for gastric decompression/venting via gravity drainage or low intermittent suction.
- BAL: for balloon inflation/deflation.
- One-way valves in the J and G ports open only when a MIC-KEY extension set is attached.
Key features
- Low-profile, button design with clearly marked G and J ports.
- Weighted jejunal portion to support distal placement.
- Multiple jejunal exit ports to promote distal flow.
- Radiopaque stripe for imaging visibility.
- Tapered distal tip.
- Compatible with MIC-KEY extension sets; no dedicated medication port (medications may be administered via G or J port per clinical direction).
Connectivity and options
- Available with ENFit connectors or Catheter Tip (non-ENFit) connectors.
Sizes and configurations
- Outer diameter (French sizes): 14, 16, 18, 22 Fr.
- Jejunal lengths (availability varies by diameter): 15, 22, 30, 45 cm.
- Stoma lengths (availability varies by configuration): approximately 1.0–7.0 cm in listed increments (1.0, 1.2, 1.5, 1.7, 2.0, 2.3, 2.5, 2.7, 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, 6.0, 6.5, 7.0 cm).
Materials and regulatory
- Medical-grade silicone; latex-free.
- Sterile; gamma sterilized.
- Single-use; prescription device (Rx only).
Kits and compatibility
- Also available as MIC-KEY GJ Feeding Tube Kits. ENFit kit configurations include MIC-KEY ENFit extension sets (e.g., for continuous and/or bolus feeding).
Notes
- MIC-KEY extension sets are required to open the internal one-way valves for use.
- Dimensions and availability vary by configuration and may be updated within specifications.
