Description
The Avanos MIC-KEY Low-Profile Gastric-Jejunal (GJ) Feeding Tube Kit (ENFit) is a skin-level enteral access device placed through a gastric stoma with the distal limb positioned in the jejunum. It enables post-pyloric (jejunal) feeding while allowing simultaneous gastric decompression or venting via a separate lumen. Appropriate for pediatric and adult patients as directed by a clinician.
Design and ports
- Low-profile external bolster with an internal inflatable retention balloon.
- Three external access points: JEJUNAL (feeding), GASTRIC (decompression/venting), BAL (balloon inflation/deflation).
- One-way valves in the JEJUNAL and GASTRIC ports open when a MIC-KEY extension set is attached.
- No dedicated medication port; medications are administered through the jejunal or gastric port per clinical direction.
Key features
- Clearly marked and separate G and J lumens to support simultaneous functions.
- Weighted jejunal segment to help maintain jejunal placement.
- Multiple jejunal exit ports for distribution of feeds.
- Radiopaque stripe for imaging visibility.
- Tapered distal tip to aid placement.
- Low-profile, skin-level “button” design for comfort and discretion.
Connectivity and included components
- ENFit connector standard for enteral-only connections.
- Kit includes MIC-KEY ENFit extension sets (continuous and/or bolus types, per kit configuration).
Materials and sterility
- Medical-grade silicone; latex-free.
- Sterile (gamma sterilized); single-use.
Sizes and options
- French sizes: 14 Fr, 16 Fr, 18 Fr, 22 Fr.
- Jejunal lengths (size-dependent): 15 cm, 22 cm, 30 cm, 45 cm.
- Stoma length options (approximate): 1.0–7.0 cm; availability varies by tube diameter.
Compatibility and use considerations
- Designed for use with MIC-KEY ENFit extension sets provided in the kit.
- Prescription device (Rx only); use per institutional protocols and clinician direction.
- Placement and patency should be confirmed per clinical practice; radiopaque stripe assists with imaging verification.
