Description
The Avanos MIC-KEY Low-Profile Gastric-Jejunal (GJ) Feeding Tube Kit with ENFit is a skin-level, double-lumen gastro-jejunostomy device placed through a gastric stoma, with the distal jejunal limb positioned in the small intestine. It supports simultaneous post-pyloric feeding and gastric decompression for pediatric and adult patients.
Intended Use
- Provides jejunal feeding while allowing gastric decompression/venting via a separate lumen.
- Low-profile, skin-level “button” design supports comfort, discretion, and mobility.
Design and Ports
- External low-profile button with external bolster and an internal inflatable silicone retention balloon.
- Three access points on the external bolster:
- JEJUNAL: for enteral feeding into the jejunum.
- GASTRIC: for decompression/venting (gravity or low intermittent suction per clinical direction).
- BAL: for balloon inflation/deflation.
- One-way valves in the JEJUNAL and GASTRIC ports open only when MIC-KEY extension sets are attached.
- No dedicated medication port; medications may be administered via the jejunal or gastric port per clinical direction.
Connectivity and Extension Sets
- ENFit connectivity (enteral-only standard).
- Compatible with MIC-KEY ENFit extension sets, including right-angle/continuous and bolus styles; closure caps and clamps included.
- SECUR-LOK low-profile connector interface between the button and extension sets.
Key Features
- Tungsten-weighted jejunal limb helps maintain placement; radiopaque stripe and weighted limb enhance imaging visibility.
- Multiple jejunal exit ports for distribution of feeds.
- Tapered distal tip to aid placement.
- Clearly marked gastric and jejunal ports for identification.
