Description

Overview

The Avanos MIC-KEY Low-Profile Gastric-Jejunal (GJ) Feeding Tube Kit (ENFit) is a skin-level, double-lumen device placed through a gastric stoma with the distal limb positioned in the jejunum. It enables simultaneous jejunal feeding and gastric decompression/venting for pediatric and adult patients. The low-profile “button” design sits at the skin surface for discretion and comfort and is supplied with compatible MIC-KEY ENFit extension sets for access.

Design and access ports

• Low-profile external bolster with an internal inflatable retention balloon
• Three clearly labeled access points on the button: JEJUNAL (feeding), GASTRIC (decompression/venting), BAL (balloon inflation/deflation)
• One-way valves in JEJUNAL and GASTRIC ports that open when MIC-KEY extension sets are attached
• No dedicated medication port; medications are administered via J or G port per clinical direction
• Gastric decompression via low intermittent suction or gravity drainage, as ordered

Connectivity and kit contents

• ENFit feeding connectors for standard enteral compatibility
• Kit includes MIC-KEY ENFit extension sets for continuous and/or bolus access
• SECUR-LOK mechanism helps secure extension sets to the button during use

Functional features

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

Materials, sterility, and regulatory

• Medical-grade silicone construction
• Not made with natural rubber latex
• Sterile (gamma sterilized)
• Single-use; prescription device (Rx only)

Sizes and configurations

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

Placement and use notes

• Intended for endoscopic or radiologic placement
• May be used for initial placement per clinical practice or as a replacement in a mature stoma tract
• For enteral feeding and gastric decompression/venting under clinician supervision; follow institutional protocols for care, verification of position, and maintenance
