Description

Overview

The MIC-KEY Low-Profile Gastric-Jejunal (GJ) Feeding Tube is a skin-level, dual-lumen gastrojejunostomy device that provides jejunal access for feeding and gastric access for decompression/venting. The JEJUNAL port is typically the primary route for nutrition delivery and may be used for medications when directed. The GASTRIC port supports decompression/venting and may also be used for medications per clinical guidance.

Design and Ports

• Low-profile “button” head/bolster with an internal inflatable silicone retention balloon
• Three clearly labeled access points: JEJUNAL (feeds), GASTRIC (decompression/venting), and BAL (balloon inflation/deflation)
• One-way valves in JEJUNAL and GASTRIC ports that open only when a compatible MIC-KEY extension set is attached
• No dedicated medication port; medications are administered via J or G port as ordered
• Tungsten-weighted jejunal limb to help maintain jejunal position
• Radiopaque stripe for imaging, multiple jejunal exit ports for distribution, and a tapered distal tip to aid placement

Connectivity and Kit Configuration

• Available in ENFit and non-ENFit versions
• ENFit versions connect via included MIC-KEY ENFit extension sets (options for continuous or bolus feeding)
• Non-ENFit versions use catheter tip-style connectors via extension sets
• Button ports interface only with MIC-KEY extension sets to actuate the internal valves

Compatibility

• Compatible with the FARRELL Decompression System for gastric venting

Materials and Sterility

• Medical-grade silicone construction
• Not made with natural rubber latex; not formulated with DEHP/DBP/BBP
• Sterile (gamma sterilized); single-use only (do not re-use, reprocess, or re-sterilize)

Sizes and Selection

• French sizes: 14 Fr, 16 Fr, 18 Fr, 22 Fr
• Jejunal lengths: 15 cm, 22 cm, 30 cm, 45 cm (availability varies by diameter)
• Stoma lengths: approximately 1.0–7.0 cm (typical minima: 14/16 Fr 1.0 cm; 18 Fr 1.2 cm; 22 Fr 1.5 cm)
• Sizing is by French diameter and stoma length; jejunal length is measured from the distal aspect of the balloon to the catheter tip

Placement and Replacement

• Inserted through a gastric stoma with the distal limb positioned in the jejunum
• Typically placed or replaced under endoscopic or fluoroscopic guidance; bedside replacement of GJ tubes is not recommended

Handling and Safety Notes

• Inflate the retention balloon only with sterile or distilled water; do not use saline, tap water, or air
• Verify and maintain balloon volume per the device IFU; stabilize the tube during checks to avoid dislodgement
• Do not rotate jejunal or gastric-jejunal tubes
• Use the gastric port for decompression/venting as ordered; deliver feeds via the jejunal port unless otherwise directed

Regulatory Information

• Prescription device (Rx only)
• CE-marked medical device; manufacturer quality system certified
