Description

A skin-level, low-profile gastro-jejunal feeding solution, this MIC-KEY GJ tube is placed via a gastric stoma with the distal limb positioned in the jejunum. It enables simultaneous jejunal feeding and gastric decompression through separate lumens, supporting both pediatric and adult patients who require post-pyloric nutrition.

Intended Use

• For patients needing post-pyloric (jejunal) feeding with separate gastric access for decompression/venting.
• Supports concurrent jejunal feeding and gastric venting to manage tolerance and drainage needs.

Design and Ports

• Double-lumen, low-profile external button with an external bolster and internal inflatable silicone retention balloon.
• Three clearly labeled ports: JEJUNAL (feeding), GASTRIC (decompression/venting), BAL (balloon inflation/deflation).
• One-way valves in JEJUNAL and GASTRIC ports open when a MIC-KEY extension set is attached.
• No dedicated medication port; medications may be administered via the jejunal or gastric lumen per clinical direction.

Key Features

• ENFit feeding connections; MIC-KEY extension sets attach via SECUR-LOK connectors.
• Tungsten-weighted jejunal portion to help maintain position and provide radiopacity.
• Multiple gastric and jejunal exit ports for distribution and drainage.
• Radiopaque stripe to aid imaging and position verification.
• Tapered distal tip to assist with placement.
• Clearly marked ports and a discreet, low-profile button for comfort.

Materials and Safety

• Medical-grade silicone construction.
• Not made with natural rubber latex, DEHP, DBP, or BBP.
• Sterile (gamma sterilized); single-use; prescription device.

Sizes and Options

• French sizes: 14, 16, 18, 22 Fr.
• Jejunal lengths: 15, 22, 30, 45 cm (availability varies by diameter).
• Stoma length options: approximately 1.0–7.0 cm (availability varies by diameter/jejunal length).
• Jejunal length is measured from the distal aspect of the retention balloon to the catheter tip.
• Typical size dependencies: 22 Fr commonly with 45 cm jejunal length; 18 Fr with 22/30/45 cm; 14/16 Fr in select combinations including 15/22/30/45 cm.

Kit Contents

• MIC-KEY Low-Profile GJ tube (ENFit).
• MIC-KEY ENFit extension sets for continuous and bolus feeding.

Placement and Use Notes

• Designed for endoscopic or radiologic placement.
• Jejunal lumen is intended for feeding/fluids; gastric lumen is intended for decompression/venting.
• One-way valves in feeding and gastric ports engage upon connection with MIC-KEY extension sets.
