Description

The Avanos MIC ENFit Gastrojejunal (GJ) Feeding Tube is a balloon‑retained, standard‑length, transgastric‑jejunal device with double lumens designed to support simultaneous jejunal feeding and gastric decompression/drainage in pediatric and adult patients who cannot adequately absorb via the stomach (e.g., intestinal dysmotility, gastric outlet obstruction, severe reflux/aspiration risk, post‑esophagectomy/gastrectomy). The jejunal port may also be used for medication delivery when clinically appropriate.

Key Features and Design

• Double‑lumen configuration with separate channels for gastric drainage and jejunal feeding
• Male ENFit connectors on both gastric and jejunal ports; clearly labeled; no separate medication port
• Internal silicone retention balloon; typical fill volume 7–10 mL (size‑dependent)
• SECUR‑LOK external retention ring for secure external fixation and stoma length adjustment
• Tapered distal tip with multiple jejunal exit ports to support distal delivery
• Radiopaque construction for imaging: tungsten‑weighted jejunal segment and barium‑sulfate radiopaque stripe on gastric segment
• Soft, medical‑grade silicone composition; not made with natural rubber latex, DEHP, DBP, or BBP
• Sterile, single‑use device; do not re‑use, re‑process, or re‑sterilize

Placement and Measurement

• Suitable for initial endoscopic or fluoroscopic placement and for replacement in an established stoma tract
• Jejunal length is measured from the distal aspect of the retention balloon to the catheter tip
• Radiopaque features assist with visualization during placement and verification

Sizes and Options (ENFit)

• 16 Fr outer diameter: jejunal lengths 15 cm, 22 cm, 30 cm, 45 cm
• 18 Fr outer diameter: jejunal lengths 22 cm, 30 cm, 45 cm
• 22 Fr outer diameter: jejunal length 45 cm

Included Components (typical kit)
