Description
The Avanos MIC ENFit Gastrojejunal (GJ) Feeding Tube is a balloon‑retained, transgastric–jejunal device designed to deliver enteral nutrition and medications to the jejunum while allowing simultaneous gastric decompression/venting. It is indicated for patients who cannot adequately absorb nutrition via the stomach, including those with intestinal dysmotility, gastric outlet obstruction, severe reflux or aspiration risk, or post‑esophagectomy/gastrectomy.
Key features and design
- Double‑lumen configuration with separate gastric drainage and jejunal feeding channels
- ENFit connectors: male ENFit on both gastric and jejunal ports; no separate medication port
- Internal silicone retention balloon; recommended fill volume 7–10 mL (size‑dependent)
- SECUR‑LOK external retention ring for stabilization and stoma depth control
- Tapered distal tip; multiple side exit ports on gastric and jejunal limbs
- Radiopaque construction with weighted jejunal segment and radiopaque stripe for imaging
- Medical‑grade silicone; not made with natural rubber latex; DEHP‑free
Sizes and options (ENFit versions)
- Outer diameter (French): 16 Fr, 18 Fr, 22 Fr
- Jejunal limb lengths (measured from distal aspect of the balloon to catheter tip):
- 16 Fr: 15, 22, 30, 45 cm
- 18 Fr: 22, 30, 45 cm
- 22 Fr: 45 cm
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
- Fill balloon with sterile water to the size‑specific recommended volume; verify position per institutional protocol and imaging as needed
