Description

The Avanos MIC-KEY Low-Profile Jejunal (J) Feeding Tube is designed for direct enteral delivery to the small intestine in patients who cannot tolerate or adequately absorb gastric feeding. This low-profile, button-style device provides discreet, secure access for continuous or bolus jejunal feeding and medication delivery under clinician direction.

Indications and Placement

• For feeding and medication administration into the distal duodenum/proximal jejunum (e.g., intestinal motility disorders, gastric outlet obstruction, severe GERD, aspiration risk, post-esophagectomy/gastrectomy).
• Percutaneous placement under fluoroscopic or endoscopic guidance, or as a replacement into an established stoma tract.

Design and Key Features

• Low-profile, button-style jejunostomy tube with a single access port labeled “Jejunal.”
• Non-ENFit connection; use a compatible catheter-tip extension set to access the port.
• Internal retention balloon and fixed external retention disc to help maintain position and reduce the risk of retrograde migration into the stomach.
• Trimmable distal tip to tailor intraluminal length to patient needs (by qualified clinicians per IFU).
• Radiopaque stripe for visibility under imaging.
• Medical-grade silicone construction for flexibility and biocompatibility.
• Sterile, gamma sterilized; prescription use only (Rx-only).

Specifications (18 Fr, 2.5 cm)

• Outer diameter: 18 Fr.
• Stoma (shaft) length: 2.5 cm.
• Jejunal length: 82 cm, measured from the distal aspect of the retention balloon to the tube tip.
• Access: Single jejunal port; no separate medication port.
• Connection type: Non-ENFit, catheter-tip compatible (extension set required).

Handling and Use Considerations

• Balloon: Inflate with sterile or distilled water only. Do not use saline, tap water, or air. Stabilize the tube during inflation/deflation and follow IFU/clinical guidance for fill volumes.
• Do not rotate jejunal or gastric-jejunal tubes; rotation can cause torquing and retraction into the stomach.
• Medications: Prefer liquid formulations. If tablets/capsules are appropriate to crush, mix with water; do not crush enteric-coated products. Flush with water before, between, and after medications. Avoid mixing medications with formula.
• Use a compatible catheter-tip extension set to access the non-ENFit port.
