Description
Overview
The Avanos Medical MIC-KEY Low-Profile Jejunal (J) Feeding Tube is a button-style, low-profile device designed to deliver enteral nutrition, liquids, and medications directly to the distal duodenum/proximal jejunum. It sits close to the skin with a fixed external retention disc/bolster and an internal retention balloon to help maintain position while minimizing profile at the stoma site.
Indications/Intended Use
Intended for patients who require jejunal feeding and cannot tolerate gastric feeding or have impaired gastric emptying, severe GERD, gastric outlet obstruction, elevated aspiration risk, or a history of esophagectomy/gastrectomy. Prescription use (Rx only).
Design and Key Features
- Low-profile “button” configuration for discreet wear and reduced snagging
- Internal retention balloon with fixed external retention disc/bolster
- Medical-grade silicone construction
- Valved access that requires a detachable extension set to administer feeds and medications
- Single access port labeled “Jejunal”; no separate medication port
- Connector variants: ENFit or non-ENFit (Catheter Tip)
- SECUR-LOK mechanism on compatible MIC-KEY extension sets
- Radiopaque stripe to aid visualization under imaging
- Centimeter markings for external length verification
- Trimmable distal tip to tailor distal length per clinical judgment
Sizes and Options
- Outer diameter: 14 Fr or 18 Fr
- Jejunal length: 82 cm (measured from the distal aspect of the internal retention balloon to the tube tip)
- Stoma length options (cm): 0.8, 1.0, 1.2, 1.5, 1.7, 2.0, 2.3, 2.5, 2.7, 3.0, 3.5, 4.0, 4.5
- Compatible MIC-KEY extension sets available in continuous or bolus styles (match connector type to device variant)
Placement and Replacement
May be placed percutaneously under fluoroscopic or endoscopic guidance, surgically, or used as a replacement through an established stoma tract per the manufacturer’s instructions for use. Centimeter markings support external length checks. Radiographic confirmation and institutional protocols should guide verification of jejunal placement.
Sterility and Regulatory
Sterile; gamma sterilized. Rx only.
