Description

The Avanos MIC-KEY Low-Profile Gastric-Jejunal (GJ) Feeding Tube Kit (ENFit) is a skin-level, double-lumen gastro-jejunostomy device designed to provide post-pyloric (jejunal) feeding while allowing simultaneous gastric decompression/venting. The distal limb resides in the jejunum, and the low-profile, “button” design supports comfort and discretion for pediatric and adult patients.

Intended use / Indications

• Enables jejunal feeding with a separate gastric lumen for decompression/venting.
• Common clinical scenarios: impaired gastric emptying or motility, aspiration risk, gastric outlet obstruction, severe GERD, or post-esophagectomy/gastrectomy when post-pyloric feeding with gastric drainage is required.

Design and ports

• Low-profile head with external bolster and an internal inflatable retention balloon.
• Three access points: JEJUNAL (feeding), GASTRIC (decompression/venting), and BAL (balloon inflation/deflation).
• JEJUNAL and GASTRIC ports feature one-way valves that open when MIC-KEY extension sets are connected.
• No dedicated medication port; medications may be administered via the jejunal or gastric lumen per clinical direction.

Key features

• Weighted jejunal segment to help maintain distal placement.
• Multiple jejunal exit ports for distributed flow.
• Radiopaque stripe/markings for imaging visibility; clearly labeled gastric and jejunal ports on the head.
• Tapered distal tip to aid placement.
• Medical-grade silicone construction; skin-level profile for comfort.

Connectivity and kit contents (ENFit)

• ENFit connectivity on the feeding set side; MIC-KEY extension sets mechanically lock to open the one-way valves.
• Typical kit components: MIC-KEY GJ tube; ENFit Continuous/Pump Extension Set (~12 in/30 cm); ENFit Bolus Extension Set (~12 in/30 cm); 35 mL ENFit syringe; 6 mL luer-slip syringe (balloon); patient care information; gauze pads.

Sizes and configurations

• French sizes: 14, 16, 18, 22 Fr.
• Jejunal lengths: 15, 22, 30, 45 cm (availability varies by configuration).
• Stoma lengths: approximately 1.0–7.0 cm in defined increments (availability varies by French size).
• Connector variants in the family include ENFit and non-ENFit; this kit is the ENFit version.
• Measurement note: jejunal length is measured from the distal aspect of the retention balloon to the catheter tip.

Balloon specifications

• Recommended fill volumes generally correlate with jejunal length: 3 mL (max 5 mL) for 15–30 cm J lengths; 7 mL (max 10 mL) for 45 cm J length. Refer to the device IFU for the specific tube’s recommended volume.

Materials, sterility, and use

• Medical-grade silicone; not made with natural rubber latex; not made with DEHP/DBP/BBP.
• Sterile (gamma sterilized); single-use; prescription only (Rx-only).

Regulatory and quality

• CE marked; sterilized by gamma radiation; manufacturer quality system compliant with ISO 13485.

Storage and shelf life

• Store in a cool, dry place away from heat and radiation.
• Typical shelf life: 2 years from date of manufacture.

Additional notes

• Initial placement may be performed endoscopically or radiologically per clinical practice. An introducer set may be used for initial placement but is not included in the standard ENFit kit.
