Description

Design and Indication

The Avanos MIC-KEY Low-Profile Gastric-Jejunal (GJ) Feeding Tube is a skin-level “button” enteral device placed through a gastric stoma with the distal limb positioned in the jejunum. It enables simultaneous jejunal feeding and gastric decompression/venting for pediatric and adult patients.

Placement and Retention

• Secured by an internal inflatable silicone balloon with a low-profile external bolster resting just above the skin.
• Suitable for endoscopic or radiologic placement and for replacement into a mature stoma.
• Jejunal length is measured from the distal aspect of the retention balloon to the catheter tip.

Ports and Flow

• Three labeled access points on the external bolster:
• JEJUNAL port: for feeding and medications per clinical direction.
• GASTRIC port: for decompression/venting and medications per clinical direction.
• BAL port: for balloon inflation/deflation.
• One-way/anti-reflux valves in the JEJUNAL and GASTRIC ports open when a MIC-KEY extension set is attached.
• No dedicated medication port.

Connectors and Accessories

• Available in ENFit and non-ENFit (catheter-tip) configurations, depending on model.
• Requires MIC-KEY GJ Extension Sets to access the JEJUNAL and GASTRIC ports; continuous/pump and bolus styles are available (approx. 12 in).
• Extension sets incorporate SECUR-LOK style connectors with orientation and locking features.

Key Design Features

• Low-profile button head with clearly marked ports.
• Tungsten-weighted jejunal limb to help maintain post-pyloric position; radiopaque stripe for imaging visibility.
• Multiple jejunal exit ports to distribute formula/distal flow.
• Tapered distal tip to aid placement.

Materials and Sterility

• Medical-grade silicone; not made with natural rubber latex.
• Not formulated with DEHP/DBP/BBP (per component materials specifications).
• Sterile, gamma-irradiated; single-use; prescription device (Rx only).

Sizes and Options

• Outer diameter (French): 14, 16, 18, 22 Fr.
• Stoma lengths: approximately 1.0 to 7.0 cm (availability varies by French size; offered in small increments).
• Jejunal lengths: 15, 22, 30, 45 cm (availability varies by configuration).

Balloon Fill Volumes

• For jejunal lengths 15, 22, or 30 cm: recommended 3 mL (maximum 5 mL).
• For jejunal length 45 cm: recommended 7 mL (maximum 10 mL).
• Use sterile or distilled water only; follow the Instructions for Use (IFU).

Kit Availability

Typical kit configurations may include: - MIC-KEY GJ Continuous Feed Extension Set (approx. 12 in). - MIC-KEY GJ Bolus Extension Set (approx. 12 in). - 35 mL syringe for priming/flushing (connector type varies by standard). - 6 mL Luer slip syringe for balloon inflation/deflation. - Patient use/care guide. (Stoma measuring device typically not included.)

Notes and Compatibility

• Designed to support simultaneous jejunal feeding and gastric decompression via gravity drainage or low intermittent suction per clinical guidance.
• Dimensions and option availability may vary within the stated ranges by configuration.
