Description

The MIC-KEY Low Profile Balloon Gastrostomy Feeding Tube, developed by Avanos, is a specialized medical device designed for patients requiring long-term enteral nutrition, fluid, and medication delivery directly into the stomach. This device is particularly beneficial for individuals across all age groups, including neonates, children, and adults, who are unable to tolerate oral feeding, are at low risk for aspiration, or need gastric decompression.

Key Features

• Low-Profile Design: The tube sits flush against the skin, offering comfort and discretion while minimizing the risk of accidental dislodgement.
• Internal Retention Balloon: Secures the tube within the stomach using sterile or distilled water.
• Radiopaque Stripe: Enhances visibility under fluoroscopic imaging for accurate placement.
• Anti-Reflux Valve: Prevents backflow of gastric contents when the tube is not in use.
• Recessed, Tapered Distal Tip: Reduces irritation to the stomach wall and allows for smooth insertion and removal.
• External Bolster: Provides stability, reduces movement, and supports stoma development.

Construction and Compatibility

Crafted from latex-free, medical-grade silicone, the MIC-KEY G-Tube is biocompatible and suitable for patients with latex allergies. It features a universal ENFit connector, with options for ENFit or Catheter Tip connectors, ensuring compatibility with various enteral feeding systems. Some models also include a dedicated medication port.

Available Configurations

The tube is available in multiple outer diameters ranging from 12 to 24 French, with stoma lengths from 0.8 cm to 5.0 cm. Balloon volumes vary by tube size, typically between 3–10 mL. Each configuration is designed to meet specific patient needs, providing flexibility in clinical application.

Kit Components

The product kit includes extension sets for continuous and bolus feeding, syringes for balloon management and feeding, and additional components such as a gauze pad and patient care guide. Some kits may also include a stoma measuring device and insertion stylet.

Indications and Placement

Suitable for both primary and established stomas, the MIC-KEY G-Tube can be placed percutaneously under fluoroscopic, laparoscopic, or endoscopic guidance. It can also be replaced through an established stoma tract, offering versatility in clinical settings.

Maintenance and Care

Proper maintenance involves daily cleaning of the tube and stoma site, regular rotation of the tube to prevent tissue overgrowth, and periodic checking of the balloon. Extension sets should be replaced regularly, and the tube should be flushed before and after use to prevent clogging. Medication administration should be managed carefully to avoid blockages.

Contraindications

The device is contraindicated in patients with conditions such as ascites, colonic interposition, portal hypertension, peritonitis, and morbid obesity. It is intended for single use only and should not be reused or reprocessed.

Additional Considerations

The external base of the tube should rest slightly above the skin, and the tube is marked at 1 cm increments for monitoring placement. Extension sets are not interchangeable with other brands, and product characteristics may change as part of continuous improvement efforts.
