Description

The MIC-KEY Low Profile Balloon Gastrostomy Feeding Tube is a specialized medical device designed for patients requiring long-term enteral feeding. Manufactured by Kimberly-Clark/Avanos Medical, it provides a discreet and comfortable solution for both children and adults who cannot tolerate oral feeding or need direct gastric access for nutrition, medication delivery, or decompression.

Key Features

• Low-Profile Design: This "button" tube sits at skin level, offering discretion and comfort.
• Material: Constructed from high-clarity, medical-grade silicone, it is biocompatible and latex-free.
• Retention Mechanism: An internal silicone balloon secures the tube within the stomach, inflated with sterile or distilled water.
• Connector Types: Available with Catheter Tip or ENFit connectors, compatible with MIC-KEY extension sets.
• Anti-Reflux Valve: Integrated in the feeding port to prevent backflow.
• Radiopaque Striping: Allows clear visualization during placement.
• Atraumatic Tip: Facilitates easy and comfortable insertion and removal.

Sizing and Configuration

The tube comes in various outer diameters ranging from 12 to 24 French, with stoma lengths from 0.8 cm to 5.0 cm. Balloon volumes are 3–5 mL, tailored to specific tube sizes. Kit contents may include extension sets, syringes, and a patient care guide.

Placement and Replacement

Placement can be performed percutaneously under fluoroscopic, laparoscopic, or endoscopic guidance. Replacement should be conducted by trained caregivers or clinicians, typically every 3–12 months.

Maintenance and Care

• Daily Cleaning: Clean the tube and stoma site with mild soap and water.
• Flushing: Regular flushing with water to prevent blockages.
• Balloon Maintenance: Weekly volume checks using sterile or distilled water.
• Extension Set Care: Replace extension sets regularly and ensure proper attachment.

Use Guidelines

Compatible with pump or gravity bolus feeds, the tube supports a range of dietary needs. Medication should preferably be in liquid form to prevent blockages. Normal activities, including bathing and swimming, are generally permissible after initial healing.

Troubleshooting and Complications

Common issues include site irritation, leakage, and clogged ports. Recommended troubleshooting includes adjusting balloon volume and ensuring proper flushing. Emergency preparedness involves having a spare tube readily available.

Contraindications

Conditions such as ascites, colonic interposition, and portal hypertension may contraindicate use. Proper adherence to clinical instructions is essential for safe and effective use.
