Description

The MIC-KEY Low Profile Balloon Gastrostomy Feeding Tube is an essential medical device designed for patients requiring long-term enteral feeding, gastric decompression, or direct medication delivery into the stomach. Its discreet, low-profile design sits at skin level, often referred to as a "button" tube, reducing visibility and minimizing the risk of accidental removal.

Key Features

• Secure Placement: The tube is held in place by an internal silicone balloon, which is filled with sterile or distilled water. This ensures secure positioning within the stomach while the external base rests slightly above the skin to allow air circulation.

• Anti-Reflux Valve: Equipped with a feeding and medication port that includes an anti-reflux valve, the tube prevents leakage of stomach contents when not in use. The port is accessed using a lock-and-key style extension set, known as the SECUR-LOK connector.

• Connector Options: Available with ENFit or Catheter Tip connectors, and some models include a medication port. A radiopaque stripe enhances visibility under imaging.

• Material and Safety: Made from medical-grade silicone, the tube is latex-free, DEHP-free, and not made with natural rubber. It is a sterile, single-use device, safe for MRI environments under specified conditions.

Sizes and Configurations

The tube comes in various French sizes ranging from 12 Fr to 24 Fr, with stoma lengths from 0.8 cm to 5.0 cm. Balloon fill volumes vary by size, with specific recommendations to ensure optimal performance.

Placement and Maintenance

Placement can be performed percutaneously under fluoroscopic, laparoscopic, or endoscopic guidance, or as a replacement using an established stoma tract. Replacement is typically needed every 3–6 months and can be managed by trained clinicians or caregivers.

Daily care involves cleaning the tube and stoma site, rotating the tube to prevent sticking, and flushing with warm water before and after feedings. Balloon volume should be checked regularly, and extension sets should be cleaned and replaced periodically.

Accessories

Accessory kits may include extension sets, syringes for balloon management, gauze pads, and a patient use and care guide. These components support effective use and maintenance of the device.

Use Cases and Precautions

The MIC-KEY tube is suitable for various feeding methods and medication administration, compatible with feeding pumps or gravity feeding sets. It is contraindicated in patients with certain gastric conditions, and proper care must be taken to verify tube position and package integrity before use.

This device is designed to minimize complications when properly maintained, providing a reliable solution for both pediatric and adult patients in need of specialized nutritional support.
