MIC Bolus Gastrostomy Feeding Tube is used for patients on a bolus feeding regimen. It is made of medical-grade silicone for visibility and drapability, and it comes with an inflated silicone internal retention balloon. The Secur-Lok external retention ring is meant to let air circulate the stoma site and relieve tube pressure from both sides of the stoma wall.

Features

• Dual exit points.
• Radiopaque stripe.
• Available in seven French sizes.
• Medical-grade silicone structure.
• FDA-approved and CE-marked.
• Secur-Lok is an exterior retaining ring.
• An inflatable silicone internal retention balloon.
• Recessed distal tip with appropriate fill volume.
• Provides graduated centimeter markers for tube position verification.

Indications for Use

AVANOS MIC Gastrostomy / Bolus Feeding Tube is indicated for long-term feeding in patients who cannot eat orally, are at low aspiration risk, need gastric decompression, and/or require direct medication delivery into the stomach.

Contraindications

Include, but are not limited to:

• Ascites
• Colonic interposition
• Portal hypertension
• Peritonitis
• Morbid obesity

Possible Complications

• Infection
• Skin breakdown
• Pressure necrosis
• Intraperitoneal leakage
• Hypergranulation tissue
• Stomach or duodenal ulcers

Important Notes

• Do not use if the package is damaged or the sterile barrier is compromised.
• The tube is for enteral nutrition/medication only.

Placement Options

• Surgical
• Percutaneous (fluoroscopic or endoscopic guidance)
• Replacement via established stoma tract

Key Cautions & Warnings

• Gastropexy must be performed before initial placement.
• Never use the balloon as a gastropexy device (risk of rupture).
• In infants/children: place the insertion site high on the greater curvature to avoid pyloric occlusion when the balloon is inflated.

Balloon Maintenance (Check Weekly)

• Use Luer slip syringe → fully withdraw water → compare to prescribed volume.
• If low: refill with withdrawn water + add amount needed.
• Wait 10–20 min and recheck. If volume lost again → balloon leaking → replace tube.
• If the balloon ruptures/tube dislodges: tape in place and contact the physician immediately.
• Document date, time, volumes.
• ONLY use sterile/distilled water (never saline or air).
• Exact prescribed volume:
  • Over-inflation → lumen blockage or shorter balloon life
  • Under-inflation → poor fixation

Balloon Longevity

Silicone balloons typically last 1–8 months (varies with medications, water volume, gastric pH, and care).

Warning

Single-use device. DO NOT reuse, reprocess, or resterilize. Doing so may:

• Alter biocompatibility
• Compromise structural integrity
• Cause device failure
• Risk contamination/infection → patient injury, illness, or death
