System Overview

In this procedure, a hollow band made of special material is placed around the stomach near its upper end, creating a small pouch and a narrow passage into the larger remainder of the stomach. The band is then inflated with a salt solution. It can be tightened or loosened over time to change the size of the passage by increasing or decreasing the amount of salt solution. The entire procedure is done laparoscopically, where a laparoscope is inserted through the abdominal wall through small surgical incisions.

It induces weight loss by reducing the capacity of the stomach, which restricts the amount of food that can be consumed.

Minimal Trauma

• Least invasive surgical option
• No intestinal re-routing
• No cutting or stapling of the stomach wall or bowel
• Reduced pain, hospital length-of-stay, and recovery period

Fewer Risks and Side Effects

• Lower mortality risk than other obesity surgery procedures
• Low risk of nutritional deficiencies associated with gastric bypass
• Reduced risk of hair loss
• No “dumping syndrome” related to dietary intake restrictions


• Allows individualized degree of restriction for ideal, long-term weight loss
• Adjustments performed without additional surgery
• Supports pregnancy by allowing stomach outlet size to be opened for increased nutritional needs


• Removable
• Stomach and other anatomy are generally restored to their original forms and functions

Effective Long-Term Weight Loss

• More than 600,000 cases performed worldwide
• Average of 40-60% of excess body weight @ 2 years

To modify the size of the band, its inner surface can be inflated or deflated with a saline solution. The band is connected by tubing to an access port, which is placed well below the skin during surgery. After the operation, the surgeon can control the amount of saline in the band by entering the port with a fine needle through the skin.
