The word Lap-Band® is the abbreviated and trademarked combination of two words (LAP from laparoscopic and BAND from gastric band).

The Lap-Band System's silicone elastomer band is placed around the upper part of the stomach to create a small stomach pouch which can hold only a small amount of food. The lower, larger part of the stomach is below the band.

These two parts are connected by a small outlet created by the band. Food will pass through the outlet ("stoma" in medical terms) from the upper stomach pouch to the lower part more slowly, and you will feel full longer.

One of the major advantages of the LAP-BAND System is that the diameter of the band outlet is adjustable to meet your individual needs, which can change as you lose weight. The inner surface of the band can be inflated with liquid (saline solution) or deflated to modify the size of the stoma. The band is connected by tubing to a reservoir, which is placed well under the skin during surgery.

After the operation, the surgeon can control the amount of saline in the band by entering the reservoir with a fine needle through the skin.

The LAP-BAND System is a unique surgical treatment because in many cases the size of the stoma can be customized to accommodate your changing needs without further surgery.

The LAP-BAND Adjustable Gastric Banding (LAGB®) System is designed to induce weight loss in severely obese patients by limiting food consumption.

The slip-through buckle design band eases laparoscopic placement around the stomach and forms a small gastric pouch and stoma. No cutting or stapling of the stomach is required and there is no by-passing of portions of the stomach or intestines.

The initial pouch and stoma sizes are controlled through the use of the calibration tube. (An inflation of the calibration tube balloon with 15-25 cc of air or saline provides an acceptable size range of the proximal pouch.

The precise size may vary among patients depending on dissection points, individual patient physiology, and balloon and placement procedures.) The inner surface of the band is inflatable and connected by kink-resistant tubing to the access port, which is included in the LAGB System.

This permits postoperative percutaneous stoma size adjustment. Dietary and behavior modification counseling, and frequent and long term follow-up are required for all patients after weight-loss surgery.

The LAGB is a 13 mm-wide band which, when fastened, forms a circular ring with an inside circumference of 9.75 cm or 10 cm and transitions to a 50 cm-long silicone tube.

The band is made of silicone elastomer, chosen for its biocompatibility and inertness. The inner surface of the band is inflatable. The radiopaque kink-resistant tube is used to connect the inflatable section to the access port. An end plug is provided to seal the system while the band is being passed around the stomach.

Access Port Features The access port is for percutaneous adjustment of the stoma diameter and is self-sealing when penetrated by the access-port needle. Other features include: high compression septum; tested to over 1,000 punctures with a 20 gauge non-coring needle. Titanium reservoir: designed for long-tern durability and positive tactile feedback when accessing needle makes contact; resists gouging from repeated needle contact for long-term reservoir integrity.
