Gastric Inflation Band with Integrated Infusion Catheter
First Claim
1. A gastric band for treating obesity, the gastric band comprising:
- a band portion having an outer inextensible member and an inner inflation bladder, the outer inextensible member including a channel having at least one opening;
an infusion port having a first chamber and a second chamber; and
a catheter portion having a first end attached to the band portion and a second end attached to the infusion port, the catheter portion including;
a first lumen in fluid communication with the inner inflation bladder and the first chamber of the infusion port, thereby allowing liquids introduced into the first chamber to expand the inner inflation bladder; and
a second lumen in fluid communication with the channel of the inextensible member and the second chamber of the infusion port, thereby allowing liquids introduced into the second chamber to pass into an abdominal cavity of a gastric band recipient via the at least one opening.

Abstract
An inflatable gastric band incorporates a fluid channel within an outer surface of the band and an inflatable bladder on a stomach-facing side of the band. The gastric band attaches to a double lumen catheter, which communicates with a dual infusion port. One lumen communicates with the fluid channel and one port, while the other lumen communicates with the inflatable bladder and a second port. Injection of fluid into one chamber of the infusion port expands inflatable bladder, allowing adjustment to the diameter of the stoma. Injection of drugs or therapeutic agents into the second chamber allows the infusion of drugs or agents directly into the abdominal cavity of a gastric band recipient. The inflatable bladder can be continuous or segmented. A segmented bladder reduces pinching and/or folding of the inner surface of the gastric band during expansion/contraction, thereby lessening stomach pinching and/or irritation.
