Abstract

A gastric band includes a belt and a balloon secured to the belt. The balloon and belt are shaped and dimensioned to circumscribe the stomach at a predetermined location. The balloon includes a longitudinally extending body having a first end and a second end, the first end and the second end respectively including mating profiles which align to create generally continuous surfaces along an outer surface of the gastric band and an inner surface of the gastric band as the outer surface and the inner surface transition between the first and second ends of the balloon.

Claims

1. A gastric band, comprising:

a balloon shaped and dimensioned to circumscribe the stomach at a predetermined location;

the balloon includes a longitudinally extending body having a first end and second end, the first end and the second end respectively including mating profiles which align to create a generally continuous surface along an inner surface of the gastric band as the inner surface transitions between the first and second ends of the balloon; and

wherein the first and second ends are respectively formed with tongue and groove profiles which mate when the first and second ends are brought together.

2. The gastric band according to claim 1, further including a fluid supply tube fluidly communicating with the balloon for controlled inflation thereof.

3. The gastric band according to claim 2, further including a fluid injection port in fluid communication with the fluid supply tube.

4. The gastric band according to claim 1, wherein the balloon is composed of silicone.

5. The gastric band according to claim 4, further including a belt, and wherein the balloon is affixed to an inner surface of the belt.

6. The gastric band according to claim 5, wherein the balloon and belt are composed of silicone.

7. The gastric band according to claim 1, further including a fastening mechanism for selectively securing the gastric band in an encircled position around a portion of the stomach.

8. A gastric band, comprising:

a belt including a first end and a second end, the first end of the belt and the second end of the belt including respective mating fastening members for selectively securing the gastric band in an encircled position around a portion of the stomach;

a balloon secured to the belt, the balloon and belt being shaped and dimensioned to circumscribe the stomach at a predetermined location;

the balloon includes a longitudinally extending body having a first end and second end, the first end of the balloon and the second end of the balloon respectively including mating profiles which align to create a generally continuous surface along an inner surface of the gastric band as the inner surface transitions between the first and second ends of the balloon;

wherein the first and second ends of the balloon are respectively formed with angled surfaces which mate when the first and second ends of the balloon are brought together.

9. A gastric band, comprising:

a belt including a first end and a second end, the first end of the belt and the second end of the belt including respective mating fastening members for selectively securing the gastric band in an encircled position around a portion of the stomach;

a balloon shaped and dimensioned to circumscribe the stomach at a predetermined location;

the balloon includes a longitudinally extending body having a first end and second end, the first end of the balloon and the second end of the balloon respectively including mating profiles which align to create a generally continuous surface along an inner surface of the gastric band as the inner surface transitions between the first and second ends of the balloon; and

wherein the first and second ends of the balloon are respectively formed with angled surfaces which mate when the first and second ends of the balloon are brought together.
