Abstract

A balloon-type gastric band includes a balloon shaped and dimensioned to circumscribe the stomach at a predetermined location. The balloon includes a longitudinally extending body. A supply tube is secured to the balloon for fluid communication with an internal cavity of the balloon, wherein the supply tube includes a valve controlling the flow of fluid to and from the balloon.

Claims

1. A balloon-type gastric band, comprising:

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

the balloon includes a longitudinally extending body;

a supply tube secured to the balloon for fluid communication with an internal cavity of the balloon, wherein the supply tube includes a valve controlling the flow of fluid to and from the balloon.

2. The balloon-type gastric band according to claim 1, wherein the valve is a check valve.

3. The balloon-type gastric band according to claim 2, wherein the check valve is a ball check valve.

4. The balloon-type gastric band according to claim 3, wherein the ball check valve is spring biased.

5. The balloon-type gastric band according to claim 1, further including a fluid injection port shaped and dimensioned for selective attachment to the balloon for fluid communication therewith.

6. The balloon-type gastric band according to claim 5, wherein the valve may be removed from the supply tube prior to attachment of the supply tube to the fluid injection port.

7. The balloon-type gastric band according to claim 5, wherein the fluid injection port is shaped and dimensioned for selective attachment to the valve.

8. The balloon-type gastric band according to claim 7, wherein the fluid injection port includes a central barb selectively engaging the valve for opening the check valve for the flow of fluid from the fluid injection port to the balloon.

9. The balloon-type gastric band according to claim 8, wherein the valve is spring biased.

10. The balloon-type gastric band according to claim 8, wherein the valve is a spring biased, ball check valve and the central barb selectively engages the ball to open the valve for the flow of fluid from the fluid injection port to the balloon.

11. A supply tube for a balloon-type gastric band including a balloon shaped and dimensioned to circumscribe the stomach at a predetermined location, comprising:

a supply tube adapted for attachment to the balloon of the gastric band for fluid communication with an internal cavity of the balloon, wherein the supply tube includes a valve controlling the flow of fluid to and from the balloon;

a fluid injection port shaped and dimensioned for selective attachment to the supply tube for providing a fluid source.

12. The supply tube according to claim 11, wherein the valve is a check valve.

13. The supply tube according to claim 12, wherein the check valve is a ball check valve.

14. The supply tube according to claim 13, wherein the ball check valve is spring biased.

15. The supply tube according to claim 11, wherein the valve may be removed from the supply tube prior to attachment of the supply tube to the fluid injection port.

16. The supply tube according to claim 11, wherein the fluid injection port is shaped and dimensioned for selective attachment to the valve.

17. The supply tube according to claim 16, wherein the fluid injection port includes a central barb selectively engaging the valve for opening the check valve for the flow of fluid from the fluid injection port to the balloon.

18. The supply tube according to claim 17, wherein the valve is spring biased.

19. The supply tube according to claim 17, wherein the valve is a spring biased, ball check valve and the central barb selectively engages the ball to open the valve for the flow of fluid from the fluid injection port to the balloon.
