Abstract

A gastric tube for use in a bariatric surgical procedure includes an elongate tube and a movable component supported on an outer surface of the elongate tube. The elongate tube has a non-circular cross section along at least a portion of a length of the elongate tube. The movable component is movable between an unexpanded configuration and an expanded configuration. In the unexpanded configuration, the movable component is disposed in abutting engagement with the outer surface of the elongate tube. In the expanded configuration, the movable component bows outwardly from the outer surface of the elongate tube.

First claim

What is claimed is:

1. A gastric tube for use in a bariatric surgical procedure, comprising:
an elongate tube including an outer surface defining a groove in the outer surface, the groove extending along a length of the elongate tube and including:
a proximal portion extending along a proximal end portion of the elongate tube and having a first dimension; and
a distal portion extending along a distal end portion of the elongate tube and having a second dimension, different than the first dimension of the proximal portion; and

a movable component supported in the groove of the elongate tube and movable between an unexpanded configuration in which the movable component is disposed within the groove and an expanded configuration in which at least a portion of the movable component extends outwardly from the outer surface of the elongate tube, wherein the movable component has a distal end that is fixedly coupled to the distal end portion of the elongate tube.

2. The gastric tube as recited in claim 1 , wherein the movable component has a distal portion releasably disposed within the distal portion of the groove such that the distal portion of the movable component is disposed outside of the distal portion of the groove when the movable component moves toward the expanded configuration.

3. The gastric tube as recited in claim 1 , wherein the proximal portion of the groove is configured to retain a proximal portion of the movable component, and the distal portion of the groove is configured to permit a distal portion of the movable component to move out of the distal portion of the groove when the movable component moves toward the expanded configuration.

4. The gastric tube as recited in claim 3 , wherein the proximal portion of the groove is omega-shaped and the distal portion of the groove has a concave configuration.

5. The gastric tube as recited in claim 3 , wherein the proximal portion of the movable component is slidably captured within the proximal portion of the groove such the proximal portion of the movable component remains disposed within the proximal portion of the groove when the movable component moves toward the expanded configuration.

6. The gastric tube as recited in claim 1 , wherein the outer surface of the elongate tube has an arcuate portion extending along the length of the elongate tube and a planar portion extending along the length of the elongate tube, the groove defined in the planar portion.

7. The gastric tube as recited in claim 1 , wherein the elongate tube has a cross section configuration selected from the group consisting of:
a U-shaped configuration; and
a V-shaped configuration.

8. The gastric tube as recited in claim 1 , wherein the elongate tube includes a blunt distal tip defining an opening therethrough configured for at least one of aspiration or irrigation.

9. The gastric tube as recited in claim 1 , wherein the elongate tube defines a vacuum lumen along the length thereof.

10. The gastric tube as recited in claim 9 , wherein the proximal end portion of the elongate tube defines an opening therethrough in communication with the vacuum lumen and configured to be coupled with a vacuum source.

11. The gastric tube as recited in claim 1 , wherein the movable component has a plurality of lights disposed along a length thereof.

12. A method of performing bariatric surgery, comprising:
inserting a gastric tube into an oral cavity of a patient, the gastric tubing including an elongate tube and a movable component supported in a groove defined in an outer surface of the elongate tube, the groove extending along a length of the elongate tube;
guiding the gastric tube along an enteral pathway;
repositioning the gastric tube to a selected position within a stomach of the patient; and
moving the movable component relative to the elongate tube from an unexpanded configuration in which a proximal portion of the movable component is disposed within a proximal portion of the groove and a distal portion of the movable component is disposed within a distal portion of the groove that has a different dimension than the proximal portion of the groove, toward an expanded configuration in which the distal portion of the movable component extends outwardly from an outer surface of the elongate tube into engagement with a portion of the stomach.

13. The method as recited in claim 12 , wherein the distal portion of the movable component moves outside of the distal portion of the groove when the movable component moves toward the expanded configuration.

14. The method as recited in claim 12 , wherein the proximal portion of the groove retains the proximal portion of the movable component therein and the distal portion of the groove releases the distal portion of the movable component when the movable component moves toward the expanded configuration.

15. The method as recited in claim 12 , wherein guiding the gastric tube along the enteral pathway includes advancing the gastric tube from an oral cavity through an esophagus into an antrum of the stomach.

16. The method as recited in claim 12 , wherein moving the movable component includes sliding the movable component distally relative to the elongate tube and through the groove.

17. The method as recited in claim 12 , further comprising adjusting a configuration of the movable component in response to an observed configuration of the movable component using a plurality of lights disposed along a length of the movable component.

18. A gastric tube for use in a bariatric surgical procedure, comprising:
an elongate tube including an outer surface having:
an arcuate portion extending along a length of the elongate tube; and
a planar portion extending along the length of the elongate tube, the planar portion of the outer surface defining a groove therein that extends along the length of the elongate tube, the groove including:
a proximal portion having a first dimension; and
a distal portion having a second dimension, different than the first dimension of the proximal portion; and

a movable component supported in the groove of the elongate tube and movable between an unexpanded configuration in which the movable component is disposed within the groove and an expanded configuration in which at least a portion of the movable component extends outwardly from the outer surface of the elongate tube.

19. The gastric tube as recited in claim 18 , wherein the movable component has a distal portion releasably disposed within the distal portion of the groove such that the distal portion of the movable component is disposed outside of the distal portion of the groove when the movable component moves toward the expanded configuration.

20. The gastric tube as recited in claim 18 , wherein the proximal portion of the groove is omega-shaped and the distal portion of the groove has a concave configuration.
