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 having a non-circular cross section along at least a portion of a length thereof, the elongate tube including:
an outer surface;
a proximal end portion defining an opening therein configured to be coupled with a vacuum source;
a distal end portion having a blunt tip; and
a lumen defined along the length of the elongate tube, the lumen being in communication with the opening of the proximal end portion; and
a movable component supported on the outer surface, the movable component being movable between an unexpanded configuration in which the movable component is disposed in abutting engagement with the outer surface and an expanded configuration in which the movable component bows outwardly from the outer surface of the elongate tube.

2 . The gastric tube as recited in claim 1 , wherein the non-circular cross section is selected from the group consisting of a U-shaped configuration and a V-shaped configuration.

3 . The gastric tube as recited in claim 1 , wherein the outer surface defines a groove therein extending along at least a portion of the length of the elongate tube.

4 . The gastric tube as recited in claim 3 , wherein a proximal portion of the movable component is slidably disposed within the groove.

5 . The gastric tube as recited in claim 4 , wherein the movable component has a distal end that is fixedly coupled to the distal end portion of the elongate tube.

6 . The gastric tube as recited in claim 3 , wherein the movable component is a sail member.

7 . The gastric tube as recited in claim 6 , wherein the sail member has a plurality of lights disposed thereon.

8 . The gastric tube as recited in claim 6 , wherein an entirety of the sail member is disposed within the groove when the sail member is in the unexpanded configuration.

9 . The gastric tube as recited in claim 3 , wherein the outer surface 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 being defined in the planar portion.

10 . The gastric tube as recited in claim 9 , wherein the movable component includes a proximal portion, the groove configured to retain the proximal portion of the movable component therein.

11 . The gastric tube as recited in claim 1 , wherein the blunt tip defines an opening formed therein configured and dimensioned for at least one of aspiration or irrigation.

12 . A method of performing bariatric surgery, comprising:
providing a gastric tube including:
an elongate tube having a non-circular cross section along at least a portion of a length thereof, the elongate tube including:
an outer surface defining a groove therein that extends along at least a portion of the length of the elongate tube;
a proximal end portion defining an opening therein configured to be coupled with a vacuum source;
a distal end portion having a blunt tip; and
a lumen defined along the length of the elongate tube, the lumen being in communication with the opening of the proximal end portion; and

a movable component supported in the groove;
inserting the gastric tube into an oral cavity of a patient; guiding the gastric tube along an enteral pathway; repositioning the gastric tube based on an observed position of the outer surface to a selected position within a stomach of the patient; moving the movable component from an unexpanded configuration to an expanded configuration in which the movable component bows outwardly from the outer surface of the elongate tube into engagement with a portion of the stomach; and transecting a portion of the stomach.

13 . The method of performing bariatric surgery 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.

14 . The method of performing bariatric surgery 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.

15 . The method of performing bariatric surgery as recited in claim 12 , wherein the non-circular cross section is selected from the group consisting of a U-shaped configuration and a V-shaped configuration.

16 . The method of performing bariatric surgery as recited in claim 12 , wherein the movable component has a distal end that is fixedly coupled to the distal end portion of the elongate tube.

17 . The method of performing bariatric surgery as recited in claim 12 , wherein the movable component is a sail member.

18 . The method of performing bariatric surgery as recited in claim 17 , wherein a proximal portion of the sail member is retained within the groove.

19 . The method of performing bariatric surgery as recited in claim 17 , wherein the sail member has a plurality of lights disposed thereon.

20 . The method of performing bariatric surgery as recited in claim 19 , further including adjusting the configuration of the sail member in response to an observed configuration of the sail member.
