The one or more medical devices may include a laparoscopic sleeve gastrectomy stapling guide in conjunction with a calibration tube in accordance with one or more examples. According to an example, the calibration tube may be a flared, multi-diameter calibration tube. The flared, multi-diameter calibration tube may have a first diameter along a portion of the tube and a second diameter that may larger than the first diameter along at least another portion of the tube. The calibration tube may be used in conjunction with the stapling guide to align stomach such that it may be stapled along the stapling guide (e.g., to perform the vertical sleeve gastrectomy). ## Claims ### Claim at position 1 1-20. (canceled) ### Claim 21 A calibration tube for a sleeve gastrectomy, comprising: (a) a tube having a proximal end and a distal end with a length extending therebetween, wherein the tube is configured to be inserted into an interior of a stomach, the stomach having a lesser curvature and a greater curvature; (b) at least one light source comprising a plurality of light elements disposed along the length of the tube, wherein one or more of the plurality of light elements is disposed on a portion of the tube for indicating accurate placement of the tube relative to the stomach at a predetermined anatomical landmark; and (c) at least one channel formed in the tube. ### Claim 22 (depends on 21) The calibration tube of claim 21, wherein the predetermined anatomical landmark is an incisura angularis, and wherein after being inserted into the interior of the stomach, the portion of the tube having the one or more plurality of light elements is positioned at about the incisura angularis along the lesser curvature of the stomach. ### Claim 23 (depends on 21) The calibration tube of claim 21, wherein the plurality of light elements comprise at least one optic fiber, at least one LED, or combinations thereof. ### Claim 24 (depends on 21) The calibration tube of claim 21, wherein the portion is a flared portion at about the distal end of the tube. ### Claim 25 (depends on 24) The calibration tube of claim 24, wherein the tube has a first diameter and the flared portion has a second diameter larger than the first diameter. ### Claim 26 (depends on 24) The surgical system of claim 24, wherein the flared portion comprises a singular balloon that is inflated and deflated from at about the proximal end of the tube. ### Claim 27 (depends on 24) The calibration tube of claim 24, wherein the flared portion comprises a first flared portion and a second flared portion, wherein the first flared portion is pivotally coupled to the second flared portion. ### Claim 28 (depends on 27) The calibration tube of claim 27, wherein the first flared portion is pivotally coupled to the second flared portion through a hinge. ### Claim 29 (depends on 24) The calibration tube of claim 24, wherein the flared portion comprises a gripping surface having a plurality of teeth that secure the flared portion at about the distal end of the tube. ### Claim 30 (depends on 29) The calibration tube of claim 29, wherein a cap is coupled to a proximal end of the flared portion and a fastener is coupled to a distal end of the flared portion, wherein the cap and fastener are configured to further secure the flared portion at about the distal end of the tube. ### Claim 31 (depends on 21) The calibration tube of claim 21, wherein the calibration tube is configured for use with a sleeve gastrectomy stapler having a first end and a second end configured to be positioned on an exterior of the stomach relative to and anatomically lateral to the tube to define a resection line, wherein operating the stapler provides a complete gastrectomy staple line along the resection line to resect a portion of the stomach to form a sleeve. ### Claim 32 A gastric calibration tube for performing sleeve gastrectomies, comprising: (a) a tube having a predetermined length, wherein the tube is configured to be inserted into an interior of a stomach, the stomach having a lesser curvature and a greater curvature; (b) a first light source having a plurality of light elements disposed along the length of the tube; (c) a second light source having at least one light element positioned at a portion of the tube for indicating accurate placement of the tube relative to the stomach at a predetermined anatomical landmark, wherein after being inserted, the portion of the tube having the second light source is positioned along the lesser curvature of the stomach; and (d) at least one channel formed in the tube for suction or inflation. ### Claim 33 (depends on 32) The gastric calibration tube of claim 32, wherein the predetermined anatomical landmark is an incisura angularis. ### Claim 34 (depends on 32) The gastric calibration tube of claim 32, wherein the tube further comprises a proximal end and a distal end with the predetermined length extending therebetween. ### Claim 35 (depends on 32) The gastric calibration tube of claim 32, wherein the first light source and the second light source each comprise at least one optic fiber, at least one LED, or combinations thereof. ### Claim 36 (depends on 34) The calibration tube of claim 34, wherein the portion is a flared portion at about the distal end of the tube, the tube having a first diameter and the flared portion having a second diameter larger than the first diameter. ### Claim 37 (depends on 36) The surgical system of claim 36, wherein the flared portion comprises a singular balloon that is inflated and deflated from at about the proximal end of the tube. ### Claim 38 (depends on 36) The calibration tube of claim 36, wherein the flared portion comprises a first flared portion and a second flared portion, wherein the first flared portion is pivotally coupled to the second flared portion through a hinge. ### Claim 39 (depends on 36) The calibration tube of claim 36, wherein the flared portion comprises a gripping surface having a plurality of teeth that secure the flared portion at about the distal end of the tube. ### Claim 40 (depends on 39) The calibration tube of claim 39, wherein a cap is coupled to a proximal end of the flared portion and a fastener is coupled to a distal end of the flared portion, wherein the cap and fastener are configured to further secure the flared portion at about the distal end of the tube.
