1. An apparatus for performing a sleeve gastrectomy, the apparatus comprising:
(a) a bougie for insertion into an interior of a stomach, the bougie having a proximal bougie end and a distal bougie end;
(b) an inflation lumen having a proximal lumen end and a distal lumen end, the inflation lumen extending from the proximal bougie end through the distal bougie end;
(c) a fluid delivery system coupled with the inflation lumen, the fluid delivery system having a first mode in which the fluid delivery system delivers a positive pressure in a predetermined positive pressure range into the stomach prior to the stomach being resected, the predetermined positive pressure range being based on a size or a shape of the stomach prior to the stomach being resected; and
(d) a monitor coupled with the inflation lumen;
wherein the bougie is configured to define a resection line for the sleeve gastrectomy when the predetermined positive pressure range is achieved within the stomach, wherein the resection line is defined at least partially by the position of the bougie relative to a second medical device;
wherein the bougie includes at least one sensor coupled with the distal bougie end for monitoring a pressure within the stomach, wherein the monitor is configured to provide an indication that the predetermined positive pressure range is reached to the second medical device based on output of the at least one sensor, and wherein the indication is configured to cause the second medical device to clamp the stomach; and
wherein the apparatus is configured to simultaneously deliver the positive pressure and provide suction.
