1. A system for sleeve gastrectomy comprising:
(a) a first medical device comprising a shaping portion for insertion into an interior of a stomach, the shaping portion comprising at least one balloon portion, and an inflation portion, wherein the inflation portion is operably configured to provide positive pressure or negative pressure to the stomach;
(b) a second medical device comprising a stapler or clamp configured to be positioned externally on the stomach laterally adjacent to the first medical device;
(c) a control system comprising:
(i) one or more sensors configured to generate a balloon channel dataset based on detected pressure within the at least one balloon portion and a stomach channel dataset based on detected pressure within the stomach;
(ii) one or more pumps operable to selectively provide positive pressure or negative pressure to the at least one balloon portion and the inflation portion;
(iii) one or more processors in communication with the one or more sensors and configured to selectively operate the one or more pumps;
wherein the one or more processors are configured to:
(i) operate the one or more pumps to automatically inflate the at least one balloon portion to a preconfigured balloon pressure based on the balloon channel dataset;
(ii) operate the one or more pumps to automatically inflate the stomach to a preconfigured stomach pressure based on the stomach channel dataset;
(iii) while operating the one or more pumps to automatically inflate the stomach, monitor the balloon channel dataset and identify a pressure change in the balloon channel dataset that corresponds to the second medical device becoming adjacent and snug to the shaping portion; and
(iv) in response to the pressure change, provide an indication that the second medical device is adjacent and snug to the shaping portion.
