Abstract
A method for performing a sleeve gastrectomy includes providing a first medical device including a tube for insertion into an interior of a stomach, the tube having a proximal end and a distal end, and a shaping portion positioned at the distal end of the tube, providing an inflation lumen, and providing a second medical device, the second medical device being a stapler or clamp positioned externally on the stomach laterally adjacent to the first medical device. The method also includes introducing positive pressure into the stomach via the inflation lumen, defining a resection line for the sleeve gastrectomy, and clamping the stomach using the second medical device. The resection line is defined at least partially by the position of the second medical device relative to the first medical device when a predetermined positive pressure range is provided via the inflation lumen.
