## Abstract

A gastrectomy device includes an elongated member defining a centerline that extends through proximal and distal ends thereof. A shape modification member coupled to the elongated member is movable relative to the centerline of the elongated member. The shape modification member is movable between a first state, adjacent to the elongated member, and a second state, spaced from the elongated member. The shape modification member conforms to a portion of a patient's stomach in the second state.

## Claims

### Claim 1

A method of performing a sleeve gastrectomy in the stomach, comprising:
inserting a tubular guide through the esophagus and into the stomach;
extending an engaging member outwardly from the tubular guide against the greater curvature of the stomach;
illuminating at least a portion of the engaging member;
retracting the engaging member; and
resecting the stomach using a surgical stapler, forming a sleeve shaped portion of the stomach, and removing a remainder of the stomach.

### Claim 2

A method of performing a sleeve gastrectomy in the stomach, comprising:
inserting a tubular guide through an esophagus and into the stomach;
extending an engaging member outwardly from the tubular guide against a greater curvature of the stomach;
partially resecting the stomach using a surgical stapler;
retracting the engaging member; and
completing the resection of the stomach, forming a sleeve shaped portion of the stomach, and removing a remainder of the stomach.

### Claim 3 (depends on 2)

The method according to claim 2, further comprising activating an array of lights.
