## 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 gastrectomy device, comprising:
a handle assembly;
a main shaft extending distally from the handle assembly; and
a deflection shaft extending along the main shaft and including:
a proximal end portion coupled to the handle assembly;
a distal end portion configured to move relative to the main shaft between a first state, in which the distal end portion is adjacent the main shaft, and a second state, in which the distal end portion protrudes outwardly relative to the main shaft and conforms to a portion of a patient's stomach, the distal end portion of the deflection shaft having a proximal end coupled to the main shaft and retained alongside the main shaft as the distal end portion moves between the first and second states, and a distal end axially fixed to a distal end portion of the main shaft, the distal end being distal of the proximal end when the distal end portion of the deflection shaft is in the second state; and
a plurality of lights disposed along a longitudinal length of the distal end portion of the deflection shaft.

### Claim 10

A gastrectomy device, comprising: a main shaft defining a longitudinally-extending lumen configured to be in communication with a vacuum source; and a deflection shaft coupled to the main shaft and including: a distal end portion configured to move relative to a distal end portion of the main shaft between an unexpanded state, in which the distal end portion of the deflection shaft is disposed alongside the distal end portion of the main shaft, and an expanded state, in which the distal end portion of the deflection shaft bows outwardly relative to the distal end portion of the main shaft to conform to a greater curvature portion of a patient's stomach, the distal end portion of the deflection shaft having a proximal end coupled to the main shaft and retained alongside the main shaft as the distal end portion of the deflection shaft moves between the unexpanded and expanded states, and a distal end axially fixed to the distal end portion of the main shaft, the distal end being distal of the proximal end when the distal end portion of the deflection shaft ism the expanded state; and a plurality, of lights disposed along a longitudinal length of the distal end portion of the deflection shaft.
