an actuator, the actuator being coupled with the handle and operatively coupled with the biasing member such that the actuator selectively tensions the biasing member to provide the first clamping force in the first stage and the second clamping force in the second stagea first position in which the distal end of the shaft is fixedly coupled with at least one of the first clamp member or the second clamp member such that the clamp is operably configured for insertion into the stomach in accordance with the medical procedure;
a second position in which the distal end of the shaft is fixedly coupled with at least one of the first clamp member or the second clamp member such that the clamp is operably configured to clamp the stomach in accordance with the medical procedure;
a third position in which the distal end of the shaft is fixedly coupled with at least one of the first clamp member or the second clamp such that the clamp is operably configured for extraction from the stomach after performance of the medical procedure, andwherein the first stage comprises the first clamping force being from about 0.5 g/mm2 to about 4 g/mm2.

Abstract
The present invention relates to apparatuses and methods of using a resection line guide in various medical procedures. A resection line guide may include a first clamp member and a second clamp member configured to be positioned on a first side and a second side generally opposite that of the first side of an anatomical structure, such as, for example, a stomach. The clamp members may be configured to provide a clamping force on the stomach to secure the guide to the stomach. Further, at least one flexible member may be operatively coupled to the clamp members. The flexible member may be configured to be tensioned so as to provide at least a portion of the clamping force on the stomach.
