1. A surgical method, comprising:
- translumenally advancing a flexible elongate shaft having a vacuum chamber at a distal end thereof into a stomach of a patient;
applying a vacuum force through the vacuum chamber to adhere stomach tissue to the vacuum chamber; and
with the tissue adhered to the vacuum chamber, moving the vacuum chamber relative to the shaft in a direction transverse to a longitudinal axis of the shaft to form a fold in the stomach tissue.

Abstract
A system for tissue approximation and fixation is described herein. A device is advanced in a minimally invasive manner within a patient'"'"'s body to create one or several divisions or plications within a hollow body organ. The system comprises a stapler assembly having a tissue acquisition member and a tissue fixation member. The stapler assembly approximates tissue from within the hollow body organ with the acquisition member and then affixes the approximated tissue with the fixation member. In one method, the system can be used as a secondary procedure to reduce the size of a stoma within the hollow body organ.

6. A surgical method, comprising:
-
translumenally advancing a flexible elongate shaft having a pod extending from a distal end thereof into a stomach of a patient such that the pod leads the shaft into the stomach; applying a vacuum force via the pod to adhere stomach tissue to the pod;
with the tissue adhered to the pod, moving the pod radially relative to the shaft to form a fold in the stomach tissue; andapplying a fastener to the tissue fold to affix the tissue fold. - View Dependent Claims (7)

8. A surgical device, comprising:
-
a flexible elongate shaft configured to be translumenally advanced into a body of a patient; a pod assembly at a distal end of the shaft, the pod assembly being configured to apply a vacuum force to tissue of the patient, and the pod assembly being configured to move relative to the shaft between a first configuration and a second configuration, the pod assembly in the second configuration being moved relative to the shaft in a direction transverse to a longitudinal axis of the shaft such that the pod assembly is a greater radial distance away from the longitudinal axis of the shaft than when the pod assembly is in the first configuration; and an actuator extending along the shaft and being configured to be actuated to selectively move the pod assembly between the first configuration and the second configuration; wherein the pod assembly includes opposed first and second pod members; wherein when the pod assembly is in the first configuration, the first pod member is at a first radial position relative to the longitudinal axis of the shaft and the second pod member is at a second radial position relative to the longitudinal axis of the shaft; and wherein when the pod assembly is in the second configuration, the first pod member is at a third radial position relative to the longitudinal axis of the shaft and the second pod member remains at the second radial position relative to the longitudinal axis of the shaft, the third radial position being farther away from the longitudinal axis than the first radial position. - View Dependent Claims (9, 10, 11, 12, 13)

14. A surgical method using a device comprising a flexible elongate shaft configured to be translumenally advanced into a body of a patient, and a pot assembly at a distal end of the shaft, the pod assembly being configured to apply a vacuum force to tissue of the patient, and the pod assembly being configured to move relative to the shaft between a first configuration and a second configuration, the pod assembly in the second configuration being moved relative to the shaft in a direction transverse to a longitudinal axis of the shaft such that the pod assembly is a greater radial distance away from the longitudinal axis of the shaft than when the pod assembly is in the first configuration, the method comprising:
-
advancing the distal end of the shaft into the body of the patient, wherein advancing the distal end of the shaft includes advancing the distal end of the shaft into a stomach of the patient; positioning the pod assembly adjacent to the tissue of the patient; applying the vacuum force; and moving the pod assembly from the first configuration to the second configuration, thereby forming a fold in the tissue; wherein the pod assembly includes opposed first and second pod members; wherein when the pod assembly is in the first configuration, the first pod member is at a first radical position relative to the longitudinal axis of the shaft and the second pod member is at a second radical position relative to the longitudinal axis of the shaft; and wherein when the pod assembly is in the second configuration the first pod member is at a third radial position relative to the longitudinal axis of the shaft and the second pod member remains at the second radical position relative to the longitudinal axis of the shaft, the third radial position being farther away from the longitudinal axis than the first radial position. - View Dependent Claims (15)

16. A surgical method using a device comprising a flexible elongate shaft configured to be translumenally advanced into a body of a patient, and a pod assembly at a distal end of the shaft, the pod assembly being configured to apply a vacuum force to a tissue of the patient, and the pod assembly being configured to move relative to the shaft between a first configuration and a second configuration, the pod assembly in the second configuration being moved relative to the shaft in a direction transverse to a longitudinal axis of the shaft such that the pod assembly is a greater radial distance away from the longitudinal axis of the shaft than when the pod assembly is a greater radical distance away from the longitudinal axis of the shaft than when the pod assembly is in the first configuration, the method comprising:
-
advancing the distal end of the shaft into the body of the patient, wherein advancing the distal end of the shaft includes translumenally advancing the distal end of the shaft into the body of the patient; positioning the pod assembly adjacent to the tissue of the patient; applying the vacuum force; and moving the pod assembly from the first configuration to the second configuration, thereby forming a fold in the tissue; wherein the pod assembly includes opposed first and second pod members; wherein when the pod assembly is in the first configuration, the first pod member is at a first radical position relative to the longitudinal axis of the shaft and the second pod member is at a second radial position relative to the longitudinal axis of the shaft; and wherein when the pod assembly is in the second configuration, the first pod member is at a third radial position relative to the longitudinal axis of the shaft and the second pod member remains at the second radial position relative to the longitudinal axis of the shaft, the third radial position being farther away from the longitudinal axis than the first radial position. - View Dependent Claims (17, 18)
