METHODS AND DEVICES FOR TISSUE RECONFIGURATION

摘要

A method includes advancing an apparatus (10) including an elongated member (12) transorally into the stomach. The apparatus (10) includes a distal end effector (15) having first and second members (16) configured to engage tissue. The first and second members (16) are movable relatively toward one another generally in a first plane. The method includes moving the distal end effector relative to the elongated member (12) in the first plane such that the distal end effector is retroflexed out of alignment with the elongated member (16) to position the first and second members (16) for engagement with the tissue. At least one of the first and second members (16) carries a fixation device (22) for fixing engaged portions of tissue together.
