Abstract:
A system for stapling tissue comprising:an operative head including a pair of opposed, curved tissue clamping jaws sized to pass through an esophagus, the jaws being moveable with respect to one another between an open tissue receiving configuration and a closed tissue clamping configuration, a first one of the curved jaws including a stapling mechanism and a second one of the jaws including a staple forming anvil surface, the stapling mechanism including stapling slots through which staples are fired arranged in a row extending from a proximal end of the first jaw to a distal end thereof, wherein the operative head further includes a first jaw moving mechanism for gross adjustment of the position of the jaws relative to one another and a second jaw moving mechanism for fine adjustment of the jaws relative to one another and wherein the second jaw moving mechanism includes a substantially C-shaped clamp received around the first and second jaws; and a control handle which, when the operative head is in an operative position within one of a patient's stomach and esophagus, remains outside the patient, the control handle including a first actuator for moving the jaws relative to one another and a second actuator for operating the stapling mechanism.
