The present invention pertains to an apparatus and method which enable the performance of vertical banded gastroplasty (VBG) without the use of staples. Further, a laparoscopic instrument which can be used in combination with the VBG apparatus and method is also disclosed. The laparoscopic instrument can also be used in combination with surgically functional elements other than the VBG apparatus. A particular advantage of the laparoscopic instrument is that surgically functional elements attached at the leading edge of levered jaws of the instrument can be rotated at least 180 degrees in a plane which is substantially parallel to a plane passing horizontally through the longitudinal centerline of the levered jaws. |

DETAILED DESCRIPTION In accordance with the present invention, an apparatus and method which enable vertical banded gastroplasty (VBG) to be performed without the use of staples are disclosed.
Further, a laparoscopic instrument which can be used in combination with various devices for permitting different kinds of laparoscopic surgery is also disclosed.
This laparoscopic instrument can be used in combination with the apparatus and method for enabling VBG.
The apparatus of the present invention which pertains to VBG is a pouch-forming device which remains in the body of the patient after surgery.
The pouch-forming device is comprised of at least two clamping bars designed to act in conjunction with each other and preferably having at least one banding strip attached to corresponding ends of each of the clamping bars.
This combination of clamping bars and banding strip is applied to the stomach in a manner so that an upper gastric pouch is formed using the walls of the stomach.
The clamping bars are applied with one bar anterior and one bar posterior to the exterior of the stomach so that when the bars are "clamped" together, a tubular-shaped (initially) pouch is formed.
The upper ends of the clamping bars are located at the junction of the esophagus with the stomach.
The lower ends of the clamping bars form the base of the initially tubular-shaped pouch and are attached to the banding strip which forms a confined, banded opening from the base of the pouch.
The banded opening is located away from the junction of the esophagus with the stomach, so that the clamping bars tend to be somewhat vertical relative to the upper and lower openings from the stomach, thus, the terminology "VBG" applies.
The clamping bars typically have tissue piercing pins which protrude from a first clamping bar with a pin-receiving openings and a pin locking mechanism in the corresponding, second clamping bar.
The pin length is designed to permit the stomach tissue held between the first and second clamping bars, and pierced by the pins to receive normal sustenance and to heal around the pins, so that minimal alteration of the stomach tissue occurs due to the presence of the clamping bars
