Abstract
Abstract Methods and devices are disclosed for performing laparoscopic gastroplasty for the treatment of morbid obesity. The method utilizes a stapling device or clip and a nasogastric tube for positioning the stapling device. A non-absorbable staple support strip or clip is to form and support a passage between a proximal pouch and a distal region in the stomach.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
236 words
A method for performing laparoscopic gastroplasty on a patient, said method comprising: percutaneously introducing a plurality of trocars through the patient's abdominal wall; visualizing the patient's stomach using a laparoscope disposed in one of the trocars; manipulating the stomach to expose the lesser curvature, anterior, and posterior walls of the stomach to the laparoscope; dissecting the stomach from the mesentery along the lesser and greater curvatures dividing the stomach along a line into a proximal pouch adjacent the esophagus and a distal region; introducing a banding device for encircling the stomach along a dissecting line for defining the proximal pouch, the distal region with an aperture defined between the proximal pouch and the distal region; introducing a nasogastric tube into the stomach so that it passes through the aperture; inflating a first balloon on the nasogastric tube distally of the aperture and a second balloon in the esophagus, to seal the proximal pouch in the stomach; introducing a measured volume of fluid into the proximal pouch through the nasogastric tube until the pouch is filled; repositioning the banding device and reintroducing fluid until the position of the banding device provides a preselected fluid volume upon filling; and closing the banding device over the stomach along a line defined by the aperture in the band at its final position, with a passage between the proximal pouch and distal region of the stomach being defined by the aperture.
Claim 2
Independent Claim
236 words

Claim 3
Dependent Claim
69 words
A method for performing laparoscopic gastroplasty on a patient according to claim 1 and wherein said introducing of said banding device includes: introducing a band having staples thereon with a portion of said band defining said aperture; and, said closing step includes: closing said staples on said band to define said aperture with said band and fastening the distal ends of said band with said staples across said stomach.
Claim 4
Dependent Claim
58 words
A method for performing laparoscopic gastroplasty on a patient according to claim 1 and wherein said introduction of said banding device includes: introducing a clip having opposed portions thereon with said opposed portions each defining portions of said aperture; and said closing step includes: closing said clip about said stomach to define a proximal pouch to said stomach.
Claim 5
Dependent Claim
44 words
A method for performing laparoscopic gastroplasty on a patient according to claim 3 and including the steps of: fastening mesh to said banding device, and, stapling said mesh to at least one wall of said stomach to insure against migration of said banding device.
Claim 6
Dependent Claim
33 words
A method for performing laparoscopic gastroplasty on a patient according to claim 1 and including the further step of: examining the arterial blood flow of said stomach during closing of said banding device.
Claim 7
Dependent Claim
82 words
A method for performing laparoscopic gastroplasty on a patient according to claim 1 and wherein said introducing step includes: laparoscopically passing a member from the anterior of said patient around the posterior of said stomach and threading said member exterior of said patient; attaching a banding device to said exteriorly threaded member; drawing said banding device interiorly of said patient utilizing said member to lodge a portion of said device posterior of said stomach; and, fastening said banding device over said stomach.
