Abstract

Endoscopic plicators are passed transorally into the stomach and used to plicate stomach tissue by engaging tissue from inside of the stomach and drawing it inwardly. The tissue is drawn inwardly into a vacuum chamber, causing sections of serosal tissue on the exterior of the stomach to be positioned facing one another. The plicators allow the opposed sections of tissue to be moved into contact with one another, and preferably deliver sutures, staples or other means for maintaining contact between the tissue sections at least until serosal bonds form between them. Each of these steps may be performed wholly from the inside of the stomach and thus can eliminate the need for any surgical or laparscopic intervention. After one or more plications is formed, medical devices may be coupled to the plication(s) for retention within the stomach.

Claims17

Dependent claims

An endoscopic stapler for fastening tissue, comprising:

a fastening head including:
(i) a first portion including a staple cartridge with one or more staples therein;
(ii) a second portion including an anvil;
(iii) at least one hinge member connecting the first portion and the second portion for movement toward and away from one another along an axis extending through the first portion and the second portion, wherein each hinge member of said at least one hinge member includes first and second sections that are mounted on said first and second portions, respectively;
and
(iv) a flexible membrane extending between the first portion and the second portion to define a tissue capture region therebetween, wherein the at least one hinge member is configured such that movement of the first portion and the second portion toward one another to staple tissue positioned in the tissue capture region corresponds to movement of the first and second sections of each hinge member outwardly away from said axis to enlarge the tissue capture region in a direction orthogonal to said axis.
