First Claim
Patent Images
1. An endoscopic gastric restriction device, comprising:
- an elongate end effector having first and second troughs extending longitudinally therethrough and adapted to receive tissue therein; and
a plurality of fasteners disposed within the end effector and configured to self-deploy to engage tissue disposed within the trough when the fasteners are released from the end effector.

Abstract
Endoscopic devices methods and devices are provided for attaching opposed walls of tissue. The methods and devices can be used to deliver a plurality of fasteners to opposed tissues, and suture extending through the fasteners can be used to pull the tissues together. The suture can be pre-woven through the fasteners, thus allowing for a quick and simply deployment. While the various methods and devices disclosed herein can be used in a variety of procedures, in certain exemplary embodiments the methods and devices are used to pull together opposed walls of the stomach to form a stomach pouch within the stomach which reduces the rate of gastric emptying.

25. A method for creating a gastric restriction, comprising:
-
introducing an elongate member through an esophagus to position an end effector on the elongate member within a stomach, the end effector flexing as it passes through the esophagus; suctioning tissue into a trough formed in the end effector; delivering a plurality of fasteners to the tissue disposed within the trough; removing the elongate member; and cinching a suture coupled to the plurality of fasteners. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33)
