Embodiment Construction

[0072] The present invention relates to an endoscopic tissue folding and fastening device for forming tissue folds in the gastric cavity to reduce the volume of the cavity. By forming and securing multiple folds along the inner wall of the stomach cavity, the present invention reduces the surface area within the cavity, thereby reducing the volume of food available in the stomach. The present invention provides a simplified tissue folding process in which the tissue folds are held by staples, absorbable or removable clips, thereby allowing the process to be easily reversed. In addition, the present invention allows for oral entry of the device into the body and folding of a larger area of ​​the gastric cavity, thereby providing effective bariatric treatment without the trauma that occurs during open surgical folding.

[0073] FIG. 1 shows a first embodiment of a tissue folding device 20 according to the invention. Tissue folding device 20 includes a folding member or end effe...

Abstract

A device for creating a plication within a hollow organ. The device has an elongated member with distal and proximal ends. The distal end is for insertion into a body cavity. The elongated member has an end effector at its distal end. The end effector includes an outer cylinder having at least one opening in its cylindrical wall. The end effector also has an inner cylinder having at least one opening in its cylindrical wall. The inner cylinder is at least partially disposed within the outer cylinder such that the apertures can at least partially overlap. In addition, the cylinders are rotatable with respect to each other. In addition, the device includes a tubular channel running through the elongated member which is in fluid communication with the end effector. The channel has a vacuum source attached at its proximal end.

Description

technical field [0001] The present invention relates generally to a bariatric device and, more particularly, to a device for oral entry into the body for folding and fastening regions of gastric tissue to achieve gastric volume reduction. Background technique [0002] The proportion of the world's population suffering from morbid obesity is steadily increasing. Severely obese people are more prone to heart disease, stroke, diabetes, lung disease and are more vulnerable to accidental injuries. Because of the impact morbid obesity has on the lives of patients, research is being conducted on methods of treating morbid obesity. [0003] Numerous non-surgical treatments for morbid obesity have been attempted, but ultimately largely unsuccessful. Dietary advice, behavior modification, closure of the palate with a wire, and pharmacological approaches have been tried, but all have failed to change the situation. Mechanical devices for insertion into the body by non-surgical means...
