Problems solved by technology

In addition, surgery is not generally performed until other methods of weight loss have been attempted and have been found to be ineffective.
Persons who are severely obese are generally unable to physically perform routine daily activities, whether work-related or family functions and have a severely impaired quality of life due to the severity of their obesity.
Each type of surgery has its own risks and side effects.
Each of the foregoing therapies for severe obesity has its risks and side effects.
Each is invasive surgery and hence exhibits the risks commonly associated with all surgical procedures.
Complications may include leaking of stomach juices into the abdomen, injury to the spleen, band slippage, erosion of the band, breakdown of the staple line, and stomach pouch stretching from overeating.

Embodiment Construction

[0030]FIG. 1 is a front cross-sectional view of the esophageal-gastro-intestinal tract 40 from a lower portion of the esophagus 41 to the duodenum 42. The stomach 43 is characterized by the greater curvature 44 on the anatomical left side and the lesser curvature 45 on the anatomical right side. The tissue of the outer surfaces of those curvatures is referred to in the art as serosa tissue. As will be seen subsequently, the nature of the serosa tissue is used to advantage for its ability to bond to like serosa tissue. The fundus 46 of the greater curvature 44 forms the superior portion of the stomach 43, and traps gas and air bubbles for burping. The esophageal tract 41 enters the stomach 43 at an esophageal orifice 58 below the superior portion of the fundus 46, forming a cardiac notch 47 and an acute angle with respect to the fundus 46 known as the Angle of His 57. The lower esophageal sphincter (LES) 48 is a discriminating sphincter able to distinguish between burping gas, liquid...

Abstract

A gastric reduction system and method provides for transesophageal formation of a gastric reduction pouch of the stomach. The system includes an expandable structure which may be placed in a stomach and expanded to occupy a fractional volume of the stomach. An evacuator is then fed through the expandable structure and utilized to deflate the stomach and draw the stomach to and around the expandable structure to form the gastric reduction pouch. A self-deploying fastener is then deployed to maintain the gastric reduction pouch.

Description

FIELD OF THE INVENTION [0001] The present invention is generally directed to a therapy for treating obesity. The present invention is more particularly directed to a transesophageal gastric reduction device, system, and method for performing gastric reduction surgery while minimizing surgical invasion. BACKGROUND OF THE INVENTION [0002] Obesity is a complex chronic disease involving environment, genetic, physiologic, metabolic, behavioral and psychological components. It is the second leading cause of preventable death in the United States. [0003] Obesity affects nearly one-third of the adult American population (approximately 60 million). The number of overweight and obese Americans has continued to increase since 1960. The trend is not slowing down. Today, 64.5% of adult Americans are categorized as being overweight or obese. Each year, obesity causes at least 300,000 excess deaths in the United States, and healthcare costs of American adults with obesity amounted to approximately...
