Problems solved by technology

To add insult to injury, multiple fasteners may also be required
It is therefore often difficult to direct a single fastener, let alone several such fasteners, to its intended location with current fasteners and deployment facilities

Embodiment Construction

[0068] FIG. 1 is a front cross-sectional view of the esophagogastrointestinal tract 40 from the lower portion of the esophagus 41 to the duodenum 42 . The stomach 43 is delineated by the greater curvature 44 on the anatomically left side and the lesser curvature 45 on the anatomically right side. The tissue on the outer surface of the greater and lesser curvature of the stomach is known in the art as serosal tissue. As can be seen below, the properties of the serosal tissue can be exploited by virtue of its ability to bind similar serosal tissues. The base 46 of the greater curvature 44 forms the upper portion of the stomach 43 and traps air and air bubbles to form burps. The esophagus 41 enters the stomach 43 at the esophageal orifice below the upper portion of the fundus 46 , forming a notch of the cardia and an acute angle 57 with respect to the fundus 46 called the angle of His. The lower esophageal sphincter (LES) 48 is a differential sphincter capable of distinguishing...

Abstract

The present invention provides a tissue fasteners carried on a tissue piercing deployment wire fasten tissue layers of a mammalian body together. The fasteners include a first member, a second member, and a connecting member extending between the first and second members. The first and second members are substantially parallel to each other. The fasteners may be deployed in limited spaces and in various applications including the restoration of a gastroesophageal flap valve.

Description

technical field [0001] The present invention relates generally to a tissue fastener, and more particularly to a device for treating gastroesophageal reflux disease using the tissue fastener. The present invention more particularly relates to such a device that can be applied in a surgical environment and deployed automatically. Background technique [0002] Gastroesophageal reflux disease (GERD) is a chronic condition caused by a failure of the barrier at the gastroesophageal junction that keeps stomach contents from splashing into the esophagus. This splash is called gastroesophageal reflux. Stomach acid is used to digest meat, and when persistently splashed down the esophagus it digests the esophagus. [0003] The primary cause of reflux associated with GERD is mechanical failure of the degenerated gastroesophageal flap that closes and seals high pressure in the stomach. A grade I normal gastroesophageal flap can degenerate into a dysfunctional grade III or valve-absent...
