Apparatus and method for securing the stomach to the diaphragm for use, for example, in treating hiatal hernias and gastroesophageal reflux disease
View Patent ↗A patient's stomach may be secured to the patient's diaphragm. A method to accomplish this includes visualizing a wall of a patient's stomach adjacent the patient's diaphragm from within the patient's stomach, inserting a fastener deployment apparatus down the patient's esophagus and into the mammalian's stomach, and fastening the patient's stomach to the patient's diaphragm with the fastener deployment apparatus and from within the stomach. The procedure may be employed to advantage to treat a hiatal hernia, for example, either alone or in conjunction with the restoration of the patient's gastroesophageal flap valve.
1. A method for securing the stomach to the diaphragm and for restoring a gastroesophogeal flap valve, comprising:
selecting a first portion of a stomach tissue of a patient;
restoring a gastroesophageal valve using the first portion of the stomach tissue, the first portion of the stomach tissue forming an intersection between the esophagus and the stomach;
providing a tissue fastening device having a fastener, the fastener having a first member and a second member, the first member having a tissue piercing pointed tip;
advancing the tissue fastening device down the throat of the patient;
securing a second portion of stomach tissue, the second portion of tissue being a portion of the stomach separate from the first portion of tissue and being a portion of the greater curvature spaced apart from an esophageal opening, the securing step being carried out after restoring the gastroesophageal valve during the restoring step;
advancing a tissue piercing deployment wire through the first portion of tissue and through the second portion of tissue and locking the tissue piercing deployment wire in place;
using a pusher, advancing the fastener over the tissue piercing deployment wire extending through a channel in the first member and inserting the tissue piercing pointed tip of the first member through the first portion of tissue and the second portion of tissue; and
withdrawing the tissue piercing deployment wire from the channel through a lengthwise slit extending the entire length of the first member in order to deploy the first member through the second portion of tissue.
2. The method of claim 1 , further comprising the step of:
inflating the stomach before the selecting step.
