Methods and devices for endosonography-guided fundopexy
First Claim
1. A tissue securement apparatus for creating a gastric fundoplexy comprising:
- a hollow needle with proximal and distal end portions, the needle comprising a needle body and a detachable needle tip, a stylet positioned coaxially inside the needle body with a connecting element positioned inside the needle and extending from the proximal needle end portion to the distal needle end portion, said connecting element coupled to the needle tip at one end, the needle configured to be inserted through an esophageal and fundal wall and then withdrawn to leave behind the distal portion of the connecting element in the fundus.

Abstract
The present invention relates to a tissue securement system, device and method for endoscopy or endosonography-guided transluminal interventions whereby a ligation or anchor is placed and secured into soft tissue. An objective of this invention is to provide a method to reduce gastroesophageal reflux by endosonography-guided intervention. Specifically, endosonography is used to insert a ligation element through the esophageal wall, through the diaphragmatic crus and into the fundus of the stomach. This ligation element placed from the esophagus and around the angle of His that may create a barrier to gastroesophageal reflux.

11. A method for connecting a first body cavity having a first wall to a second body cavity having a second wall comprising:
-
inserting a tissue securement apparatus containing a hollow needle with proximal and distal end portions, through the first and second walls, advancing a connecting element through the needle and into the second body cavity and removing the needle, joining a proximal end of said connecting element to a ligating element, positioning grasping forceps inside the second body cavity and grasping and pulling the connecting element to position the ligating element across the first and second walls, bringing the ends of the ligating element together to form a loop that draws the first and second walls together. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A method for repairing a gastroesophageal flap valve comprising:
-
positioning a tissue securement apparatus containing a hollow needle with proximal and distal end portions along the esophageal wall, inserting the tissue securement apparatus through the esophageal wall, the diaphragmatic crura and a fundal wall of the stomach, advancing a connecting element through the needle and into the stomach and removing the needle, joining a proximal end of said connecting element to a ligating element, positioning grasping forceps inside the stomach and grasping and pulling the connecting element to position the ligating element across the esophageal wall, the diaphragmatic crura and a fundal wall of the stomach, bringing the ends of the ligating element together to form a loop that encircles the gastro-esophageal flap valve and draws the esophageal and fundal walls together. - View Dependent Claims (20, 21, 22, 23)
