Abstract
A method for forming a valve-like mechanism in a body of a mammal having an esophagus extending through a lower esophageal sphincter to a stomach and formed by a wall having a muscle layer and a mucosal layer. The method comprises the step of forming at least one implant in the muscle layer of the wall in the vicinity of the lower esophageal sphincter. The at least one implant inhibits opening of esophagus at the lower esophageal sphincter and causes the mucosal layer to appose in the vicinity of the implants.
Claims21
A method for forming a valve-like mechanism in a body of a mammal having an esophagus extending through a lower esophageal sphincter to a stomach and formed by a wall having a muscle layer and a mucosal layer comprising the step of forming at least one implant in the muscle layer of the wall in the vicinity of the lower esophageal sphincter whereby the at least one implant inhibits opening of esophagus at the lower esophageal sphincter and causes the mucosal layer to appose in the vicinity of the implants.
A method for increasing the competency of a sphincter in a gastrointestinal tract having a first chamber extending through the sphincter to a second chamber having a pressure therein, said first chamber being defined by a wall having a muscle layer and a mucosal layer comprising the step of creating a valve-like structure in the muscle layer in the vicinity of the sphincter whereby with increased pressure the valve-like structure causes the mucosal layer to appose in the vicinity of the valve thereby lessening reflux from the second chamber to the first chamber.
A method for increasing the competency of a sphincter in a gastrointestinal tract having a chamber extending to the sphincter, the chamber having a pressure therein and defined by a wall having a muscle layer and a mucosal layer comprising the step of creating a valve-like structure in the muscle layer in the vicinity of the sphincter whereby with increased pressure in the chamber the valve-like structure causes the mucosal layer to appose in the vicinity of the valve thereby lessening incontinence of the chamber.
A method for creating an arcuate implant in a wall having circular and longitudinal muscle layers and forming a natural body passageway comprising the steps of introducing a material between the circular and longitudinal muscle layers so that the material extends around at least a portion of the wall to form an arcuate implant.
