Intragastic implant devices

Abstract

An intragastric implant comprises an anchor and a therapeutic device or a diagnostic device. The anchor is adapted to extend between the fundus and the pyloric valve of a stomach, to be retained without attachment to the stomach wall, and to anchor the device within the stomach with a relatively stable position and orientation. The therapeutic or diagnostic device is adapted to extend from the esophagus or stomach to the intestines or stomach. The therapeutic or diagnostic device, when extending into the esophagus, will be slidably received through the gastroesophageal junction and, when extending into the intestines, will be slidably received in the pyloric valve.

What is claimed is: 
     
         1 . An intragastric implant comprising:
 an elongate anchor adapted to extend substantially from the fundus to the pyloric valve in a patient; and   a bariatric sleeve coupled to the anchor and having a central passage with an opening positionable within the esophagus and an outlet positionable in the stomach or intestines.
