Upper stomach gastric implants
First Claim
1. A system for the treatment of obesity for implantation along an esophagus at an esophageal sphincter of a patient, comprising:
- a tubular stent having, in a delivered configuration, an expanded diameter sufficient to anchor in the esophagus adjacent the esophageal sphincter and having a sidewall with a length configured to extend along the esophagus;
a resilient diaphragm member coupled to the tubular stent at a first position along the length of the tubular stent and extending across the tubular stent in a direction perpendicular to the length of the tubular stent, and having a non-closing, fixed size stoma that is always open to allow food to pass through the diaphragm member; and
an elongated obturator having a stent attachment device and a diaphragm attachment device longitudinally spaced from the stent attachment device,wherein the stent attachment device releasably attaches to the sidewall of the tubular stent at a second position along the length of the tubular stent that is spaced along the length of the tubular stent from the first position and the diaphragm attachment device releasably attaches within the stoma of the diaphragm member at the first position, andwherein attachment of the stent and the diaphragm to the respective stent attachment device and the diaphragm attachment device causes the tubular stent and the diaphragm to assume a delivery configuration in which the tubular stent is longitudinally extended and radially compressed and the diaphragm is resiliently deformed.

Abstract
A variety of passive intragastric implant devices for obesity treatment are disclosed. Such passive devices may not autonomously change shape, but instead react within the stomach to induce satiety. The devices may provide slowed entry into the stomach, thus reducing the intake capacity. Additionally, the devices may contact areas within the stomach, such as the cardia surrounding the esophageal sphincter, to stimulate satiety-inducing nerves. Some devices combine two or more of these satiety-inducing features. Methods of implant are disclosed including compressing the devices within a delivery tube and transorally advancing the devices through the esophagus to be deployed within the stomach. Removal of the devices occurs in the reverse. The implants are formed of materials that permit the implant to be compressed into a substantially linear transoral delivery configuration and that will resist degradation over a period of at least six months within the stomach.
