Gastrointestinal implant system

Abstract

The present invention provides devices and methods for attachment of an endolumenal gastrointestinal device, such as an artificial stoma device, a gastrointestinal bypass sleeve or other therapeutic or diagnostic device, within a patient's digestive tract. In one application of the invention, an endolumenal bypass sleeve is removeably attached in the vicinity of the gastroesophageal junction to treat obesity and / or its comorbidities, such as diabetes. The bypass sleeve may be at least partially deployed by eversion.

AI Technical Summary

Benefits of technology

"The present invention provides an attachment system for attaching a device to the mucosal side of a wall of the gastrointestinal tract. The system includes a gastrointestinal attachment cuff and a tension element, such as a suture, for transmural attachment of the cuff to the mucosal layer. The system also includes at least one engagement surface for removable or permanent coupling to a gastric bypass tube. The attachment is made by advancing the tension element through the wall and placing a retention surface in contact with the serosal surface. The system can be used endoscopically and the changes to the serosal tissue can be caused by the tension element or an active agent. The technical effect of the invention is to provide a secure and reliable attachment system for attaching devices to the gastrointestinal tract."

Problems solved by technology

The medical sleeve described in these patents are said to reduce the surface area available for absorption in the stomach, however it is not configured to effectively reduce the volume of the stomach nor will the device described isolate ingested food from stomach secretions.

The sleeve devices described in these patents are said to be placed at the lower end of the stomach and therefore do not serve to isolate ingested food from the digestive secretions of the stomach.
