Delivery devices and methods for gastrointestinal implants
First Claim
1. A system for delivery and implantation of a gastrointestinal device within one or more of a pyloric antrum, a pylorus, a duodenal bulb, a duodenum, and a jejunum of a patient'"'"'s gastrointestinal tract, the system comprising:
- an anchor having a collapsed configuration for delivery and an expanded configuration for anchoring within one or more of the pyloric antrum, the pylorus, and the duodenum;
an intestinal bypass sleeve coupled to and extending from an end of the anchor;
an anchor and sleeve delivery device comprising;
a distal outer capsule having a first lumen that is sized and configured to retain the anchor in the collapsed configuration and a second lumen disposed adjacent to the first lumen;
a proximal outer sheath coupled to the distal outer capsule;
a sleeve delivery catheter slidably disposed within the second lumen of the distal outer capsule and the proximal outer sheath, the sleeve delivery catheter having a longitudinal guide wire lumen sized and shaped to accept a guide wire, the sleeve delivery catheter having a sleeve coupling feature for releasably coupling to the intestinal bypass sleeve; and
an anchor pusher slidably disposed in the proximal outer sheath and configured to extend into the first lumen of the distal outer capsule to push the anchor out of the distal outer capsule and deploy the anchor to the expanded configuration.

Abstract
Several gastrointestinal surgery procedures are effective as treatments for metabolic disorders such as obesity and diabetes. Minimally invasive procedures including intra-luminal gastrointestinal implants have been proposed to mimic the anatomical, physiological and metabolic changes achieved by these procedures. Many of these designs include long sleeve like elements that prevent contact of food with the walls of the small intestine. It is desirable to have simple delivery systems that can place these implants under endoscopic guidance. However, in order to anchor these sleeve elements safely and reliably, the inventors have previously disclosed anchoring means that anchor the sleeves at the junctions of the stomach and the intestine or the stomach and esophagus.
