Abstract

The present invention provides delivery systems for positioning a gastrointestinal implant in a patient, for example, for treatment of a metabolic disease. Also provided are methods for assembling the delivery systems, methods of positioning a gastrointestinal implant, and methods of treatment of metabolic diseases, such as type 2 diabetes, non-alcoholic steatohepatitis (NASH), non-alcoholic fatty liver disease (NAFLD), obesity, and related comorbidities thereof.

Claims8

Dependent claims

A delivery system for placing a gastrointestinal implant in a gastrointestinal tract of a patient, the delivery system comprising:

(a) a delivery catheter comprising a lumen;
(b) a container assembly at the distal portion of the delivery catheter, the container assembly comprising a proximal capsule and a distal cap removably attachable thereto;
and
(c) a gastrointestinal implant comprising:
(i) a sleeve configured to carry fluid from its proximal end to its distal end;
and (ii) an anchor connected to the sleeve at or near its proximal end, the anchor configured to secure the proximal end of the sleeve within the gastrointestinal tract;
wherein the gastrointestinal implant is configured to fit within the container assembly such that the anchor fits within the proximal capsule and a portion of the sleeve fits within the distal cap and
wherein the container assembly further comprises an anchor locking mechanism within the proximal capsule.
