Gastrointestinal Device

A gastrointestinal device for reducing flow through a pyloric sphincter of a patient, comprising:

• a stent including a plurality of strands forming first and seconds ends, the plurality of strands configured to move between a retrieval configuration, wherein the plurality of strands are substantially parallel, and a deployed configuration, wherein the plurality of strands form a proximal portion having a first diameter and a distal portion having a second diameter, the first and second diameters being larger than a diameter of the pyloric sphincter;
• a connector assembly including a proximal connector, a middle connector, and a distal connector, the middle connector coupled to the proximal connector and the distal connector when the plurality of strands are in the deployed configuration and the plurality of strands being attached at the first end to the proximal connector and at the second end to the distal connector;
• a release mechanism attached to the proximal connector and configured to decouple the proximal connector from the middle connector, wherein decoupling of the proximal and middle connectors allows the plurality of strands to move from the deployed configuration to the retrieval configuration.
