1. A duodenal/small intestinal insert comprising:
- an elongated member configured to be placed in the duodenum, wherein the elongated member has a proximal end, a distal end, and a longitudinal axis extending from the proximal end to the distal end;
a sleeve positioned around the elongated member, the sleeve slideable along the longitudinal axis to transition the sleeve from a stowed configuration wherein the sleeve is substantially axially aligned with the longitudinal axis to a deployed configuration wherein at least one portion of the sleeve expands away from the longitudinal axis at a predefined location to form a flow reduction element; and
an anchor connected to the proximal end of the elongated member and separated from the sleeve, wherein the anchor is configured to be placed in an antrum to anchor the sleeve in the duodenum.

18. A duodenal/small intestinal insert comprising:
-
an elongated solid shaft member having a longitudinal axis configured to conform to the duodenum; a sleeve positioned around the elongated solid shaft member, the sleeve moveable along the longitudinal axis of the elongated solid shaft member to cause the sleeve to expand at a plurality of predefined locations to form a plurality of flow reduction elements spaced apart along the longitudinal axis; and an anchor connected to a proximal end of the elongated solid shaft member and separated from the sleeve, wherein the anchor is configured to be placed in an antrum to anchor the sleeve in the duodenum.

19. A method of reducing flow of chime through a duodenum, comprising:
-
advancing a flow reducing device in a stowed condition into a duodenum of a patient, the flow reducing device including an elongated member and a sleeve positioned around the elongated member; placing an anchor in an antrum, wherein the anchor is connected to a proximal end of the elongated member and separated from the sleeve, so as to anchor the sleeve in the duodenum; and sliding a sleeve along a longitudinal axis of the elongated member, the longitudinal axis extending from the proximal end of the elongated member to a distal end of the elongated member, so as to transition the sleeve from a stowed configuration wherein the sleeve is substantially axially aligned with a longitudinal axis of the elongated member to a deployed configuration wherein at least one portion of the sleeve expands away from the longitudinal axis at a predefined location to form a flow reduction element. - View Dependent Claims (20)
