Methods and devices for delivering or delaying lipids within a duodenum

Abstract

Devices and methods described include a flow reduction device adapted and configured for use within the duodenum of a mammal having a spine, a first atraumatic feature, a second atraumatic feature, and a flow reduction element having a proximal end, a distal end, an interior portion, an exterior portion and a variable porosity between the proximal end and the distal end. One aspect of the device includes a spine having a proximal end and a distal end, an atraumatic feature positioned on at least one of the proximal end and the distal end of the spine, and a flow reduction element positioned along the spine and having a variable porosity along its length.

What is claimed is: 
     
         1 . A device adapted and configured for use within the duodenum of a mammal, comprising:
 a spine having a proximal end and a distal end;   an atraumatic feature positioned on at least one of the proximal end and the distal end of the spine; and   a flow reduction element positioned along the spine and having a variable porosity along its length.
