Abstract
A system for inducing weight loss in a patient, includes (a) an elongated element extending from a proximal end to a distal end, the elongated element separating a duodenum into first and second channels, wherein the elongated element is expandable; and (b) a retainer connected to the elongated element and securing the elongated element in a desired orientation within the duodenum. In the desired orientation, all chyme flowing through the duodenum enters the first channel and the second channel is open to a papilla of vater so that digestive fluids from the papilla of vater enter the second channel.
Claims10
A method for inducing weight loss in a patient, comprising:
- inserting an elongated element to a desired position within a duodenum with an outer surface of the elongated element contacting an inner surface of the duodenum to separate the duodenum into first and second longitudinal channels, the elongated element extending from a proximal end to a distal end, the elongated element being positioned so that all chyme flowing through the duodenum enters the first channel and the second channel is open to a papilla of vater so that digestive fluids from the papilla of vater enter the second channel, wherein the elongated element is expandable;
- connecting the elongated element to the duodenum using a retainer.

- inserting a funnel into the duodenum so a proximal end thereof is positioned proximally of a pylorus and a distal end thereof is open to the first longitudinal channel to guide a flow of chyme thereinto, a diameter of the proximal end of the funnel being greater than a diameter of the pylorus.
