1. An apparatus, comprising:
- a tubular member configured to be inserted into a gastrointestinal lumen defined by a colon, the tubular member defining a first conduit and a second conduit;
a first expandable member coupled to the tubular member in fluid communication with the first conduit; and
a second expandable member coupled to the tubular member in fluid communication with the first conduit,the first expandable member and the second expandable member configured to sealingly engage a first portion of the colon when the first expandable member and the second expandable member are each in an expanded configuration to define a volume bounded by a portion of the first expandable member, a portion of the second expandable member and a second portion of the colon, the volume in fluid communication with the second conduit, the second portion of the colon opposite at least a portion of the first portion of the colon.

Abstract
An embodiment of the invention includes inserting into a gastrointestinal lumen, a catheter having a first balloon and a second balloon spaced from the first balloon. The first balloon and the second balloon are inflated to sealingly engage the lumen. A liquid is introduced into a volume bounded by the first balloon, the second balloon and the lumen so that the liquid contacts at least a portion of the lumen.
