Abstract

See full text

A dual lumen gastrointestinal feeding and aspirating device includes an aspiration channel which carries a feeding channel. The aspiration channel has a distal opening with a larger size than that of the feeding channel so it can operate more effectively as a stent and accommodate larger sized instruments. The distal end of the aspiration channel is repeatably moveable between open and closed conditions in response to the extension and retraction, respectively, of the instrument therethrough.
