Abstract
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.
Claims20
A method, comprising:
- inserting a dual lumen device into a patient, the dual lumen device including a first tube which carries a second tube, the first tube having a larger sized distal opening than the second tube;
- and
- moving an instrument through the first tube, wherein the distal opening of the first tube moves between deployed and collapsed conditions in response to movement of the instrument.
A method, comprising:
- providing a dual lumen device, the dual lumen device including an aspiration tube which carries a feeding tube, wherein the aspiration tube includes a window positioned proximate to its distal end;
- inserting the dual lumen device into a patient;
- and
- moving an instrument through the aspiration tube, wherein the window moves between deployed and collapsed conditions in response to movement of the instrument.

A method, comprising:
- providing a dual lumen device, the dual lumen device including an aspiration and feeding tube;
- inserting the dual lumen device into a patient;
- and
- moving an instrument through the aspiration tube, a distal opening of the aspiration tube moving between open and closed conditions in response to movement of the instrument, wherein the instrument has a dimension which prevents it from extending through a distal opening of the feeding tube.
