Claim 19:
20. A catheter comprising:
a body structure extending from a proximal body end to a distal body end;
a passageway extending within the body structure and along a passageway portion of a length of the body structure from a proximal passageway end to a distal passageway end;
at least one proximal passageway opening passing through the body structure near the proximal body end for fluidly coupling an ambient environment of the body structure with the passageway;
a plurality of distal passageway openings, wherein:
each distal passageway opening of the plurality of distal passageway openings passing through the body structure near the distal body end for fluidly coupling the ambient environment of the body structure with the passageway; and
the plurality of distal passageway openings comprises:
a first distal passageway opening;
a second distal passageway opening positioned between the distal body end and the first distal passageway opening; and
a third distal passageway opening positioned between the distal body end and the second distal passageway opening;

a lumen extending within the body structure and along a lumen portion of the length of the body structure from a proximal lumen end to a distal lumen end, wherein the lumen is distinct from the passageway within the body structure along a shared portion of the length of the body structure from a proximal shared portion end to a distal shared portion end; and
at least one proximal lumen opening passing through the body structure near the proximal body end for fluidly coupling the ambient environment of the body structure with the lumen, wherein:
at least one of the plurality of distal passageway openings fluidly couples the ambient environment of the body structure with the lumen; and
the shared portion of the length of the body structure extends at least between:
the most distal of the at least one proximal passageway opening and the at least one proximal lumen opening; and
the most proximal of the plurality of distal passageway openings.
