主权项

1. A catheter, comprising:
a first conduit; a second conduit communicating with the first conduit; wherein the catheter defines a longitudinal axis, and portions of the first conduit establish axially longer segments and axially shorter segments and wherein portions of the second conduit establish axially longer segments and axially shorter segments, the axially shorter segments being axially shorter segments and the axially longer segments being axially longer segments in that the axially shorter segments are shorter in the dimension defined by the longitudinal axis than the axially longer segments, and further wherein at least one of the axially shorter segments of the second conduit extends axially between first and second transverse segments associated with at least one of the axially longer segments of the first conduit, at least one axially shorter segment of the first conduit being oriented parallel to the longitudinal axis.
