1. A medical device, comprising:
a tube having a distal end, a proximal end, a port located proximal of the distal end, and a length of the tube extending between the proximal end and the distal end, wherein a first portion of the tube is proximal of the port and has a first cross-sectional area and a second portion of the tube is distal of the port and has a second cross-sectional area smaller than the first cross-sectional area;
a first lumen extending from the proximal end to the distal end of the tube and having a distal opening on a distalmost face of the distal end of the tube;
a second lumen in communication with the port and fluidly connecting the proximal end of the tube with the port; and
a laser fiber disposed within the first lumen, the laser fiber configured to extend distally from the distalmost face of the distal end of the tube through the distal opening,
wherein the first cross-sectional area includes a cross-section of only one additional lumen than the second cross-sectional area,
wherein the first portion of the tube defines an outermost wall of each of the first lumen and the second lumen, and
wherein a position of the first lumen is fixed relative to a position of the second lumen.
