1. A medical device comprising:
a tube extending from a proximal end to a distal end and including a port proximal to the distal end, wherein a first section of the tube proximal of the port has a first cross-sectional area and a second section of the tube distal of the port 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 terminating at a distal opening, wherein the distal opening is at a fixed distance from the port;
a second lumen in communication with the port and fluidly connecting the proximal end of the tube with the port, wherein the second lumen extends adjacent to the first lumen in the first section of the tube;
an imaging device at the distal end of the tube, wherein the imaging device is configured to receive power from connecting wires extending within a wall of the tube between the first lumen and the second lumen; and
a laser fiber disposed within the first lumen and movable distally through the distal opening.
