1. A method of manufacturing a multi-lumen catheter, the method comprising:
extruding a catheter body having a first lumen and at least one additional lumen, the catheter body being formed of a first material having a first melting temperature;
providing a second material on an inner surface of the first lumen, the second material having a melting temperature greater than the first material;
directing a fluid through the at least one additional lumen to move the first lumen to a collapsed configuration;
melting the first material without melting the second material while the first lumen is in the collapsed configuration; and
cooling the first material to allow the first material to set with the first lumen in the collapsed configuration,
wherein after cooling the first material, the first lumen is configured to receive a guidewire, and
wherein to receive the guidewire, the first lumen is configured to expand.
