1. An infusion catheter comprising:
a shaft comprising a proximal section, a distal section, and an intermediate section therebetween;
a first lumen and a second lumen extending along a length of the shaft; and
an inflatable member provided distally to the intermediate section, and over the distal section;
wherein the first lumen has a cross section larger than a cross section of the second lumen and is configured to receive a guidewire therethrough and to allow fluid flow via an unobstructed portion of the first lumen,
wherein the unobstructed portion is formed along an outer surface of the guidewire, between the outer surface of the guidewire and an inner wall of the first lumen, and extends from an infusion inlet at a proximal end of the intermediate section to an infusion outlet at a distal end of the intermediate section;
wherein the first lumen is narrowed to approximate a first diameter in the proximal section and along an entire length of the distal section, and is widened to approximate a second diameter greater than the first diameter in the intermediate section, and
wherein the infusion inlet is located in a proximal connector that is configured to allow selective introduction of a fluid into the first lumen.
