A balloon catheter including a dedicated contrast fluid lumen is disclosed. The contrast fluid lumen extends through the catheter shaft to a contrast fluid delivery port located proximate the inflatable balloon and is configured to deliver contrast fluid to a target location. The catheter shaft includes a joint located proximate the contrast fluid port formed between a distal end of a proximal outer tubular member, a distal end of an inner tubular member and a proximal end of a distal outer tubular member. A guidewire tube, defining a guidewire lumen, may extend through the lumen of the proximal and distal outer tubular members.
