Patent ID: 8123994

Claim:
A method of making a catheter, the method comprising: forming a port joint having a proximal end and a distal end, the port joint including an inflation lumen extending from the proximal end to the distal end of the port joint, the port joint including a guidewire lumen extending from the distal end to a guidewire port located intermediate the proximal end and the distal end of the port joint, the guidewire lumen of the port joint defined by an interior surface of the port joint fully surrounding a periphery of the guidewire lumen; joining a proximal shaft section of the catheter to the proximal end of the port joint such that a lumen of the proximal shaft section is in fluid communication with the inflation lumen of the port joint; and joining a distal shaft section of the catheter to the distal end of the port joint such that a first lumen of the distal shaft section is in fluid communication with the inflation lumen of the port joint and a second lumen of the distal shaft section is in fluid communication with the guidewire lumen of the port joint; wherein the port joint is formed of a material discrete from materials forming the proximal shaft section and the distal shaft section.
