Patent ID: 7662328

Claim:
A method of making a catheter, the catheter including a proximal member defining a first lumen and a distal member defining a second lumen and a guidewire lumen, the method comprising: providing a mold; injecting molding material into the mold to mold a port joint having a proximal portion and a distal portion from the molding material, the molding material forming the port joint being discrete from material of the proximal member and material of the distal member; joining the proximal member to the distal member with the port joint such that the proximal member is longitudinally spaced from the distal member by the port joint, the port joint adapted to couple the first lumen to the second lumen and including a guidewire port for directing a guidewire from outside the catheter into the guidewire lumen; wherein: the distal member includes a first tubular member and a second tubular member; and the method further comprises the step of coupling the first tubular member to the mold such that, when the port joint is molded, the first tubular member becomes attached to the port joint, and the distal portion of the port joint is at least partially disposed within the first tubular member.
