1. A method of making a multi-lumen catheter, comprising:
- providing an assembly comprising;
a proximal catheter body substrate comprising an outer wall and a septum, the outer wall and the septum defining first and second lumens, the septum comprising a proximal region and a distal region;
a first distal catheter body substrate comprising a third lumen shaped substantially similar to the first lumen;
a second distal catheter body substrate comprising a fourth lumen shaped substantially similar to the second lumen;
a first mandrel and a second mandrel inserted respectively through the first lumen and the second lumen, and into at least a portion of the third lumen and fourth lumen, the first distal catheter body substrate and second distal catheter body substrate placed in abutting relationship with the proximal catheter body substrate;
a reinforcing element positioned over the proximal catheter body substrate and at least a proximal region of the first and second distal catheter body substrates;
a sleeve positioned over the reinforcing element;
shrink tubing positioned over the sleeve;
heating the assembly; and
removing the shrink tubing.
