Proximally seperable catheters and associated methods

A method of placing a catheter system, comprising:

• providing a catheter including a body formed of a first material and defining a first lumen and a second lumen, and including a septum formed of a second material and disposed laterally between the first lumen and the second lumen, the first lumen and the second lumen defining an equivalent length from a longitudinal mid-point;
• creating a subcutaneous pocket in a patient;
• advancing a distal end of the first lumen to a first destination and a distal end of the second lumen to a second destination;
• separating a proximal portion of the first lumen from a proximal portion of the second lumen by urging a wire, formed of a third material, transversely through the septum to separate the proximal portion of the first lumen from the proximal portion of the second lumen;
• trimming the first lumen to a first length, and trimming the second lumen to a second length, different from the first length;
• and
• coupling a first access device to the first lumen and a second access device to the second lumen, the first access device and the second access device disposed in a spaced apart relationship within the subcutaneous pocket.
