Abstract

A body lumen access system (10) comprises a distal access cannula (12) and a proximal access cannula (14). The distal access cannula (12) is attached to or within the body lumen, and the proximal access cannula (14) is attached to an implanted port (24), or is trans-cutaneously positioned and attached to a luer or other external connector (16). The distal and proximal access cannulas are usually implanted separately, cut to length, and attached at a subcutaneous junction location. Preferably, the proximal access cannula (12) has a larger lumen diameter than that of the distal access cannula (12) in order to reduce flow resistance within the cannula system. In some cases the distal and proximal access cannulas may be formed integrally.
