  • Publication number: 20020007158
    Abstract: A body lumen access system comprises a distal access cannula and a proximal access cannula. The distal access cannula is attached to or within the body lumen and the proximal access cannula is attached to an implantable port or is transcutaneously positioned and attached to a luer or other external connector. 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 has a larger lumen diameter than that of the distal access cannula in order to reduce flow resistance within the cannula system. In some cases the distal and proximal access cannulas may be formed integrally.

Preferably, the proximal access cannula has a larger lumen diameter than that of the distal access cannula in order to reduce flow resistance within the cannula system. In some cases the distal and proximal access cannulas may be formed integrally. Replacement of a proximal portion or distal end may be performed by accessing the cannula, removing either the proximal portion or distal end, and reattaching a replacement portion of the cannula.
