1. A drug delivery catheter comprising:
- an elongated body comprising a proximal end and distal end;
a lumen extending along the elongated body to a first infusion section spaced from the proximal end of the elongated body;
one or more openings in the lumen within the first infusion section;
a permeable membrane covering the one or more openings in the first infusion section;
a first tracking element attached to the elongated body at a first selected location proximate the first infusion section to allow a practitioner to determine the position of the first infusion section, wherein the first tracking element comprises an active tracking element comprising a transmitter; and
a second tracking element, wherein the second tracking element is attached to the elongated body at a second selected location, and wherein the second tracking element operates on a different modality than the first tracking element.
