Abstract
A modified medical device for delivery of a pharmaceutically active material is described. The present inventors have found that many conventional medical devices contain a metallic or polymeric component that comes into contact with a pharmaceutically active material during use, and that the contact substantially reduce the pharmaceutical effectiveness of the pharmaceutically active material. The invention described herein concerns various modifications to the metallic or polymeric component that are effective to diminish such a substantial reduction in pharmaceutical effectiveness.

A modified medical device for delivery of a pharmaceutically active material comprising:
- a catheter comprising an incompatible metallic delivery lumen which acts to substantially reduce pharmaceutical effectiveness of said pharmaceutically active material upon contact with said pharmaceutically active material;
- wherein said incompatible metallic delivery lumen is modified by providing it with a layer of polymeric material such that said substantial reduction in the pharmaceutical effectiveness or the pharmaceutically active material is diminished upon contact with said drug delivery lumen.
