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 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 numerous modifications to the metallic component that are effective to prevent such a substantial reduction in pharmaceutical effectiveness.
Claims15
An injection catheter for delivery of a pharmaceutically active material, said injection catheter comprising:
- a metallic lumen, said metallic lumen acting to substantially reduce pharmaceutical effectiveness of said pharmaceutically active material upon contact;
- wherein said metallic lumen is further provided with a layer of polymeric material that comprises a polymer selected from a silicone polymer, a polypropylene, and a polyether block amide such that said substantial reduction in the pharmaceutical effectiveness of the pharmaceutically active material is decreased.
