STENT DRUG DELIVERY SYSTEM

摘要

Expandable intraluminal stents are provided as well as their method of manufacture. These stents are made of metal or polymer, the material characterized by a desired porosity, with a drug compressed into the pores of the stent. The stents are formed by subjecting one or more powdered materials in a die cavity to a pressure treatment followed by a heat treatment. The metal may be cast directly in a stent-like form or cast into sheets or tubes from which the inventive stents are produced. The so-formed porous metal stent is then loaded with one or more drugs.
