STENT AND MANUFACTURING METHOD THEREOF

摘要

Provided are a stent and a method for manufacturing the same. On the stent is formed a protective metal layer which ensures the mechanical stability that the outermost biocompatible metal oxide layer containing pores therein does not fall off the stent frame even after expansion and contraction. Treated with plasma, the stent can release a drug loaded into the pores in a delayed pattern for a prolonged period of time.
