STENT WITH DRUG COATING WITH VARIABLE RELEASE RATE |
摘要 |
A stent is provided with a coating having a variable drug release rate. The release rate can be greater over a curved or bent segment of a strut network as compared to generally linear segments of the strut network. The coating can have a barrier region that is thicker over the generally linear segments. The coating can have a drug mixed with polymers. The curved or bent segment can have a greater amount of a polymer having relatively high drug permeability as compared to the generally linear segments.
