An endoprosthesis, e.g., a stent (e.g., a drug eluting stent), includes a surface, a first layer having a polyelectrolyte deposited on the surface, a plurality of polymeric particles deposited on the first layer, and a coating of a porous material deposited on the plurality of polymeric particles. At least one particle of the plurality of polymeric particles includes a polymer matrix and a drug distributed in the polymer matrix. A method of making the endoprosthesis is also disclosed. |
