    摘要: 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.

    摘要: Medical balloons and/or catheters are disclosed that include a wall that includes a composite material. The composite material includes a polymeric material and particles that include an allotrope of carbon. In some instances, at least some of the particles are covalently bonded to the polymeric material. Methods for making such medical balloons and/or catheters are also disclosed.
