    摘要: A method of making a therapeutic composition, as well as the therapeutic composition so made, is disclosed. The method comprises mixing a hydrophobic drug with an aqueous buffer solution and adding a surfactant to the aqueous buffer solution to form the therapeutic composition. A implantable medical device with the therapeutic composition and a method of making a coating for an implantable medical device containing the therapeutic composition is also disclosed.

    摘要: A drug-loaded microparticle is applied to a medical device for subsequent application to biological tissues. A method of formulating a drug-loaded microparticle and applying it to the surface of a medical device, such as a stent, is disclosed. The drug-loaded microparticle is formulated by combining a drug with various chemical solutions. Specified sizes of the microparticles and amounts of drug(s) contained within the microparticles may be varied by altering the proportions of the chemicals/solutions. In addition to various drugs, therapeutic substances and radioactive isotopes may also be loaded into the microparticles. The drug-loaded microparticle are suspended in a polymer solution forming a polymer matrix. The polymer matrix may be applied to the entire surface or only selected portions of the medical device via dipping, spraying or combinations thereof.
