摘要： A process for reducing solvent contents in drug-containing polymeric compositions may be utilized to reduce the solvent content in implantable medical device wherein the compositions are in reservoirs. Specifically, the solvent contents in the drug-containing polymeric compositions are first reduced by one or more conventional drying methods, to a range from about 0.5 weight percent to about 10 weight percent of the total weight of the polymeric composition. Subsequently, the drug-containing polymeric compositions are further treated by a low temperature drying method for further reduction of the solvent content.

摘要： An expandable medical device includes a plurality of elongated struts, forming a substantially cylindrical device which is expandable from a first diameter to a second diameter. A plurality of different beneficial agents may be loaded into different openings within the struts for delivery to the tissue. For treatment of conditions such as restenosis, different agents are loaded into different openings in the device to address different biological processes involved in restenosis and are delivered at different release kinetics matched to the biological process treated. The different agents may also be used to address different diseases from the same drug delivery device. In addition, anti-thrombotic agents may be affixed to at least a portion of the surfaces of the medical device for the prevention of sub-acute thrombosis. To ensure that the different agents remain affixed to the device as well as to each other, primer layers may be utilized.
