    摘要: Medical devices, and in particular implantable medical devices, may be coated to minimize or substantially eliminate a biological organism's reaction to the introduction of the medical device to the organism. The medical devices may be coated with any number of biocompatible materials. Therapeutic drugs, agents or compounds may be mixed with the biocompatible materials and affixed to at least a portion of the medical device. These therapeutic agents or compounds may also further reduce a biological organism's reaction to the introduction of the medical device to the organism. In addition, these therapeutic drugs, agents and/or compounds may be utilized to promote healing, including the prevention of thrombosis. The drugs, agents, and/or compounds may also be utilized to treat specific disorders, including vulnerable plaque, and atherosclerosis in type 2 diabetic patients. Therapeutic agents may also be delivered to the region of a disease site. In regional delivery, liquid formulations may be desirable to increase the efficacy and deliverability of the particular drug. Various materials and coating methodologies may be utilized to maintain the agents or compounds on the medical device until delivered and positioned.

    摘要: A drug delivery balloon is provided, the a balloon having an outer surface, and a tunable coating disposed on at least a length of the balloon surface. The tunable coating includes a first therapeutic agent and a first excipient, and a second therapeutic agent and a second excipient. The first and second therapeutic agents have different dissolution rates during balloon inflation and therefore provide a coating that is tunable.

    摘要: The present disclosure comprises a polymeric substrate that provides multiple releases of active agents. A substrate for multiple phase delivery of active agents is provided having a first polymer matrix layer having a first active agent disposed therein, a second polymer matrix layer having a second active agent disposed therein, and a coacervate layer disposed between the first polymer matrix layer and the second polymer matrix layer. Selected first and second active agents are included in the first and second polymer matrices such that as the first and second polymer matrices dissolve, the active agents are released. Multiple phase active agent release is achieved by constructing multiple layers of a polymer matrix containing an active agents formed with polymers having different solubility characteristics or with active agents at different concentration levels.
