    摘要: Catheter devices having an expandable balloon for delivering a therapeutic agent to a body site. In one aspect, one or more sheaths are disposed around the balloon with the therapeutic agent being disposed within the sheath, being disposed over the sheath, being contained in the space between the sheath and the balloon, or being otherwise associated with the sheath. In another aspect, the balloon includes a micro-electromechanical system (MEMS) for drug delivery.

    摘要: Catheter devices having an expandable balloon for delivering a therapeutic agent to a body site. The balloon has one or more folds which serve as a reservoir for containing the therapeutic agent. The fold may have any of various configurations to hold the therapeutic agent. In some cases, the balloon comprises one or more lobes that forms the fold(s). The therapeutic agent may be provided in various ways. For example, the therapeutic agent may be contained in packets that rupture upon expansion of the balloon, or as a plurality of discrete bulk masses, or sealed within compartments.

    摘要: Medical devices, such as stents, having a surface, a coating layer comprising a polymer disposed on at least a portion of the surface, and a composition comprising a biologically active material injected into or under the coating layer at one or more locations in the coating layer to form at least one pocket containing a biologically active material are disclosed. The composition may be injected using a nanometer- or micrometer-sized needle. Methods for making such medical devices are also disclosed. Using this method, a precise amount of the biologically active material may be disposed accurately and efficiently on the medical device at predefined locations.
