Abstract: Implantable medical devices having anti-restenotic coatings are disclosed. Specifically, implantable medical devices having coatings of certain anti-inflammatory agents, are disclosed. The anti-inflammatory agents are selected from the group consisting of Sanglifehrin A, Sanglifehrin B, Sanglifehrin C, Sanglifehrin D, and pharmaceutically acceptable derivatives thereof. The anti-restenotic medical devices include stents, catheters, micro-particles, probes and vascular grafts. Intravascular stents are preferred medical devices. The medical devices can be coated using any method known in the art including compounding the anti-inflammatory agent with a biocompatible polymer prior to applying the coating. Moreover, medical devices composed entirely of biocompatible polymer-anti-inflammatory agent blends are disclosed. Additionally, medical devices having a coating comprising at least one anti-inflammatory agent in combination with at least one additional therapeutic agent are also disclosed.

Abstract: Methods, systems and devices for delivering a diagnostic or therapeutic treatment, substance or device to a target area located within the body of a human or animal subject. A tissue penetrating catheter is positioned within a body lumen near the target area. A hollow penetrator is then advanced from the tissue penetrating catheter and penetrated from the body lumen in which the penetrating catheter is positioned into tissue in the direction of the target area. Thereafter, an elongate optical device (e.g., an optically equipped guidewire or catheter) is advanced through the hollow penetrator and continues to advance through tissue, in the direction of the target area. The elongate optical device is connected to an optical processing device (e.g., a spectrometer) which provides optically determined data (e.g., spectral reflectance, pH, oxygen concentration, temperature) indicating when the elongate optical device has entered the target area.

Abstract: The present invention relates to methods, kits, and compositions for safe and efficient delivery of a bioagent to a targeted area of an organ. The method comprises preparing a suspension comprising the bioagent, a contrast agent, and a vehicle, wherein said suspension has an osmolarity from about 270 mOsm to about 440 mOsm; and dispensing at least a portion of said suspension into the targeted area. The invention further provides a kit for delivering a bioagent into a targeted area of an organ comprising: a delivery device; a contrast agent; and a vehicle.

Abstract: Medical devices and related methods for making and using same suitable for treating or inhibiting restenosis are proved. Specifically, compositions and methods for I kappa B alpha (IkB?)nuclear factor k? (NFk?) complex breakdown inhibition are provided. One embodiment includes a CRM-1 protein binding composition such as leptomycin B. Another embodiment includes a combination of a CRM-1 protein binding composition and a nucleic acid encoding for mammalian IkB?. Medical devices disclosed include catheters and vascular stents.

Abstract: The disclosure is directed to apparatus and techniques that deliver an active agent, such as an antibiotic age nt or loosening agent to a patient by diffusion. An element of the medical device deployed proximate to the cells or host tissue includes a diffusible material, which comprises a lumen. An agent introduced into the lumen diffuses through the diffusible material to the cells or host tissue or tissues. The invention can be applied to medical devices that are placed partially inside a patient, as well as those that are fully implanted. Some embodiments support moving the internal element of a medical device proximate to targeted cells, such as a tumor, and administering an active agent to the targeted cells by diffusion. The disclosure also encompasses a testing system that helps test and develop apparatus and techniques for delivering an agent by diffusion.
