    摘要: The present invention provides systems and methods for the targeted delivery of a therapeutic agent using expandable devices that are temporarily or permanently placed within the body. Such therapeutic agents may be delivered as a coating on the outer surface of the expandable device. Once positioned at a desired location within the body, the device is expanded such that its drug-coated outer surface establishes direct contact with a target tissue. The expanded device remains in contact with the target tissue for a pre-determined amount of time prior to being withdrawn from the body. Delivery of the therapeutic agent using the expandable device may be followed, or preceded, by delivery of a second expandable device to the same location within the body.

    摘要: A medical device includes a carrier and an agent. The agent is formulated to control inflammation of biological tissue, such as heart tissue, and is releasably coupled to the carrier. The carrier is configured to be disposed in operative proximity to the biological tissue to be treated by the agent. In one embodiment, the carrier is configured to release the agent or otherwise deliver the agent to the biological tissue, thus controlling inflammation of the tissue. Also, a method to improve healing of biological tissue includes placing a medical device proximate to the heart of a patient, where the medical device has a carrier and an agent configured to control inflammation, the agent is releasably coupled to the carrier. In one embodiment, the method includes causing the agent to be released from the carrier.

    摘要: This invention relates to a method of treating ischemic or diseased myocardium by injecting a therapeutic agent, such as a gene, protein, cell or drug, into normal myocardium, preferably adjacent to an ischemic zone in the heart of a subject. The method is useful for inducing angiogenesis and collateral blood vessel formation to improve cardiac function in subjects with ischemic heart disease. The method can also be used to promote tissue regeneration in such subjects.
