    摘要: A drug delivery system detects a cardiac condition indicative of a need for increasing a cardiac metabolic level and, in response, releases a drug into tissue or blood to shift a source of metabolically synthesized energy fueling cardiac contraction from fatty acid to glucose. One example of such a system includes an implantable device detecting an ischemia and a transdermal drug delivery device delivering a drug when an ischemic condition is detected. Another example of such a system includes one or more implantable devices detecting a predefined change in cardiac metabolic level and delivering a drug when the change is detected. Such systems are applied to treat, for example, patients suffering ischemia and/or heart failure and patients having suffered myocardial infarction.

    摘要: A system delivers combined ventricular assist device (VAD) therapy and chemical and/or biological therapy to modulate myocardial tissue growth in a heart after myocardial infarction (MI). The system includes an agent delivery device to release one or more agents to an MI region to modulate myocardial tissue growth in that region, and a VAD to enhance the effects of the one or more agents by reducing myocardial wall stress and the overall cardiac workload. In one embodiment, the system is an implantable system including an implantable agent delivery device and an implantable VAD for long-term use in a patient.
