    摘要: A cardiac rhythm management device is configured to deliver pre-excitation pacing to one or more sites in proximity to an infarcted region of the ventricular myocardium. The pre-excitation pacing in conjunction with counterpulsation therapy serves to either prevent or minimize post-infarct remodeling.

    摘要: A drug delivery system uses an electrically sensitive polymer to store a drug and applies an electric field onto the electrically sensitive polymer for quantitatively and temporally controlled drug delivery. In one embodiment, the drug delivery system is part of a cardiac rhythm management (CRM) system that includes an implantable CRM device and an implantable drug delivery device. The implantable CRM device delivers electrical therapies to a heart and controls the implantable drug delivery device by producing the electrical field with controllable amplitude, frequency, and timing.

    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: Methods, devices, kits and compositions to treat a myocardial infarction. In one embodiment, the method includes the prevention of remodeling of the infarct zone of the ventricle using a combination of therapies. The method may include the introduction of structurally reinforcing agents. In other embodiments, agents may be introduced into a ventricle to increase compliance of the ventricle. The prevention of remodeling may include the prevention of thinning of the ventricular infarct zone. Another embodiment includes the reversing or prevention of ventricular remodeling with electro-stimulatory therapy. The unloading of the stressed myocardium over time effects reversal of undesirable ventricular remodeling. These therapies may be combined with structurally reinforcing therapies. In other embodiments, the structurally reinforcing component may be accompanied by other therapeutic agents. These agents may include but are not limited to pro-fibroblastic and angiogenic agents.
