    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: Implantable devices are configured to be positioned in or near the heart and to carry and deliver an anti-apoptotic drug to a treatment site in or near the heart. The implantable devices include, but are not limited to, leads, stents, heart valves, atrial septal defect devices, cardiac patches and ventricular restraint devices. Depending on the composition of the device, the drug may be carried by the device through a coating applied to the device, or may be included in the device during the device manufacturing process. The drug may also be included in microparticles, such a microspheres, that are delivered locally through a conduit, such as a catheter.

    摘要: An ultrasonic implantable device includes an ultrasonic sensor having a plurality of transducers. The sensor is configured for mounting to a vessel wall. A first of the transducers directs sound waves in a direction at least partially upstream or downstream in the vessel. A second of the transducers directs sound waves in a radial direction through an interior of the vessel against a sidewall of the vessel. The sensor monitors a change in frequency of the sound waves from the first transducer to determine a fluid velocity in the vessel. The sensor also monitors a reflection time of the sound waves from the second transducer that return from the sidewall to determine an internal diameter of the vessel. The determined fluid velocity and vessel diameter can be used to determine a volumetric flow rate of the fluid in the vessel.
