    摘要: Methods of highly selective cardiac tissue stimulation and devices for practicing the same, e.g., implantable segmented electrode devices, are provided. The methods and devices provide a previously unavailable high phrenic nerve capture voltage paired with a low pacing capture voltage threshold. The subject methods and devices provide a number of benefits. For example, patients who previously would have been required to have their resynchronization device turned off due to phrenic nerve capture will now be able to reap the benefits of resynchronization therapy.

    摘要: Minimally invasive deployable epicardial array devices are provided. The devices include deployable platform comprising two or more effectors, such as sensors and actuators, where the devices are configured to be deployed at an epicardial location via a minimally invasive, e.g., sub-xiphoid approach. In embodiments of the present invention, at least one area of the electrode patch is an electrical control area that comprises a series of effectors, e.g., sensors and/or electrodes. Other embodiments provide localized physical constraint and dynamic mechanical stimulation of the heart to effectuate physical and biological responses. Still other embodiments provide both of these functions. Also provided are methods of using the devices, as well as systems and kits that include the devices.

    摘要: Methods for evaluating motion of a tissue, such as of a cardiac location, e.g., heart wall, via continuous field tomography are provided. In the subject methods, a continuous field (e.g., an electrical, mechanical, electro-mechanical, or other field) sensing element is stably associated with the tissue location. A property of the applied continuous field is detected with the sensing element to evaluate movement of the tissue location. Also provided are systems, devices and related compositions for practicing the subject methods. The subject methods and devices find use in a variety of different applications, including cardiac resynchronization therapy.
