摘要:
One embodiment of the present invention provides a system for automatically optimizing CRT procedures using a multi-electrode pacing lead. During operation, the system performs a first set of iterations to select one or more satellites on one or more pacing leads inserted in a patient. A pacing lead includes a plurality of pacing satellites, and a pacing satellite includes a plurality of electrodes that can be individually addressed and used for transmitting or detecting electric signals. The system then performs a second set of iterations to select one or more electrodes on the selected satellites. The system further performs a third set of iterations to select one or more timing configurations for pacing signals transmitted through one or more of the selected electrodes.

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.

Implantable devices for evaluating body-associated fluid transport structures and methods for using the same are provided. In some instances, the implantable devices include an elongated structure with at least one hermetically sealed integrated circuit sensor stably associated therewith and a transmitter. The devices find use in a variety of different applications, including monitoring the function of various types of body-associated fluid transport structures, such as arteriovenous fistulae, vascular grafts, catheters, cerebrospinal fluid shunts, and implantable central venous access devices.

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.
