摘要： The lead body of a medical lead comprises a distal end portion carrying at least one electrode for placement in the pericardial sac of a human heart. The distal end portion of the lead body includes a multi-turn section having opposed ends, opposing forces applied to the ends tending to flatten the multi-turn section, the multi-turn section being thereby adapted to be retained within the pericardial sac. The turns of the multi-turn section may become progressively smaller from one end of the section to the other end of the section. The multi-turn section may have, in a relaxed state thereof, a generally conical, helical configuration. The at least one electrode may be carried adjacent to the end of the multi-turn section having the larger turns. Alternatively, the at least one electrode may be carried adjacent to the end of the multi-turn section having the smaller turns.

摘要： An implantable lead includes a lead body, having a distal end and a proximal end, configured to be implanted in a patient, and a connector provided at the proximal end. A load detection assembly is provided on the lead body, wherein the load detection assembly includes a housing that holds a sensor and a load transfer element. The load transfer element engages the sensor and conveys a force induced on the load transfer element to the sensor. Optionally, the housing may isolate the sensor from lateral forces and the load transfer element may only convey, to the sensor, longitudinal forces that are directed in a predetermined single direction. For example, the load transfer element may only convey, to the sensor, longitudinal forces that are directed perpendicular to a surface of the sensor.

摘要： An elastic framework configured to be positioned around a portion of the heart has a plurality of first regions and a plurality of second regions positioned relative to the first regions. The framework allows for the positioning of the first regions and second regions adjacent the outer surface of the heart and is structured so that the regions experience different movement effects in response to expansion and contraction of the heart. A sensor network having at least one motion sensor system associated with one of the first regions and second regions is associated with the framework. The motion sensor system outputs data responsive to the relative movement effects of the first and second regions. A communications system in communication with the sensor network provides for the transmission of motion data to a location remote from the framework.
