Enhanced Electrode Combination Selection for Cardiac Pacing

An optimized system for selecting electrode combinations in cardiac pacing devices, ensuring efficient and safe delivery of pacing stimuli while minimizing phrenic nerve activation.

The original patent relates to the selection of electrode combinations in cardiac pacing devices. However, it has limitations in terms of adaptability, real-time optimization, and personalized electrode configuration selection. The new inventive concept addresses these limitations by introducing real-time monitoring, adaptive pacing, and personalized selection of electrode configurations to minimize phrenic nerve activation while maintaining optimal cardiac function.

The new inventive concept consists of a system that analyzes cardiac tissue capture thresholds for multiple electrode configurations and selects an optimal configuration based on a predetermined set of criteria. The system includes a processor, a sensor, and a graphical user interface. The processor is configured to monitor cardiac tissue capture thresholds in real-time, adjust pacing stimuli amplitude and/or electrode configuration accordingly, and select an optimal electrode configuration based on the analyzed data. The sensor detects cardiac tissue capture thresholds, and the graphical user interface enables user input for personalized electrode configuration selection. The system can be implemented in various embodiments, including a standalone device, an implantable device, or a networked system.

The new inventive concept introduces the novel feature of real-time monitoring and adaptive pacing, which is not present in the original patent. The inventive step lies in the combination of real-time monitoring, personalized electrode configuration selection, and adaptive pacing to minimize phrenic nerve activation while maintaining optimal cardiac function.

Alternative embodiments of the inventive concept may include variations in the type of sensor used, the algorithm for analyzing cardiac tissue capture thresholds, or the graphical user interface design. Additionally, the system could be integrated with other cardiac devices or systems, such as ECG monitors or cardiac resynchronization therapy devices.

The enhanced electrode combination selection system has significant commercial potential in the cardiac pacing device market, particularly in the areas of cardiac resynchronization therapy and implantable cardioverter-defibrillators. The system's ability to minimize phrenic nerve activation while maintaining optimal cardiac function could lead to improved patient outcomes and reduced healthcare costs.
