Implantable Monitoring Device for Cardiovascular Anomaly Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitoring devices for predicting cardiovascular anomalies, such as cardiac decompensation, have low specificity and provide false alarms due to their reliance on single physiological parameters, leading to late warnings or missed alarms, as they fail to account for the body's compensation mechanisms and varied reactions to disturbances.
Innovation Solution
A monitoring device that acquires and analyzes changes in both physiological and state parameters, using a transformation unit to create a characteristic variable based on the chronological correlation and absolute value of these changes, allowing for early and specific prediction of cardiovascular anomalies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple parameters are monitored to improve prediction accuracy, then measurement precision improves, but device complexity increases
Solution Approach 1:
The patent combines multiple monitoring functions (physiological parameter monitoring, state parameter monitoring, analysis, transformation, and prediction) into a single integrated implantable device. This merging approach enables comprehensive multi-parameter monitoring while maintaining a compact form factor, resolving the contradiction between measurement precision and device complexity.
Solution Approach 2:
The implantable device is designed with multi-functionality, serving as both a monitoring device and potentially an electrotherapy device. It can monitor multiple physiological parameters and state parameters simultaneously, perform complex analyses, and provide predictions, all within a single universal platform, thereby improving prediction accuracy without proportionally increasing complexity.
2Ease of operation
If single physiological parameter is monitored to simplify device operation, then ease of operation improves, but reliability deteriorates due to false alarms
Solution Approach 1:
The device incorporates feedback mechanisms where the analysis unit continuously processes both physiological and state parameters, and the prediction unit uses this processed information to generate predictions. This feedback loop enables the system to distinguish between normal variations and true anomaly indicators, maintaining ease of operation while significantly improving reliability and reducing false alarms.
Solution Approach 2:
The patent uses a composite approach by combining information from multiple parameter types (physiological parameters and state parameters) to create a more reliable prediction signal. This composite information processing allows the device to maintain simple operation while achieving high specificity through the synergistic combination of multiple data sources.
3Measurement precision
If long-term averaging is used to represent healthy state to improve reliability, then measurement precision improves, but loss of time increases
Solution Approach 1:
The device performs preliminary action by continuously collecting and pre-processing both physiological and state parameter data in real-time. The analysis unit and transformation unit prepare the data beforehand, so when an anomaly occurs, the prediction unit can quickly generate accurate predictions without needing to perform lengthy post-processing calculations, thus improving both precision and response time.
Solution Approach 2:
The system dynamically adjusts its processing based on the incoming data stream. Rather than using fixed long-term averaging, the device continuously updates its understanding of the healthy state by integrating both physiological and state parameters in real-time, allowing it to maintain measurement precision while responding quickly to changes in the patient's condition.

AI summary
A monitoring device for a patient for predicting a cardiovascular anomaly and a method for operating a monitoring device is provided. Furthermore, an implantable electrotherapy device, such as an implantable cardiac pacemaker, an implantable cardioverter, or an implantable defibrillator, having a monitoring device are also provided. In an embodiment, the monitoring device acquires a value change of a hemodynamic parameter, which occurs as a result of a detected value change of a state parameter, for example, as a result of an activation or deactivation of a cardiac resynchronization therapy. By suitable evaluation of the value change of the hemodynamic parameter, the monitoring device can output an evaluation result signal which is indicative of an imminence of a cardiovascular anomaly, such as a cardiac decompensation, long beforehand and with high specificity.
