Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current implantable medical devices, such as pacemakers, struggle to effectively monitor and treat cardiac arrhythmias and inefficiencies in heart contractions, as they lack precise mechanisms to adjust therapy parameters based on real-time cardiac activity, particularly the twisting profile of the heart, which is crucial for optimizing pacing and resynchronization therapies.
Innovation Solution
Incorporating a gyroscope into implantable medical devices, like leadless cardiac pacemakers, to sense cardiac twisting profiles and adjust pacing parameters, such as AV delay, VV delay, and pacing vector, based on these profiles, thereby enhancing therapy delivery and monitoring cardiac dysfunction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional implantable medical devices are used without gyroscopes, then the device complexity remains low, but the measurement precision of cardiac twisting profiles is insufficient
Solution Approach 1:
The patent combines a gyroscope sensor with traditional implantable medical device components (housing, electrode, circuitry) to create an integrated system. The gyroscope is disposed within the housing and electrically connected to detect cardiac twisting profiles, merging mechanical sensing capability with existing cardiac monitoring functionality.
Solution Approach 2:
The gyroscope acts as an intermediary sensing mechanism between the cardiac tissue and the device's processing circuitry. It converts mechanical cardiac twisting motions into electrical signals that can be processed to generate twisting profiles, enabling precise measurement without direct mechanical contact with the heart tissue.
2Adaptability or versatility
If pacing parameters are adjusted based on real-time twisting profiles, then the adaptability of therapy delivery is improved, but the device complexity increases
Solution Approach 1:
The system continuously monitors cardiac twisting profiles via the gyroscope and uses this real-time feedback to dynamically adjust pacing parameters. The circuitry receives twisting profile data and modifies pacing parameters accordingly, creating a closed-loop feedback system that adapts therapy delivery to actual cardiac mechanics.
Solution Approach 2:
The patent implements dynamic adjustment of pacing parameters based on real-time cardiac twisting profiles rather than using fixed parameters. The system can modify AV delay, VV delay, and other pacing settings in response to changing cardiac conditions, making the therapy delivery adaptive and responsive.
3Productivity
If multiple pacing parameters are updated based on twisting profiles, then the productivity of therapy optimization is improved, but the loss of time for parameter adjustment increases
Solution Approach 1:
The system continuously monitors and adjusts pacing parameters based on ongoing cardiac twisting profile measurements. Rather than periodic updates, the circuitry continuously optimizes therapy delivery in response to real-time mechanical cardiac data, maintaining continuous useful action throughout the cardiac cycle.
Solution Approach 2:
The system performs preliminary parameter adjustments based on anticipated cardiac conditions by continuously monitoring twisting profiles. This allows the device to proactively optimize pacing parameters before arrhythmias or inefficiencies fully develop, improving productivity through preventive optimization.
