Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cardiac rhythm management systems do not effectively monitor cardiovascular pressure variations in relation to cardiac pacing, leading to inadequate adjustment of therapy and potential worsening of heart failure symptoms.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cardiovascular pressure monitoring is integrated with cardiac pacing systems, then therapy optimization is improved, but device complexity increases
Solution Approach 1:
The patent combines cardiovascular pressure monitoring and cardiac pacing functions into a single integrated system. The pressure sensor, cardiac cycle detector, and pacing device are merged into one system that can simultaneously monitor physiological parameters and deliver therapeutic pacing, eliminating the need for separate monitoring and treatment devices.
Solution Approach 2:
The implanted medical device is designed to perform multiple functions: it monitors cardiovascular pressure, detects cardiac cycle characteristics, classifies pressure data according to cardiac cycle type, and delivers pacing therapy. This multi-functional approach allows a single device to address both diagnostic and therapeutic needs.
2Reliability
If real-time pressure measurement and therapy adjustment are implemented, then heart failure management is improved, but use of energy increases
Solution Approach 1:
The system performs pressure measurement and therapy adjustment in periodic cycles rather than continuously. The device measures pressure, detects cardiac cycles, and adjusts pacing parameters at specific intervals tied to cardiac cycle events, reducing energy consumption compared to continuous monitoring and adjustment while still providing real-time therapeutic response.
Solution Approach 2:
The device automatically adjusts pacing therapy based on real-time pressure measurements and cardiac cycle detection without requiring external intervention. The system self-regulates by comparing pressure data across different cardiac cycle types and autonomously optimizing pacing parameters, eliminating the need for manual programming or frequent clinical visits.
3Measurement precision
If cardiovascular pressure data is classified by cardiac cycle type, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent segments cardiovascular pressure data according to different cardiac cycle types (e.g., sinus rhythm, atrial fibrillation, paced cycles). By dividing the pressure waveform analysis into distinct segments corresponding to different cardiac cycle characteristics, the system can apply specific measurement and classification algorithms to each segment, improving precision while managing complexity through structured data organization.
