Dual-anchor sensor implant for cardiac pressure monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical technologies face challenges in effectively monitoring cardiac pressure parameters, particularly in the left atrium, which is crucial for early detection and prevention of congestive heart failure, due to invasive methods and unreliable surrogate measurements.
Innovation Solution
A dual-anchor sensor implant device with opposing helical tissue anchors and a sensor transducer system that securely anchors into cardiac tissue, allowing for direct monitoring of cardiac pressure through wireless transmission of data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If invasive methods are used to monitor cardiac pressure, then direct measurements can be obtained, but patient risk and procedural complexity increase
Solution Approach 1:
The patent replaces traditional invasive mechanical catheter-based pressure monitoring with a minimally invasive implantable sensor device that uses electrical and electronic systems to measure cardiac pressure directly, thereby maintaining measurement precision while significantly reducing patient risk and procedural complexity
Solution Approach 2:
The patent introduces an implantable sensor device as an intermediary between the cardiac chamber and external monitoring systems, allowing direct pressure measurement within the heart while avoiding the need for repeated invasive catheter procedures, thus reducing overall patient risk
2Device complexity
If single-anchor sensor implants are used, then device simplicity is maintained, but anchoring reliability and resistance to dislodgement are insufficient
Solution Approach 1:
The patent divides the anchoring function into multiple independent helical anchors that can be deployed separately within the cardiac chamber, allowing each anchor to independently contribute to device stability while maintaining overall device simplicity and enabling reliable anchoring through distributed attachment points
Solution Approach 2:
The patent employs helical anchors with opposing handness (right-handed and left-handed threads) that create balanced anchoring forces, where the opposing configurations work together to prevent device rotation and dislodgement, enhancing reliability without significantly increasing complexity
3Stability of the object's composition
If helical anchors with opposing handness are used, then device stability and anti-rotation are improved, but device complexity increases
Solution Approach 1:
The patent combines multiple helical anchors with opposing handness into a single integrated implantable device structure, where the anchors are coordinated to work together as a unified system, achieving enhanced stability and anti-rotation properties while maintaining manageable device complexity through unified design and deployment
