Sensor-Guided Anastomosis Devices for Fibrotic Tissue Compression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Magnetic force-based anastomosis devices struggle to accommodate challenging anatomies, particularly when fibrotic tissue is interposed between device components, leading to uneven magnetic attraction and difficulty in compressing the fibrotic tissue effectively.
Innovation Solution
Anastomosis devices equipped with sensors, such as gyroscopes and accelerometers, provide precise characterization of device component alignment and orientation, allowing actuators to adjust positions and orientations to enhance magnetic force distribution, and include structures that can be inflated or transitioned to therapeutic configurations to compress fibrotic tissue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If magnetic force-based device components are used for anastomosis creation, then the devices can be simplified and easier to operate, but the ability to accommodate challenging anatomies with fibrotic tissue is poor
Solution Approach 1:
The patent incorporates sensors (such as force sensors, magnetic sensors, or imaging systems) that provide real-time feedback on the magnetic attraction forces between device components and the intervening tissue. This feedback allows the system to detect when fibrotic tissue is present and adjust the magnetic force application accordingly, resolving the contradiction between ease of operation and adaptability to challenging anatomies.
Solution Approach 2:
The magnetic force application is made dynamic and adjustable rather than fixed. The system can vary the strength and distribution of magnetic forces in real-time based on tissue characteristics, allowing it to adapt to fibrotic tissue while maintaining ease of operation through automated adjustment.
2Force
If magnetic components are positioned to maximize attraction, then the magnetic force is strong, but the fibrotic tissue cannot be compressed effectively due to unbalanced forces
Solution Approach 1:
The system transitions from uniform magnetic force application to localized force application. By using multiple magnetic elements or adjustable magnetic components, the system can concentrate magnetic force specifically at regions where fibrotic tissue is detected, while maintaining appropriate forces elsewhere. This local quality adjustment enables effective fibrotic tissue compression without compromising overall magnetic attraction.
Solution Approach 2:
The system dynamically changes the parameters of magnetic force application (strength, distribution, and direction) based on real-time feedback about tissue composition. When fibrotic tissue is detected, the system adjusts magnetic parameters to increase compression force at the appropriate location, resolving the contradiction between strong magnetic attraction and effective tissue compression.
3Measurement precision
If precise characterization of device component position and orientation is achieved, then the magnetic force distribution can be optimized, but the device complexity increases
Solution Approach 1:
The system uses self-service measurement approaches where the device components themselves carry sensors that automatically characterize their own position and orientation relative to each other and the tissue. This eliminates the need for complex external measurement systems, achieving precise characterization while minimizing added device complexity through integrated sensing.
