Interactive Coiling Parameter Determination for Aneurysm Filling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for determining coiling parameters for filling lumens, such as aneurysms, with coils lack efficiency and flexibility, particularly for small aneurysms where packing percentage does not significantly impact recurrence rates, and do not allow for interactive selection of coil types and parameters during deployment.
Innovation Solution
A method and device that utilize three-dimensional rotational angiography to determine the volume of the lumen and interactively calculate coiling parameters like the number of coils, coil thickness, or coil length, allowing for selection of different coil types based on desired packing and lumen shape, with a user-friendly interface for practitioners.

Engineering Contradiction Analysis
1Productivity
If current methods for determining coiling parameters are used, then the procedure is simple, but the efficiency and flexibility are insufficient
Solution Approach 1:
The patent replaces manual calculation and estimation methods with an automated computer-based system that performs interactive determination of coiling parameters. The system uses software to calculate optimal coil numbers, sizes, and configurations based on lumen geometry, substituting the mechanical/manual process with an automated computational approach that improves efficiency while maintaining clinical decision-making capability
Solution Approach 2:
The patent introduces a computer-based interactive determination system as an intermediary between the practitioner and the coiling procedure. This intermediary tool processes complex calculations and provides recommendations without replacing the practitioner's decision-making, thereby improving efficiency while keeping the overall system complexity manageable through user-friendly interfaces
2Adaptability or versatility
If fixed coiling parameters are used, then the procedure is straightforward, but the flexibility for selecting coil types and parameters is limited
Solution Approach 1:
The patent implements a dynamic interactive determination system that allows practitioners to adjust parameters and explore different coil configurations in real-time. The system responds to user inputs by recalculating optimal parameters, enabling flexible adaptation to different lumen geometries and clinical scenarios while maintaining an organized workflow through its structured interface
Solution Approach 2:
The patent segments the coil filling procedure into distinct parameter categories (coil number, coil size, coil configuration) that can be independently adjusted and optimized. This segmentation allows practitioners to flexibly select and modify specific parameters without overwhelming complexity, as each parameter can be determined and adjusted separately through the interactive system
