Multi-lumen Embolization Coil Delivery System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing embolization coil delivery systems require reloading and manual deployment of multiple coils, which is inefficient and time-consuming, especially for procedures involving large aneurysms or complex artificial embolism techniques.
Innovation Solution
A multi-embolization coil delivery system preloaded with multiple coils, featuring independently manipulable deployment members and lumens, allowing for simultaneous or sequential deployment of embolization coils without the need for reloading, with options for different coil configurations and materials to enhance occlusion and support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple embolization coils are delivered using existing systems requiring reloading, then the ability to deliver multiple coils is achieved, but procedural time and operational efficiency deteriorate
Solution Approach 1:
The delivery system is preloaded with multiple embolization coils in separate lumens before the procedure begins. The operator can select and deploy coils in sequence without reloading, as the coils are already positioned within the catheter assembly, eliminating time-consuming reloading steps during the procedure.
Solution Approach 2:
Multiple embolization coils are nested within separate lumens of the same catheter assembly. Each coil is contained within its own lumen, allowing multiple coils to be delivered through a single catheter without requiring multiple catheters or reloading operations.
2Quantity of substance
If multiple embolization coils are delivered using existing systems requiring manual reloading, then multiple coils can be deployed, but device complexity and operational steps increase
Solution Approach 1:
Multiple embolization coils that would traditionally require separate delivery systems are merged into a single multi-lumen catheter assembly. The multiple lumens are integrated within one catheter body, allowing all coils to be delivered through a single device rather than requiring multiple separate systems.
Solution Approach 2:
The multi-lumen catheter assembly serves multiple functions: it can deliver different types of embolization coils (scaffold, packing, hybrid) through its multiple lumens, and the operator can selectively deploy coils in various sequences. This universal design replaces the need for multiple specialized single-coil delivery systems.
3Quantity of substance
If embolization coils are delivered sequentially through reloading, then multiple coils reach the target, but procedural efficiency and workflow smoothness deteriorate
Solution Approach 1:
The multi-lumen catheter assembly enables continuous deployment of embolization coils without interruption. The operator can sequentially manipulate deployment members to release coils one after another in a continuous workflow, eliminating the stop-and-go nature of reloading operations and maintaining continuous useful action throughout the procedure.
