Distal Impingement Structure for Mixing Multi-Part Agents
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current devices and methods for delivering multi-part agents to target tissue sites within the gastrointestinal tract during or after surgical procedures are limited, often resulting in ineffective application and clogging issues due to premature curing of agents within catheters.
Innovation Solution
A medical device with multiple lumens and a distal impingement structure that mixes and applies two or more fluid agent components at a treatment site, preventing premature curing and ensuring effective adherence to the tissue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-part agents are delivered through catheters, then the agent can be transported to the treatment site, but premature curing occurs within the catheter causing clogging
Solution Approach 1:
The agent is divided into multiple separate parts or components that are delivered through separate lumens or containers. Each part remains stable during transport but combines only at the treatment site, preventing premature curing and clogging in the catheter system.
Solution Approach 2:
An intermediary mechanism is used to prevent premature curing, such as keeping agent components separated by physical barriers ( membranes, separate lumens) or using stabilizing agents that prevent reaction until delivery to the treatment site.
2Reliability
If agents are delivered to target tissue sites, then tissue protection can be achieved, but ineffective application occurs due to clogging
Solution Approach 1:
By segmenting the agent into multiple deliverable components that combine only at the treatment site, the system ensures effective application without clogging, as each component can pass through the catheter system independently.
Solution Approach 2:
The agent components are prepared and positioned for delivery in advance, but the actual combination and application occur only when needed at the treatment site, ensuring effectiveness without premature reactions.
3Reliability
If multiple agent components are used, then better tissue protection is achieved, but device complexity increases
Solution Approach 1:
The complex multi-component agent system is segmented into separate deliverable units that can be independently managed during transport but combine automatically at the treatment site, reducing the complexity of managing multiple components through the catheter system.
Solution Approach 2:
Multiple agent components are designed to merge or combine automatically at the treatment site through mixing mechanisms, eliminating the need for separate delivery and management of each component, thereby reducing overall system complexity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device efficiently delivers and mixes multi-part agents at the target site, reducing procedure time and minimizing harm by avoiding clogging and premature curing, thereby effectively protecting tissue from further degradation.
Implementation Method 1

AI summary
An agent delivery device (10) comprises: - one or more agent containers (24) at a proximal end (12) of the agent delivery device, wherein the one or more agent containers are configured to contain one or more fluids (17A, 17B); - an insertion section (20) comprising a tube (23) defining one or more lumens (14), the insertion section coupled to the agent containers such that the one or more fluids may flow from the agent containers to the one or more lumens and out of one or more outlets (32) of the one or more lumens; and - a distal impingement structure (34) at the distal end (30) of the insertion section, the distal impingement structure comprising an impingement surface (51) arranged relative to one or more outlets to impinge the one or more fluids dispensed from the one or more outlets to cause mixing of the one or more fluids for application of the fluids at a treatment site (40).
