Solution Overview

Problem

Current medical procedures face challenges in effectively mixing treatment fluids with body fluids within body lumens, leading to incomplete uptake of treatment agents by targeted tissues and potential toxicity or overuse due to difficulties in accessing certain body parts and controlling fluid flow.

Innovation Solution

The turbulator device, featuring an elongate flow perturbing component with a nonporous proximal segment and a porous distal segment, includes a shape controlling component that adjusts from a low profile configuration for lumen access to an expanded profile configuration to induce turbulence, promoting mixing of treatment fluids with body fluids within the body lumen.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If treatment fluid is supplied into a body lumen for intraluminal treatment, then the treatment agent can reach the target tissue, but incomplete mixing with body fluid leads to incomplete uptake by targeted tissues and potential toxicity to downstream tissues

Engineering Contradiction:
Improvetreatment agent uptakeVSAvoidtoxicity to downstream tissues
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent employs a turbulator device that introduces mechanical disturbance and turbulence into the fluid flow within the body lumen. This mechanical vibration/turbulence enhances mixing between the treatment fluid and body fluid, ensuring complete uptake of the treatment agent by target tissues while preventing extraneous administration to downstream tissues, thereby reducing toxicity.

Inventive Principle:
Principle #18Mechanical vibration

2Quantity of substance

If mechanical agitators are used to physically displace and mix treatment fluids, then mixing effectiveness improves, but device complexity and difficulty of operation increase

Engineering Contradiction:
Improvemixing effectivenessVSAvoiddevice structure
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical agitator systems with a simpler turbulator device that relies on fluid dynamics and turbulence generation. This substitution maintains effective mixing while significantly reducing device complexity and ease of operation compared to mechanical displacement systems.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Quantity of substance

If high doses of treatment agents are administered to ensure complete uptake, then treatment effectiveness improves, but toxicity to healthy tissue increases

Engineering Contradiction:
Improvetreatment agent dosageVSAvoidtoxicity to healthy tissue
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The turbulator device creates controlled turbulence that enhances mass transfer and uptake efficiency of the treatment agent by target tissues. This improved uptake efficiency allows for reduced dosages of treatment agents while maintaining therapeutic effectiveness, thereby minimizing toxicity to healthy downstream tissues.

Inventive Principle:
Principle #23Feedback

AI summary

A turbulator (14) for promoting mixing of fluids passing through a body lumen includes an elongate flow perturbing component (16) and an elongate shape controlling component (50) freely slidable within the flow perturbing component. The turbulator is adjustable from a low profile, lumen access configuration to a deployed configuration via sliding the shape controlling component within the flow perturbing component. Adjusting the turbulator within a body lumen of a patient induces turbulence within a flow of fluid passing through the body lumen to increase mixing of a treatment fluid with the body fluid by way of the induced turbulence.
