Solution Overview

Problem

Current interventional catheter systems face challenges in providing safe and reliable material removal from internal body sites without causing complications, while also requiring improved operator convenience, mobility, and control during minimally invasive procedures.

Innovation Solution

The development of interventional catheter assemblies with a flexible catheter component and a control module that houses operational and control components, allowing for remote operation of the operating head via sealed passageways and various control features, including a detachable and portable control component for enhanced operator flexibility and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a console-type controller is used to house non-disposable components, then system reliability is improved, but operator mobility and accessibility are reduced

Engineering Contradiction:
Improvesystem reliabilityVSAvoidoperator mobility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system is divided into a stationary console-type controller housing non-disposable components (pumps, drive systems, control electronics) and a portable handheld control component that can be moved freely. This segmentation allows the heavy, complex components to remain fixed for reliability while the control interface is portable for operator mobility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A wireless communication system acts as an intermediary between the stationary console controller and the portable handheld control component. This allows the operator to control the catheter system from a mobile position while the main system remains stationary, resolving the contradiction between reliability and mobility.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If control features are positioned at a proximal region of the catheter, then system integration is improved, but operator access during intervention is reduced

Engineering Contradiction:
Improvesystem integrationVSAvoidoperator access
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The control system is segmented into a proximal control housing integrated with the catheter system and a separate handheld control component. The proximal housing contains the integrated control features while the handheld component provides accessible controls to the operator, resolving the contradiction between integration and accessibility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The control interface is extended from the proximal region of the catheter to a handheld device that the operator can hold and manipulate in three-dimensional space. This dimensional extension allows control features to be both integrated in the proximal region and accessible to the operator during the procedure.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Device complexity

If a single operational component interfaces with the catheter, then device simplicity is improved, but control functionality and versatility are reduced

Engineering Contradiction:
Improvedevice simplicityVSAvoidcontrol functionality
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The handheld control component serves multiple functions: it controls the catheter operation, provides wireless communication with the console, displays system status, and allows operator navigation. This multi-functional design provides versatile control functionality while maintaining relative device simplicity through a single primary interface.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

Interventional catheter assemblies and components providing improved operational control of interventional catheters and/or operating heads of interventional catheters are provided. In general, controllers incorporate at least two operator selectable control features for controlling operation of the interventional catheter and/or an operating head, and are housed independently of the interventional catheter operating systems and other control systems, which may be provided in a housing located or locatable at a proximal region of the interventional catheter. The controller may be both dockable in and removable from the housing, and is operable in both a docked condition and a removed condition, providing flexibility and mobility in operational control during an interventional procedure.
