Solution Overview

Problem

Current guidewire management systems are inefficient, leading to increased procedural time, space requirements, and contamination due to the cumbersome storage and exchange of guidewires, which results in higher costs and risks of foreign-body infections.

Innovation Solution

A spool-based apparatus with a housing and brake mechanism that allows for controlled retraction and storage of guidewires, preventing tangling and uncoiling, while reducing space requirements and minimizing contamination risks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If guidewires are stored in conventional bowls or basins, then storage capacity is provided, but wires become tangled and access becomes difficult

Engineering Contradiction:
Improvewire accessVSAvoidstorage structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The storage device is divided into multiple compartments, each capable of holding individual guidewires in an uncoiled state. This segmentation prevents wires from tangling while maintaining organized access to each wire separately.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention transitions from traditional horizontal bowl storage to a vertical tower structure with multiple levels. This dimensional change allows wires to be stored upright in individual compartments, preventing tangling and improving accessibility without increasing horizontal space requirements.

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

2Ease of operation

If guidewires are laid out uncoiled for procedures, then accessibility is improved, but space requirements increase significantly

Engineering Contradiction:
Improvewire accessibilityVSAvoidroom space
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The storage device utilizes vertical space through a tower structure with multiple levels, allowing guidewires to be stored in an uncoiled state without occupying excessive horizontal floor space. This vertical organization maintains wire accessibility while minimizing the footprint in the operating room.

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

3Area of stationary object

If guidewires are coiled for storage, then space is reduced, but potential energy causes uncoiling and contamination

Engineering Contradiction:
Improvestorage spaceVSAvoidcontamination risk
Core Design Contradiction:
Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The device stores guidewires in a vertical uncoiled configuration within individual compartments rather than coiling them horizontally. This vertical arrangement eliminates the potential energy storage associated with coiling, preventing spontaneous uncoiling and contamination while maintaining compact space utilization.

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

Solution Approach 2:

The device includes a sterile barrier that can be disposed of after use, maintaining sterility for each wire without requiring complex reusable sterilization systems. This approach addresses contamination prevention through a simple, cost-effective solution.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

4Adaptability or versatility

If multiple wire exchanges are performed, then complex procedures can be accommodated, but procedural time increases

Engineering Contradiction:
Improveprocedure capabilityVSAvoidexchange time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

Multiple guidewires are pre-prepared and organized in individual compartments before the procedure begins. This preliminary organization allows for rapid wire exchanges during the procedure, as each wire is readily accessible and requires minimal setup time, thereby reducing overall procedural time while maintaining the ability to perform complex multi-wire procedures.

Inventive Principle:
Principle #10Preliminary action

5Object-affected harmful factors

If guidewires are stored in saline baths, then cleanliness is maintained, but the storage device becomes large and cumbersome

Engineering Contradiction:
Improvecontamination preventionVSAvoidstorage device size
Core Design Contradiction:
Object-affected harmful factorsVSVolume of stationary object

Solution Approach 1:

The device incorporates a disposable sterile barrier that maintains wire cleanliness without requiring large volumes of saline solution. This approach prevents contamination while keeping the device compact, eliminating the need for bulky saline baths associated with traditional storage methods.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

AI summary

An apparatus for storing and directing a guidewire used to guide an instrument is provided and includes a spool. The spool receives the guidewire and a spool wire. Rotation of the spool in a first direction retracts the guidewire and the spool wire around the spool. The apparatus also includes a wire connector that operatively couples the spool wire and the guidewire together. The apparatus further includes a housing that houses the spool. The housing includes first and second apertures. The first aperture is sized to prevent the wire connector from passing through the first aperture but allow the guidewire and the spool wire to pass through the first aperture. The second aperture is sized to allow the wire connector and the guidewire and the spool wire to pass through the second aperture. The first and second apertures merge together such that the guidewire and the spool wire may move between the first and second apertures.
