Modular Guide-Wire Kit With Switchable Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The precise positioning and manipulation of guide-wires in minimally invasive medical procedures, particularly in angiology, are complex due to the sterically constrained space and the need for careful movement to avoid patient risk, with existing systems making it difficult to easily access and reconnect guide-wire positioning structures.
Innovation Solution
A guide-wire kit and assembly that includes a tapered introduction element with a haemostatic partition to prevent reverse bleeding, a torque body with switchable blocking means for controlled movement, and a slide control for manual orientation and translation of the guide-wire, allowing for easy disengagement and reconnection without axial removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the guide-wire positioning structures are firmly fixed to ensure stable manipulation, then the reliability of guide-wire positioning is improved, but the ease of accessing and reconnecting the structures deteriorates
Solution Approach 1:
The positioning system is divided into separate modular components: a guide-wire, a positioning element with blocking means, and a torque body. This segmentation allows each component to be independently accessed and manipulated while maintaining stable positioning when assembled, resolving the contradiction between stability and accessibility.
Solution Approach 2:
The positioning element is inserted into and nested within the guide-wire, with the blocking means engaging inside the guide-wire's internal lumen. This nesting arrangement provides stable positioning while allowing the components to be accessed through the proximal end without requiring axial removal of the guide-wire itself.
2Object-affected harmful factors
If the access point is sterically blocked to prevent contamination, then the patient safety is improved, but the ease of manipulating guide-wire structures deteriorates
Solution Approach 1:
The positioning element acts as an intermediary structure that engages with the guide-wire through the proximal end of the guide-wire kit. This intermediary allows manipulation of the guide-wire's distal tip while maintaining a sterile barrier at the access point, as the positioning element can be adjusted without compromising the sterile field.
3Manufacturing precision
If the guide-wire is constrained within a fixed structure to ensure precise positioning, then the manufacturing precision of positioning is improved, but the adaptability to different manipulation needs deteriorates
Solution Approach 1:
The blocking means is designed to be switchable between engaged and disengaged states, allowing the system to transition between a fixed, precise positioning state and a flexible, adaptable manipulation state. This dynamic capability enables the same structure to provide both manufacturing precision and manipulation flexibility as needed.

AI summary
Described herein is an assembly having a guide-wire having distally a flexible tip, and a guide-wire kit having comprising an introduction element of the guide-wire, a torque body, proximal to the introduction element, which includes blocking element of the guide-wire to the body, and a slide control which defines a support surface for the guide-wire, manually accessible to control (roto-)translations of the guide-wire, thereby orientations and/or sliding of the flexible tip, when the blocking element is in a release configuration. The torque body, the introduction element and the slide control are each disengageable, independently of the others, from the guide-wire in a radial direction.
