Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Angiographic wires are difficult to handle and maneuver, prone to contamination, and require manual handling that increases the risk of entanglement and infection during procedures.
Innovation Solution
A guide device with a housing, base, and plunger system that allows for the delivery of fluid solvent to clean and lubricate angiographic wires, featuring adjustable locking mechanisms and ports for solvent delivery, ensuring easy manipulation and sterilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual handling of angiographic wires is used during procedures, then the wire can be manipulated and positioned, but the risk of contamination and entanglement increases
Solution Approach 1:
A guide device acts as an intermediary between the user and the angiographic wire. The device includes a guide member with a lumen through which the wire passes, allowing the user to manipulate the wire through the guide device rather than handling it directly. This intermediary structure reduces the risk of contamination while maintaining ease of manipulation.
2Productivity
If the wire is left unattended during procedures, then the user can attend to the patient with both hands, but the wire becomes prone to contamination and entanglement
Solution Approach 1:
The guide device is designed to securely hold and guide the angiographic wire in place, allowing the wire to effectively guide itself through the procedure. The guide member's lumen constrains the wire's movement, preventing entanglement and contamination while the user attends to other procedural tasks.
3Ease of manufacture
If traditional cleaning methods are used for angiographic wires, then cleaning can be performed, but the process is time-consuming and increases contamination risk
Solution Approach 1:
The guide device serves as a protective intermediary that prevents contamination in the first place by providing a controlled pathway for the wire. This preventive approach eliminates the need for time-consuming cleaning procedures, as the wire remains protected within the guide member's lumen throughout the procedure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates efficient cleaning and lubrication of angiographic wires, reducing contamination risk and enhancing procedural safety by allowing one-handed operation and secure handling.
Implementation Method 1
The base pad is a padded member having absorbent properties capable of retaining fluid solvents
Implementation Method 2
The plunger has a piston attached to a compression pad, which has the same absorbent properties as that of the base pad
Implementation Method 3
The fluid received via the port flows through the channel to the cradle, where the fluid impregnates the base pads. The fluid in the base pad is then emitted from the base pad as the angiographic wire exerts pressure on the base pad, thereby coating the angiographic wire in the fluid solvent and cleaning and lubricating the angiographic wires

AI summary
A method of guiding an angiographic wire while delivering fluid solvent to the wire. The method incorporates a guide device comprising a housing that is mated to a base in a manner that defines an aperture for slidably receiving the angiographic wire. A plunger is disposed within the housing in a adjustable manner via slots disposed on a flexible plunger arm and mating tabs disposed inside the housing. The plunger has an open position, a closed position, and one or more intermediate positions relative to the housing. The angiographic wire seats in the aperture, and the housing is mated to the base such that the wire is slidably retained in the aperture. The plunger is depressed such that a compression pad on the plunger is placed in contact with the wire, the wire being slidably retained between the compression pad and a base pad attached to the base.
