Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Embolic delivery systems face issues with connection integrity deterioration due to fluid contamination, leading to improper detachment of embolic agents in vascular treatments.
Innovation Solution
An integral wiping system within the grip assembly of embolic delivery devices, featuring annular wipers that create an interference fit to prevent fluid and debris from reaching electrical contacts, ensuring clean connections and reliable detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical contacts are exposed for connection, then electrical connection is established, but fluid contamination deteriorates connection integrity
Solution Approach 1:
A wiper element is introduced as an intermediary component between the electrical contacts and the external environment. The wiper engages with the outer surface of the medical device during insertion, wiping away fluids and contaminants before they can reach the electrical contacts, thus protecting connection integrity while allowing electrical connection to be established
Solution Approach 2:
The wiper performs a preliminary cleaning action on the outer surface of the medical device during the insertion process. By wiping the surface before the electrical contacts make contact, the system prevents contamination from occurring in the first place, ensuring reliable electrical connection
2Reliability
If wipers are added to protect electrical contacts, then fluid contamination is reduced, but device complexity increases
Solution Approach 1:
The wiper element is integrated into the housing structure of the grip assembly, merging the protective wiping function with the existing structural components. This consolidation adds the necessary protection without proportionally increasing overall device complexity, as the wiper utilizes the existing housing space and insertion mechanism
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
The wiping system effectively maintains connection integrity by preventing fluid contamination, ensuring accurate and reliable detachment of embolic agents during vascular treatments.
Implementation Method 1
having a diameter smaller than a diameter of the proximal end of the medical delivery system, thereby creating an interference fit between the wiper and the medical delivery system

AI summary
A grip assembly for an embolic delivery device is described, where said grip assembly includes an integral wiping system utilizing one or more wipers. The grip assembly is constructed and arranged to allow an embolic delivery device to be inserted into the grip quickly and easily, without shifting undue attention away from the patient to the device. The wiper or wipers prevent any fluids or debris that may be present on a proximal end of the embolic delivery device from entering the interior of the grip assembly, thereby preserving a clean environment for making solid electrical connections between contacts in the grip assembly and corresponding contacts on the embolic delivery device.
