Rotatable Caddy for Coiled Catheters and Sterile Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Endovascular procedures require efficient organization and management of multiple, varying-length medical devices like guidewires and catheters, which are often manually coiled and difficult to track and keep sterile, especially during complex procedures.
Innovation Solution
A rotatable holder with a hollow cylinder and multiple tracks, using malleable layers and bristles to secure coiled devices, allowing for independent rotation and stabilization in a saline solution, facilitating efficient storage and retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If guidewires and catheters are manually coiled and placed on the operating table or in water basins, then the devices can be stored during procedures, but tracking and organization become difficult and sterility is hard to maintain
Solution Approach 1:
The storage system divides the operating table surface into multiple discrete zones using individual trays or compartments. Each tray can hold specific coiled devices separately, preventing mixing and making tracking easier. The segmentation allows each device to be organized in its designated space while maintaining sterility through physical separation from non-sterile surfaces.
Solution Approach 2:
The patent introduces sterile barriers such as sterile drape sheets or sterile tray liners as intermediaries between the coiled devices and the operating table surface. This intermediary layer maintains sterility while still allowing the devices to be coiled and stored, solving the contradiction between ease of handling and sterility maintenance.
2Productivity
If multiple coiled devices are stored on the operating table, then they are accessible during procedures, but manual handling increases and tracking errors occur
Solution Approach 1:
The patent combines multiple individual device storage functions into a single integrated storage system or tray assembly. By merging several coiled devices into one organized unit on a unified platform, the system reduces the number of separate handling operations needed while maintaining accessibility of all devices during the procedure.
Solution Approach 2:
The devices are pre-coiled and pre-organized in their storage trays before the procedure begins. This preliminary organization reduces the need for manual coiling and rearrangement during the procedure, thereby improving productivity while minimizing additional manual handling operations.
3Device complexity
If devices are coiled manually without structured storage, then storage is simple, but organization and retrieval efficiency decrease
Solution Approach 1:
The storage system uses segmented trays or compartments that provide structured organization for coiled devices. Each segment or tray is designed to hold one or more specific devices, creating a simple yet effective structure that enhances retrieval efficiency without requiring complex mechanical systems.

AI summary
A device comprises a cylinder and a tank. The cylinder includes a first disc and a second disc, multiple struts arranged orthogonally between the first disc and the second disc, and a plurality of walls, parallel to the first disc and the second disc. The struts generally form a circumference with spaces between each of the struts along the circumference; the walls extend through the space between the struts and beyond the circumference of the struts; and the walls form a plurality of tracks around the circumference of the struts. An axle extends orthogonally between the first disc and the second disc, and at least a portion of the cylinder rotates about the axle. The tank includes a basin to hold a liquid solution. When a catheter is wound around the cylinder, the rotation of the cylinder causes the catheter to be coated in the liquid solution from the basin.
