Catheter Retainer Channel Preserves Pre-Shaped Angle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pre-shaped catheters experience creep deformation over time, leading to a reduction in the pre-shaped angle of their tips, which can render them unsuitable for vascular access procedures, necessitating additional steam shaping and potentially causing operational inefficiencies and damage.
Innovation Solution
A catheter retainer with a channel configuration that includes a first channel section for straight sections and a second channel section for bent sections of the catheter tip, maintaining the pre-shaped angle and preventing creep deformation, allowing for direct use without additional shaping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If pre-shaped catheters are provided with angled tips to enable direct use, then operational efficiency is improved, but the pre-shaped angle deteriorates over time due to creep deformation
Solution Approach 1:
The catheter tip is pre-shaped at the factory to the required angle before delivery. The retainer device is designed to maintain this pre-shaped angle by providing a channel that guides and preserves the angled configuration, preventing creep deformation during storage and use without requiring additional shaping operations.
Solution Approach 2:
The retainer device acts as an intermediary between the catheter and the operator. It includes a channel with specific geometric features that interact with the catheter tip to maintain the pre-shaped angle, serving as a protective intermediary that prevents direct exposure to conditions that would cause deformation.
2Ease of operation
If catheters are steam-shaped at the tip to facilitate passage through tortuous blood vessels, then ease of operation is improved, but additional preparation time is required
Solution Approach 1:
The catheter tip is pre-shaped at the factory to the required angle before delivery. The retainer device is designed to maintain this pre-shaped angle by providing a channel that guides and preserves the angled configuration, preventing creep deformation during storage and use without requiring additional shaping operations.
3Ease of operation
If catheter tips are bent at predetermined angles for direct insertion, then ease of operation is improved, but the catheter may get jammed in certain vascular segments
Solution Approach 1:
The retainer device allows the catheter tip to maintain a fixed pre-shaped angle while enabling dynamic adjustment during the procedure. The channel geometry supports the predetermined angle for direct insertion, but the overall system allows operators to adapt to different vascular anatomies as needed.

AI summary
A catheter retainer and a catheter-protecting device including the catheter retainer are disclosed. The catheter retainer defines a channel configured for passage of a pre-shaped section of a catheter therethrough. The channel includes a first channel section and a second channel section. The first channel section is configured for passage of a straight section of a tip of the catheter therethrough, and the second channel section is configured for passage of a bent section of the tip of the catheter therethrough. The catheter retainer including the first channel section and the second channel section is able to ensure that an angle of a pre-shaped end of the catheter can be maintained without decreasing for a long time, allowing an operator to directly use and deploy the catheter at a lesion site without having to subjecting it to a steam shaping process. This can reduce the time required for preoperative preparation.
