Catheter Side Branch Orientation via Balloon Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current stent technologies face challenges in effectively treating vessel bifurcations due to difficulties in accurately positioning and orienting stents within the complex anatomy of bifurcated vessels, leading to suboptimal deployment and expansion.
Innovation Solution
The catheter assembly includes a side catheter branch connected to the main and/or side balloons, ensuring consistent orientation prior to and after deployment, using methods such as adhesives, coextrusion, or welding to maintain alignment during inflation and deflation, allowing precise placement and expansion of stents at vessel bifurcations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional stent technologies are used for treating vessel bifurcations, then general stent deployment is possible, but accurate positioning and orientation of stents at bifurcations is difficult
Solution Approach 1:
The catheter assembly is divided into separate functional components: a main catheter body with inflation balloon and a side catheter branch. This segmentation allows independent positioning and orientation control of each branch, enabling precise stent placement at bifurcation locations without requiring the entire assembly to be complex.
Solution Approach 2:
The side catheter branch acts as an intermediary element that bridges the main catheter body and the target bifurcation vessel. By connecting to the main catheter through a controlled interface, it provides a straightforward mechanism for achieving accurate positioning and orientation at the bifurcation site.
2Stability of the object's composition
If the side catheter branch is not connected to the balloons, then the catheter assembly structure is simpler, but the orientation of the side catheter branch relative to the balloons is inconsistent
Solution Approach 1:
The side catheter branch is merged with the main catheter body through a connection structure that integrates the orientation of both components. This merging ensures that the relative orientation between the side branch and the balloons remains consistent throughout the inflation and deflation cycles, providing stable positioning without requiring complex independent control mechanisms.
3Manufacturing precision
If the side catheter branch is positioned within the folds of the balloons during assembly, then the orientation is maintained, but the assembly process becomes more complex
Solution Approach 1:
The side catheter branch is pre-positioned within the folds of the balloons during the manufacturing process. This preliminary action ensures that the correct orientation is established before the product reaches the user, eliminating the need for complex real-time adjustment mechanisms during the procedure and simplifying the overall manufacturing process.

AI summary
A side catheter branch of a catheter assembly is oriented with respect to the main or side balloons of a catheter assembly. In some examples, the orientation is accomplished by connecting the side catheter branch to the main and/or side balloons or waist portions thereof. In other examples, the side catheter branch is positioned within the folds of the main or side balloons during assembly of the catheter assembly. In this manner, the side catheter branch remains in a known orientation with respect to the main and/or side balloons prior to and/or after deployment.
