Customizable Flow Diverter Length Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flow diverter systems for treating cerebral aneurysms require a wide range of sizes and lengths, leading to a large number of stock-keeping units (SKUs) that are economically burdensome and complicate surgical procedures.
Innovation Solution
A customizable flow diverter system that includes an elongate tubular member with a deployment wire and a cuttable flow diverter, allowing for variable length adjustments by cutting the flow diverter within a tubing section marked with graduation markings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wide range of flow diverter sizes and lengths are provided to treat various cerebral aneurysms, then the adaptability to different patient anatomies is improved, but the number of SKUs increases leading to economic burden and operational complexity
Solution Approach 1:
The flow diverter is designed with a standardized delivery system configuration that can accommodate multiple lengths of flow diverter implants. The delivery catheter and deployment mechanism serve universal functions across different flow diverter lengths, allowing a single SKU of delivery system to handle multiple aneurysm treatment scenarios without requiring separate delivery systems for each flow diverter size.
Solution Approach 2:
The flow diverter implant is provided in segmented length options (e.g., 10mm, 15mm, 20mm, 25mm, 30mm) that can be selected based on the specific aneurysm size and location. This segmentation allows the system to cover a wide range of aneurysm dimensions while maintaining a manageable number of SKUs, as the delivery system remains standardized across all length variants.
2Manufacturing precision
If multiple flow diverter lengths are stocked to match various aneurysm locations, then the precision of matching flow diverter to aneurysm is improved, but the inventory management complexity and cost increase
Solution Approach 1:
The system provides flow diverters with specific length parameters (10mm, 15mm, 20mm, 25mm, 30mm) that can be precisely selected to match the measured dimensions of the target aneurysm. This parameter-based approach allows for precise matching while keeping the SKU count manageable through standardization of the delivery system across all length variants.
3Ease of manufacture
If fixed length flow diverters are used, then the manufacturing and packaging process is simplified, but the flexibility to optimize treatment for each patient is reduced
Solution Approach 1:
The system transitions from a static, fixed-length flow diverter approach to a dynamic selection process where the optimal length (10mm, 15mm, 20mm, 25mm, or 30mm) is selected based on real-time assessment of the patient's aneurysm characteristics. This dynamic approach maintains manufacturing simplicity through standardized production of discrete length variants while maximizing treatment flexibility through clinical decision-making.

AI summary
Neurovascular flow diverter and delivery systems, and methods of using the same are described herein. The systems can include a customizing member including an introducer sheath, a catheter, a deployable flow diverter that can be contained in the introducer sheath or in the catheter, a core wire, and one or several deployment features coupled to the core wire and engaging the flow diverter. The customizing member includes a tubing extending along and around a distal portion of the introducer sheath. This tubing is cuttable and contains a distal end of the flow diverter. The length of the flow diverter can be customized by cutting through the tubing and the therein contained flow diverter.
