Helical Bypass Conduit for Collateral Vessel Implantation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cardiovascular procedures for treating occluded vessels are either highly invasive with significant morbidity and mortality risks or minimally invasive but limited in effectively restoring blood flow, requiring shorter hospital stays and quicker recovery times.
Innovation Solution
A percutaneous bypass method using a helical wire body with connectors to create a bypass conduit that is implanted into a collateral vessel, maintaining patency and sufficient blood flow to substitute for the occluded vessel, thereby reducing the effects of cardiovascular diseases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If open surgical procedures are used to treat occluded vessels, then direct access to the target region is achieved, but the procedure becomes highly invasive with significant morbidity and mortality risks
Solution Approach 1:
The patent introduces a bypass conduit as an intermediary structure that connects a collateral vessel to the occluded vessel, allowing blood flow to be redirected through a alternative pathway. This mediator approach enables treatment of the occluded vessel without requiring direct open surgical access to the target region, thereby reducing the harmful effects of invasive surgery while maintaining therapeutic effectiveness
2Loss of time
If minimally invasive endovascular procedures are used, then hospital stay and recovery times are reduced, but the ability to effectively restore blood flow is limited
Solution Approach 1:
The bypass conduit is constructed from multiple segments including a helical wire body with multiple turns and separate connectors. This segmentation allows the conduit to be delivered through minimally invasive endovascular techniques while maintaining structural integrity and effective blood flow restoration. The modular design enables the conduit to expand and conform to the vessel anatomy, ensuring reliable blood flow restoration without requiring open surgery
Solution Approach 2:
The bypass conduit utilizes composite construction combining a helical wire body with connectors, integrating different material properties to achieve both minimally invasive deliverability and effective blood flow restoration. The composite structure provides the necessary strength, flexibility, and expandability to restore blood flow reliably while being deliverable through small incisions
3Reliability
If a bypass conduit is implanted into a collateral vessel, then blood flow is restored effectively, but the procedure complexity increases
Solution Approach 1:
The bypass conduit is divided into segmented components including a helical wire body with multiple turns and separate connectors that can be assembled during the procedure. This segmentation allows the complex conduit to be delivered through minimally invasive techniques while maintaining the structural complexity necessary for effective blood flow restoration. The modular design enables step-by-step assembly within the vessel, managing procedural complexity
