ECM Shield Anchoring for Vascular Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vascular treatment methods face limitations and risks such as obstruction, vessel damage, thrombosis, and complications like emboli and hemorrhage, which are not adequately addressed in treating vascular diseases and disorders.
Innovation Solution
A device comprising an ECM material section and an anchoring member is introduced into a blood vessel, shielding a portion of the vessel and allowing for additional treatment, with the anchoring member maintaining the ECM material in a fixed position to prevent obstruction and facilitate treatment while allowing blood flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a device is introduced to treat a blood vessel, then treatment effectiveness is improved, but risk of vessel obstruction and damage increases
Solution Approach 1:
The patent introduces a protective sheath or delivery catheter as an intermediary device that shields the blood vessel from direct contact with treatment devices and embolic materials. This intermediary structure allows treatment to be delivered while preventing harmful interactions between the treatment apparatus and the vessel wall, thus improving treatment effectiveness while reducing vessel damage risk
Solution Approach 2:
The patent employs flexible protective coatings or thin film barriers on treatment devices that prevent direct contact between the device and blood vessel wall. These flexible shells allow the device to navigate and treat the vessel while minimizing mechanical damage and obstruction risks, enabling effective treatment with reduced harmful effects
2Reliability
If embolic protection devices are used during vascular treatment, then safety is improved, but device complexity increases
Solution Approach 1:
The patent combines embolic protection functionality with the primary treatment device into a single integrated apparatus. By merging the protection function with the treatment function, the patent achieves improved safety without proportionally increasing device complexity, as the protective and therapeutic functions work together within a unified device architecture
Solution Approach 2:
The patent designs treatment devices with multiple functions, including both treatment delivery and embolic protection capabilities. This multi-functionality allows a single device to perform both therapeutic and protective roles, improving safety while avoiding the need for separate dedicated protection devices that would increase overall system complexity
