Retro Access Vascular Sheath with Flexible Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vascular sheath technologies do not allow for safe redirection within a vessel after initial insertion, posing risks of access site loss, vessel wall damage, and bleeding, necessitating a second puncture and procedure if a different vascular target area becomes desirable.
Innovation Solution
Development of vascular sheaths with side access openings and flexible areas along their length, enabling the sheath to be bent and repositioned without removal, allowing access in either direction within a blood vessel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a second puncture is made in another vessel to access a different vascular target area, then access to the new target area is achieved, but the risk of complications increases and the procedure requires a second day
Solution Approach 1:
The vascular sheath is designed with multiple side access openings at different orientations and a flexible area enabling bending, allowing it to serve multiple functions: initial insertion in one direction, then redirection to access different vascular target areas without removal or second puncture
Solution Approach 2:
The sheath incorporates a flexible area that allows dynamic repositioning and bending after initial insertion, enabling the operator to redirect the distal end to access different vascular targets while maintaining the same access site
2Adaptability or versatility
If a second puncture is made in another vessel, then access to a different vascular target area is achieved, but the procedure time and complexity increase
Solution Approach 1:
The sheath's multiple side access openings and flexible area enable it to access multiple vascular target areas during a single procedure, eliminating the need for a second puncture and second-day procedure
Solution Approach 2:
The sheath is pre-configured with side access openings and flexible areas during manufacturing, allowing immediate redirection capability upon insertion without requiring additional procedures or time
3Adaptability or versatility
If the sheath is redirected by creating another puncture, then access to a different vascular target area is achieved, but the complexity of the procedure increases
Solution Approach 1:
The sheath integrates multiple access openings and flexible positioning capability into a single device, allowing one procedure to accomplish what would otherwise require multiple punctures and procedures
Solution Approach 2:
The invention combines the functions of multiple punctures and multiple access directions into a single sheath insertion, merging what would be separate procedural steps into one unified operation
