THE CHALLENGE
When navigating complex anatomy, stability and flexibility need to work together.
In one complex vascular intervention application, a customer experienced significant shape instability within critical bending segments of the access pathway.
01
THE PROBLEM
The original sheath design demonstrated shape instability at critical bending pathway segments, affecting pathway establishment efficiency and increasing potential procedural challenges.
02
THE ENGINEERING REQUIREMENT
The design needed to maintain shape stability while navigating demanding bends and support the performance characteristics required for vascular intervention.
THE SALT MEDICAL APPROACH
Targeted structural optimisation
Following a systematic review of the application requirements, the Salt Medical team optimised the sheath structure using coiled spring reinforcement principles.
Anti-kinking performance
Maintaining shape stability when passing through curves.
Pushability
Supporting smooth advancement with minimal resistance.
Torque transmission
Supporting rapid response of the distal end during torquing with a one to one response.
THE RESULT
Maintaining performance through demanding bends
No kinking observed in the improved sample
Anti-Kinking
Improved structural stability
Pushability
Smooth advancement
Torque transmission
One to one response and precise control
Application-focused
Optimisation based on the specific customer application scenario.
