LowElast
Improved Retention Forces for Crimped L605 Stents and Reduced Recoil 
LowElast is a heat treatment
- that reduces the “spring back“ during crimping of L605 stents
- that reduces the recoil of the expanded / dilated stents
- for a safe L605 stent-balloon system
Common L605 Stents
L605 stents show severe problems during crimping due to the
- “spring-back” effect: high elastic strain causes a partial reopening of the stent after crimping
- non-constant mechanical properties: straightening of the annealed tubing causes unstable mechanical properties
Advantages of LowElast
- Reduced yield strength thus minimized spring-back effect
- High retention forces of the stent on the balloon catheter
- Adjustable and stable mechanical properties of the L605 stents
- Reduced recoil
