WebSpring rate is measured in pounds per inch. That is pounds of force per inch of travel. This means that the load will depend on the amount of inches you travel and the distance traveled will depend on the load being placed. It is all proportional and accumulative when it comes to spring rate. WebNitinol allows the design of self-expanding stents with biased stiffness, meaning that the stents exert only low outward force, but resist deformation with a much higher force.
