Abstract

Normally, when stents are bent, inside the body of the stented patient, there is head-to-head collision between facing V-points on the inside of the bend. However, by alternating between two whole numbers the number of struts between successive connectors around the circumference of each of the stenting rings, the V-points are caused to veer circumferentially in opposite directions as they approach each other on the inside of the bend, so allowing them to pass by each other without collision, thereby allowing in the same stent both close packing of the ring stack, and an enhanced ability to tolerate severe bending, after placement in the body.
