Stent having a bridge structure

摘要

In a stent intended for implantation in a living body and having a bridge structure in which at least two bridges are coupled to one another at at least one node region on at least one of the bridges near the node region, the section modulus of the bridge varies along the length thereof, and the stresses arising at the node region upon deformation of the stent are distributed in the longitudinal direction of the bridge.
