Open the CIPO recordAbstract From the Canadian patent
A variable curvature stent limb is disclosed. The stent limb has an S-shape enabling it to be compressed into a substantially flat condition. A stent formed from a plurality of these variable curvature stent limbs is highly , compressible, such that it is compatible with a low-profile delivery device. This stent may be useful over a wider range of body vessel diameters and may possess a greater fatigue life, since this stent may provide a more controlled constant radial force.
