Open the CIPO recordAbstract From the Canadian patent
A medical implant such as a self-expanding shape memory alloy stent with a strut matrix formed by cut patterns in a wall of a tubular workpiece (12) can be enhanced by arranging for the line of the laser beam when cutting the struts (62) to be one that does not pass through the longitudinal rotational axis (10) of the tubular workpiece. Such "off-axis-" cutting can modify the cross-sectional shape and area of each strut along its length. Such , modulation can enhance the fatigue resistance of the stent matrix or increase , the radial force that the stent matrix is capable of exerting on bodily tissue within which it is implanted.
