1. A method of forming a channel in a selected portion of the outer wall of a stent, comprising:

  • aligning a diode pumped Q-switched Nd/YAG laser assembly with a tubular member;

    generating a laser beam having a wavelength in the ultraviolet range;

    impinging the laser bean on a selected portion of the outer surface of the tubular member;

    moving the tubular member relative to the laser beam to machine a channel into the outer surface of the tubular member;

    moving the tubular member relative to the laser beam to cut a stent pattern incorporating the channel into the outer surface of the tubular member so as to form a stent.
