Abstract
Calculi, stones, calcified tissue and other material are broken down for removal from within a body using laser pulses that are delivered via an optical fiber and have a wavelength, intensity, energy per pulse and pulse duration selected to break down the object into smaller particles without delivering energy sufficient to cause damage to other tissue.
