Project Description

The purpose of this image is to accurately depict the action of the Sapphire, a laser used in the ablation of urinary stones. The laser generator is the capital equipment and the laser fiber is the flexible device that connects to the generator and is inserted through a scope into the patient’s kidney to ablate the stone using the (green) laser beam. The urologist will either use the laser to fragment the stone into large pieces and then retrieve the pieces with a basket, or dust the stone into fine particles (this depiction) which the patient later passes naturally. The Sapphire features a special mode for reduced retropulsion during dusting. This mode produces a modulated pulse which first creates a bridge of vapor (in the form of connected air bubbles) between the fiber tip and stone, and then uses the laser beam to dust the stone through the vapor. This effect reduces the chance that the stone will move away from the fiber (‘retropulsion’).
