Abstract:
:Carbon dioxide laser energy was used for the dissolution of atheromatous plaques. Flexible, nontoxic infrared optical fibers were used for the transmission of the carbon dioxide laser beam intraarterially. Dissolution of plaques and recanalization of obstructed arteries were achieved both in vitro and in vivo with controllable damage to the vessel walls.
